RMAG SEPT. 2021 BOARD OF DIRECTORS MEETING

By Jessica Davey, Secretary jessica@desertmountainenergy.com

Membership Committee is getting ready to judge all of the Geohike Challenge entries! Also, keep an eye out for the Mentorship Program applications, which should open n October for the 2022 program. The Publications Committee is recruiting articles for the Outcrop and is also still working away at the 100-year anniversary specials for the Outcrop and Mountain Geologist. The On the Rocks Committee has started pulling together an incredible list of field trips for 2022 – I’m looking forward to seeing what’s in store! The Educational Outreach Committee has been very busy working on establishing relationships and may even host a gold panning event for some very lucky fifth and sixth graders. The Ad Hoc Committee on Diversity and Inclusion has been compiling framework on how the committee will work going forward and work to better RMAG as an organization, creating more awareness of diversity in geological sciences.

Iceland has been on my bucket list for quite a while and has moved up several positions since the Fagradalsfjall volcano has been erupting. I wrote a few months ago about the livestream video of the volcano, which is still available to view. Even more breathtaking are the nighttime aerial photos that have been posted on social media lately. There is a stunning drone video on YouTube. Makes me want to visit very soon!

It’s feeling like fall – finally! Do you have any plans to get outside before snow starts falling and covering up the outcrops?

The 2021 RMAG Board of Directors once again met virtually at 4 pm on Wednesday, September 15.

Everyone was present for the meeting except for Jeff May. Treasurer Rebecca Johnson Scrable reported that the RMAG financials continue to look good for 2021 despite the continued lack of events; the investment account has continued to perform well over the past few months. Kathy has continued to manage the RMAG operations remotely from her home, and RMAG is getting closer to hiring an Executive Director.

The Continuing Education has postponed in-person luncheons due to recent up-tick in COVID-19 cases; luncheons will remain virtual for the time being. The Committee has also started planning for the 2022 Fall Symposium, stay tuned for details. The

RMAG Field Trip/Short Course

Sediment-Hosted Vanadium and Uranium of the Colorado Plateau Led by Dr. Ali Jaffri

Moab, Utah

Oct. 28-29, 2021 The Colorado Plateau is one the most prolific Vanadium-Uranium producing areas in the world. Many of the mining industry’s models of sediment-hosted metal occurrence are based on field observations from famous the Slickrock and Henry Mountains Mining District.

$700/members $750/nonmembers Student discount available See website for full details

On this field trip you will tour mines that have historically produced from fluvial sandstones that are close to environmentally sensitive locations such as rivers and campgrounds.

These locations have been selected out of 500+ mines in the area based on safety, logistics (less hiking more looking at rocks), and where mineralization can still be seen in the host rock.

This course is designed for geoscientists, engineers and environmental scientists working on metal exploration or mine remediation.

PRESIDENT’S LETTER

By Cat Campbell

It’s not what you are that holds you back, it’s what you think you are not.

—DENIS WAITLEY

I sat down with a sigh of relief. Done. My first formal presentation as a working geologist. Finally, I’d made it. Years of study and hard work culminated in this one experience: presenting a concept of water chemistry for field delineation.

Walking out of the conference room, another new grad stopped me. “You are either a genius or you have no idea what you are doing.”

I instantly felt the energy and exhilaration I’d experienced moments before evaporate. What was I doing here? What made me think I was good enough to succeed in this industry of innovation when I am clearly incompetent? I slowly made my way back to my office, defeated and questioning the future I had envisioned for myself as a geologist.

Why wasn’t my reaction that day the opposite?

Why didn’t I respond with a “thank you, I would be happy to explain the concept in further detail to you”?

Imposter Syndrome. Rearing its ugly head and destroying the fragile thread of confidence that seemed to be holding me together.

external factors such as luck or good timing rather than inherent ability and effort (Bravata et al, 2019).

This constant striving for perfection, questioning oneself, and comparing oneself to others can lead to burnout and cause poor job performance.

Ironically one of the triggers of imposter syndrome is acknowledging someone’s success. Pointing out a job well done, giving someone an award, or congratulating a promotion can cause someone to question his or her ability and wonder if the acknowledgement is deserved.

I still believe that at any point the notalent police will come and arrest me.

