12. Igenous: granite and basalt, Sedimentary: sandstone, limestone Metamorphic: marble, slate For sculpture: marble and sandstone
13. Quicklime is CaO. Slaked lime is Ca(OH)2. Slaked lime is formed when quicklime reacts with water.

14. Sinkholes are formed in karst terrains consisting of limestones. When the limestones beneath the ground get dissolved by the rain water, cavities are formed. When they collapse the ground above subsides, forming these cavities.
15. Faults, joints, bedding planes, schistosityand cleavages are different types of discontinuities. Surf the web.

For granite, from Table 4.3, = 0.2
From Table 4.7, c = 200 MPa
From Table 4.4, E/c = 450
Therefore E can be taken as 450200 MPa = 90 GPa
Noting that we are dealing with principal stresses and strains here,

18. Rock mass gives the big picture. It contains intact rock as well as the many different discontinuities (e g., fissures, joints, bedding planes). Intact rock is simply a small specimen taken from the rock which is often free of any discontinuities.

SASW = Spectral Analysis of Surface Waves
