...STEPHEN J. MARTEL; DAVID D. POLLARD; PAUL SEGALL Abstract Simple strike-slip fault zones mark the third stage of faulting in granitic plutons in the Mount Abbot quadrangle of the Sierra Nevada of California. Deformation began with the opening of nearly vertical subparallel joints. These joints were...

... in the Mount Abbot quadrangle of the central Sierra Nevada, the host granodiorite is hydrothermally altered to a lower greenschist assemblage that contains muscovite. The muscovite yields a mean K-Ar and 40 Ar/ 39 Ar age of 79 Ma, which provides a minimum age for the faulting. Field relations show...

In addition to these brittle structures, Tikoff (1994) and Tikoff and de Saint Blanquat (1997) examined zones of steeply dipping, north-northwest–trending foliation mapped by Lockwood and Lyndon...