—MIKE MYERS

Psychology Today describes people who experience imposter syndrome to “believe that they are undeserving of their achievements and the high esteem in which they are, in fact, generally held. They feel they aren’t as competent or intelligent as others might think- and that soon enough, people will discover the truth about them.” (Imposter Syndrome | Psychology Today) Imposter Syndrome is typically classified into five types: Perfectionist, Superperson, Natural Genius, Soloist, and Expert (Figure 1). Each type has unique characteristics, but they all share the common approach of attributing their successes to OUTCROP | October 2021

I still have a little imposter syndrome… It doesn’t go away, that feeling that you shouldn’t take me that seriously. What do I know? I share that with you because we all have doubts in our abilities, about our power and what that power is.

—MICHELLE OBAMA

How do you combat imposter syndrome? One key is realizing that this is a very common phenomenon, and that it is something that is okay to talk about.

RMAG SHORT COURSE

Kinematics and Structural Styles of Extension, Contraction, Strike-Slip, and Inversion with Dr. Molly Turko

11 / 10 & 11 / 2021

Online

This 2-module structural geology course will give participants the opportunity to understand the relationship between the kinematics of various folding and faulting styles related to stress and mechanical stratigraphy from the regional basin scale down to the outcrop. We will cover structural styles of extension, contraction, strike-slip, and inversion. Styles of contraction will include both thick-skin (basement involved deformation, i.e. Laramide Orogeny) and thin-skin (no basement involved, i.e. Sevier Orogeny).

Concepts of transpression and transtension will be included in our discussions on strike-slip faulting, as well as how they can develop during structural inversion and/ or reactivation of pre-existing structures.

PRESIDENT’S LETTER

» CONTINUED FROM PAGE 8

More than a decade after that first talk, I found myself sitting at a table at Colorado School of Mines leading a discussion on imposter syndrome.

I told the story about my first talk and my mentor Terri Olson looked at me and asked why I didn’t just come talk to her about it. She was present at that meeting when I presented my work and was pleased with my conclusions. She was shocked to learn that I felt inadequate and reminded me that this is precisely what mentors are for. From time to time I’ll get an inkling that I am in over my head or will not be good enough at something, but I took Terri’s advice and reach out friends, mentors and peers and talk about my concerns. I need to remind myself that we never stop learning and no one is perfect at everything they do.

You don’t have to be an expert.

No one is expecting you to be an expert. All you need to do is how up and be you.

was started in the summer of 2020 as an effort to bring a separated and quarantined membership together for a shared, yet physically distant event where we could connect through pictures and stories posted in a social media platform. We brought this idea back in 2021 and tried to make the scavenger hunt items more diverse so people could participate from anywhere. Sure enough, the loosening of travel restrictions brought submissions from coast to coast in the US, and all over the world! See the fantastic photos from Megan Cornelissen, Brenda Wiard, Ron Parker, Katie Joe McDonough, and more in this issue.

The geological scavenger hunt list was expanded from last year, and Katie Joe was the fastest at finding items and posting them. The Ansel Adams award is for the most artistic and stunning photos of scavenger hunt items. The close competition between Ron and Brenda benefits us all.

Enjoy seeing geology through their eyes and cameras.

The photo contest winners are also featured below. From goofy categories like Most Outrageous Apparel (thank you, Cat, you always make us laugh) to Cutest Furry Family Members, we enjoyed time outdoors and also took a minute to note the geology under our feet and surrounding us. This sometimes resulted in our hiking companions getting an unintended earth science lesson, but that has got to be a good thing, right?

WHY DO YOU WANT TO BE PART OF THE RMAG BOARD?

PROFESIONAL EXPERIENCE

10 years bp/bpx, focusing on rocks as much as possible. I started with bp in the subsurface technology team supporting a rebuild of the stratigraphic framework of Thunder Horse Field. Then I gained ops experience drilling and coring Utica and Woodford wells. I then joined the Wamsutter development team and worked stratigraphy of the Almond, Lewis, and Fox Hills systems, as well as led two field trips to the outcrops of the same units.

My first role in bpx, after we were separated from bp, was in the exploration team, providing sed/strat support to the Wamsutter business as well as evaluating acquisitions. Since moving to the bpx headquarters in Denver 3.5 years ago, I have been on the San Juan and Permian Development teams prospecting, planning and geosteering wells.

I am now over one year into my subsurface technology team role, largely providing sed/strat technical work for Permian business and shepherding geologic data management for bpx.

INVOLVEMENT WITHIN RMAG AND OTHER PROFESSIONAL ORGANIZATIONS

I believe in professional societies; they foster knowledge sharing and camaraderie that facilitates collaboration across companies. I’d like to offer my energy and leadership skills to the hierarchical organization of RMAG, helping guide committees as well as reporting to and from the Board. Being one of the Outcrop coeditors showed me how much work that role can be, but also allowed me to find new ways to solicit articles.

