SACHSE MONUMENT PENDANT, CENTRAL SIERRA-NEVADA, CALIFORNIA - EUGEOCLINAL METASEDIMENTARY ROCKS NEAR THE AXIS OF THE SIERRA-NEVADA BATHOLITH

Sachse Monument pendant, located near the axis of the Sierra Nevada ba tholith in the central Sierra Nevada, exposes an assemblage of eugeocl inal metasedimentary rocks that consists of tightly to isoclinally fol ded siltstone, sandstone, argillite, chert, limestone, limestone-clast conglomerate, and quartzite. The eugeoclinal rocks lie structurally a bove the miogeoclinal rocks of Snow Lake pendant along a structural br eak which is intruded by a 148 Ma igneous complex. Structural and stra tigraphic studies at Sachse Monument pendant provide new supporting ev idence for large displacement on the Mojave-Snow Lake fault, a propose d intraarc, right-lateral strike-slip fault that may have displaced mi ogeoclinal rocks in the central part of the Sierra Nevada from an orig inal position in the Mojave Desert. Geologic features of Sachse Monume nt pendant, including eugeoclinal rocks that rest structurally upon mi ogeoclinal rocks, and a 148 Ma igneous complex, together with other fe atures, are characteristic of the western Mojave Desert region.
