Abstract
In this central chapter Coulomb-Mohr’s theory of faulting is applied to:
-
1)
normal and thrust faulting in rocks composed of layers differing in strength, rheology and pore pressure;
-
2)
the mechanical causes of listric faulting in various geological settings (sediment slopes, ice loads, substratal flow, thrusting and rifting, subsiding basement blocks, compaction, etc.);
-
3)
the role of antithetic faults and continuous ‘double-shearing’ in adjusting sliding rock masses to changes in shape or position of the sliding path;
-
4)
the ‘bookshelf’ operation of parallel antithetic faults in accommodating tectonic (quasi-) simple shearing;
-
5)
providing a mechanical explanation of the paradoxical stress orientation along the San Andreas fault, California.
