Sierra Nevada-Basin and Range Transition Near Reno, Nevada: Two-Stage Development at 12 and 3 Ma
Dataset Identification:
Resource Abstract:
ABSTRACT - Relative and absolute elevations of the Sierra Nevada and adjacent Basin and Range province, timing of their differentiation,
and location, amount, and timing of strike-slip movement between them are controversial. The provincial boundary near Reno
developed in two stages. (1) At ca. 12 Ma, the (greater than or equal to) 700 km2 Verdi-Boca sedimentary basin formed across
what was to become the boundary, probably as a result of a small-magnitude but regional extensional episode that affected
much of the western Basin and Range. (2) At 3 Ma, the basin was complexly faulted and folded during a larger magnitude extensional
episode that established the modern Sierran structural and topographic boundary in this area. The boundary is really a transition
zone with a western edge along the Donner Pass, California, fault zone, which is farther west than previously placed. Both
episodes appear to have resulted from east-west extension only, which suggests that northwest motion of the Sierra Nevada
relative to the Basin and Range shown by geodetic data began after 3 Ma or was taken up farther east.
