Exploration Basis
Analyze fault block kinematics at a releasing stepover of the Eastern California shear zone to determine the partitioning of rotation style
Rotations paleomagnetically relative to two different reference frames were measured. At two localities, the secular variation were averaged through sedimentary sections to reveal rotation or its absence relative to paleogeographic north. Where sediments are lacking, a really-extensive lava flows from individual cooling units or short eruptive episodes were used to measure the relative rotation of localities by comparing their paleomagnetic remanence directions to one another.