Publishing peer reviewed papers and newsletters is a big, mostly extracurricular aspect of a professional geoscientist and I believe I can help facilitate these efforts, as well as provide input to the direction of RMAG.

WHY DO YOU WANT TO BE PART OF THE RMAG BOARD? In short, to let geologists spend more time interpreting geology. I believe applied data science education will make us better geoscientists and free us from many repetitive workflows.

I’ve been contributing to several projects that lower the barrier for entry of other geoscientists to learn the transferable skill of python programming. These programs improve continuing education opportunities for working geologists and employment prospects for the next generation. Serving as Second Vice President with the Continuing Education Committee aligns with my personal goals and would allow me to widen the scope of people that I assist in picking up new tools for their toolbelt.

Coincidence or Consequence The timing of late Devonian active margin tectonism and sedimentation in the intracratonic Williston Basin

By Michael Hofmann environmental controls of these black shales, as oceanic anoxic events, glaciations, and major tectonism were contemporaneously at play during this time. Along the western margin of the North American continent, the latter resulted in orogenic loading during the Antler orogeny (370– 340 Ma).

The Williston Basin is located atop the structurally complex suture zone between the Archean Superior province to the east and the Archean basement of the Wyoming structural provinces to

The Late Devonian (~360 million years ago) was an interval characterized by globally widespread deposition of fine-grained, organic-rich sediments. Many of these ‘black shale’ deposits contain >10 wt% total organic carbon, and are associated with economically important hydrocarbon targets. In the northern Rocky Mountains the best known member of these Late Devonian (and earliest Carboniferous) black shales is the Bakken Formation in the Williston Basin, located in northern USA and southern Canada.

Key questions are about the synchroneity and

» CONTINUED ON PAGE 50

MICHAEL HOFMANN: In the most general terms, I am a geologist who seeks to understand the processes responsible for transportation, deposition, and preservation of sediments, at a variety of scales from pore scale to basin scale. As such, it is critical to me to look at processes that shape our world holistically, and to consider their dependencies when studying the rock record. Rocks exposed in outcrops or cores are the best archive of these inter-dependencies and are at the heart of my work, although my research is supplemented by a multitude of other methods and data, including remote sensing, geophysical, geochemical, paleontologic, geomorphic, and numerical modeling.

After receiving my Dipl.-Geol.-Univ. (M.S. equivalent) degree from the University of Erlangen-Nuremberg, Germany, I made my way to Montana and received a Ph.D. in Geology from the University of Montana. Following my academic training, I worked as a senior geologist for ConocoPhillips’ Subsurface Technology, Sedimentary Systems, and Shale Stratigraphy groups in Houston, TX, where I worked in sedimentary basins and on projects from around the globe. Despite being a very rewarding and exciting opportunity, I could not resist the call of the Rockies, and was fortunate enough to be able to come back to Montana.

Here I continue working on rocks from around the globe, across North America, and right here in the Rocky Mountains as an Associate Research Professor at the University of Montana, as well as the co-founder of AIM GeoAnalytics (a Montana based rock analytical lab), and co-founder of Cartalytics (a spatial data analytical platform).

It is my goal and passion to share with students, colleagues, and the public the awe and excitement that I find when looking at rocks and thinking about the controlling processes, and I look forward to discussing my ideas about the Bakken Formation with the distinguished group of RMAG members.

HYBRID LUNCH TALK the Lower Bakken Shale and the Pronghorn Member, reveal a more complex basin geometry.

This talk provides a detailed picture of facies changes observed in the lower Bakken Formation. It takes a closer look at latest Devonian global and local environmental factors that could have controlled the observed lower Bakken facies distribution in the Williston Basin. In particular it provides food for thought how continental margin tectonism during the latest Devonian might have influenced deposition in an intracratonic basin located hundreds of miles from an orogenic front.

the west. This intracratonic basin in general has a very homogeneous subsidence history throughout most of the Paleozoic, that can be largely explained by simple thermal subsidence. This simple subsidence model is expected to result in a very predictive facies distribution with more proximal facies near the basin margin and the more distal deposition near the basin center. Although this type of facies distribution is observed for most of the Devonian strata in the Williston Basin, detailed facies and geochemical analysis of the lower Bakken Formation members, namely

Combined field mapping, measured stratigraphic sections, and balanced cross-sections of the Pennsylvanian-aged Eagle Valley Evaporite and overlying Late Pennsylvanian to Jurassic-aged strata indicate a long-lived phase of salt tectonics in the Eagle Basin, central Colorado. Diapiric salt structures exposed at the surface represent a series of formerly connected, polygonal salt walls flanked by deep, elongate minibasins in the

area interpreted these structures to be the result

of the Laramide Orogeny and younger tectonism; however, the proposed phase of salt-influenced

deformation in the Eagle Basin has a similar history to the Paradox Basin to the southwest and suggests a new paradigm for the tectonic and stratigraphic evolution of this region.

