KINEMATICS OF THE EASTERN CALIFORNIA SHEAR ZONE - EVIDENCE FOR SLIP TRANSFER FROM OWENS AND SALINE-VALLEY FAULT ZONES TO FISH-LAKE VALLEY FAULT ZONE

Late Quaternary slip rates and satellite-based geodetic data for the w estern Great Basin constrain regional fault-slip distribution and evol ution. The geologic slip rate on the Fish Lake Valley fault zone (the northwest extension of the Furnace Creek fault zone) increases northwa rd from about 3 to 5 mm/yr, in agreement with modeled geodetic data. T he increase coincides with the intersections of the Deep Springs fault , connected to the Owens Valley fault zone, and of other faults connec ted to the Saline Valley fault, The combined geologic and geodetic dat a suggest that (1) the northwest-striking faults of the Eastern Califo rnia shear zone north of the Garlock fault are connected by north- to northeast-striking normal faults that transfer slip in a series of rig ht steps, and (2) the amount and distribution of slip among the many f aults of this broad, complex plate boundary have changed through time.
