Geologists have long grappled with understanding the mechanical origins of rock deformation. Stress regimes control the nucleation, growth and reactivation of faults and fractures; induce seismic activity; affect the transport of magma; and modulate structural permeability, thereby influencing the redistribution of hydrothermal and hydrocarbon fluids. Experimentalists endeavour to recreate deformation structures observed in nature under controlled stress conditions. Earth scientists studying earthquakes will attempt to monitor or deduce stress changes in the Earth as it actively deforms. All are building upon the pioneering research and concepts of Ernest Masson Anderson, dating back to the start of the twentieth century. This volume celebrates Anderson's legacy, with 14 original research papers that examine faulting and seismic hazard; structural inheritance; the role of local and regional stress fields; low angle faults and the role of pore fluids; supplemented by reviews of Andersonian approaches and a reprint of his classic paper of 1905--

The Oquirrh Fault Zone, Tooele County, Utah: Surficial Geology and Paleoseismicity
This thesis addresses long-standing controversies surrounding normal faults that initiate and slip at low-angles (30°) and are responsible for extreme crustal extension (100%).
Trench 3 contains three zones of concentrated deformation. Fault zone 1 (FZ1 on figure 28) consists of two normal faults that underlie 8-meter-high Scarp G at the east end of the trench. The eastern fault has 3 meters of throw on unit ...