Bruce Trudgill is a structural geologist in the Department of Geology and GE at the Colorado School of Mines, where he has taught undergraduate and graduate course for over 18 years. His research interests are focused on structural controls on depositional systems and he has been working on the salt structures in the Paradox Basin for over 20 years. More recently, fieldwork with graduate students and colleagues has led him to the mountain ranges of Central Colorado, mapping pre-Laramide salt structures across the region. In his spare time Bruce spends as many days as possible hiking in his local mountain ranges: the Indian Peaks and James Peaks Wilderness areas.

RMAG ON THE ROCKS

Detroit City Portal/ Rhodochrosite Mine Trip August 20, 2021

By David Schoderbek

On Friday, 20 August, six lucky RMAG members accompanied Dean Misantoni, Colorado Calumet geologist and local mining history treasure-trove, into the Detroit City Portal, an upper-level extension of the Sweet Home Mine.

Silver/lead/zinc/copper ores from the Sweet Home Mine, located approximately four miles west of Alma, Colorado, were produced intermittently from 1875 until 1967. Even from its earliest days, though, the Sweet Home workings were known for occasional discovery of cherry-red rhodochrosite mineral specimens. The Sweet Home Mine was exploited and expanded for mineral specimens by a variety of operators Map of the Sweet Home Mine from Misantoni, in Bartos, et al, 2007 from 1967 through 1985, when efforts ceased.

Collector’s Edge and its affiliates, under the leadership of Bryan Lees, leased the Sweet Home and has been associated with mining and exploration Mine in 1991, purchased it and surrounding claims in core-drilling all of that time, including long tenures at 1998, and expanded the underground workings for the prolific nearby London Mine and the Sweet Home rhodochrosite specimens until 2004.

Once we were suited-up with personal protective gear (hardhats, steeltoed boots, safety glasses, gloves, & coats), we headed into the slightly inclined Detroit City Portal. The portal was driven into Mount Bross to intersect the main (“Tetrahedrite”) rhodochrosite-mineralized vein, with raises developed upward along the vein, followed by opening of drifts and stopes along the mineralization. Drifts, raises, and stope have been developed along other productive associated veins.

In addition to Mine (SHM), after Lüders, et al, 2008 jackleg drills, fiber-optic “drillhole cameras,” diamond saws, and gentle hydraulic “feather and wedge” splitters are employed to carefully open mineralized pockets. Mineral specimens are not recovered by miners; instead, they are collected by white-gloved specialists once a mineralized pocket has been carefully exposed. While our tour did not see any of the rare, large, cherry-red, euhedral “rhodos” for which the Sweet Home Mine is famous, we did see bright red “smashed rhodos” tightly embedded in quartz matrix, and were able to peer into barren vugs containing euhedral fluorite and pyrite crystals.

Our tour included virtually all of the safely accessible mine workings, and we had the opportunity to scramble up into a raise that was being driven vertically along the Tetrahedrite Vein – fascinatmine, Alma District, Central Colorado: The porphying!

The Wave

Letter to the Editor

Alone

Editor’s Note: Robbie Gries reached out in response to our recent article on Colorado’s state rock, the Yule Marble, to share this story about Anny Bustab Coury.

Our retired member, Anny Bustab Coury, age 92, started sculpting when working as an exploration geologist working for Union Texas in Houston, Texas in the late 1950s, early 1960s. (Her boss was Frank Sonnenberg, father of none other!) She was in exploration for 19 years and finished her career with the Oil and Gas Branch of the USGS. Upon retirement, she poured herself into her former hobby, sculpting. Her Yule Marble pieces include those picutured here.

Anny escaped the Nazis with her parents as a child in France during WWII, entered the University of Texas at age 15, taking her geology degree in 1949 at age 19 and beat the streets of Houston for a job when she had to compete with returning GI’s and strong aversions to hiring women. She was undaunted. And still is! Her website is annyrocks.com.

She is one of my heroes!
