The northern Walker Lane in from a convergent to a transform margin in northwest Nevada and northeast California occupies the northern terminus of this system. the past 30 m.y., the northern Walker Lane has This young evolving part of the plate boundary offers insight into how strike-slip fault undergone widespread volcanism and tecto- systems develop and may re¯ect the birth of a transform fault. A belt of overlapping, left- nism. Tertiary volcanic strata include 31±23 stepping dextral faults dominates the northern Walker Lane.

WASHOE COLINTYNEVADA I I I I I I I I I I I I I Michael C.Widmer t Washoe County Department of Water Resources t Reno- Nevada October 2001 T I I I LINEAMENT ANALYSIS OF' AN AEROMAGNETIC SURVEY, WARM SPRINGS VALLEY, WASHOE COUNTY, NEVADA I Introduction This report discusses a lineament analysis of aeromagnetic data for Warm Springs Valley. The results can be used to further the understanding of geologic structure, particularly fault structure. I The analysis combines recent work with a previous report by Paul Hartley (1995), under contract with the Washoe County Department of Water Resources. His analysis was to determine the I depth of bedrock and the delineation of sediments within a portion of Warm Springs Valley. Airborne Geophysical Data Dighem, Inc. was contracted by Washoe County to conduct an airborne geophysical survey I (Dighem, 1994). Magnetic and electromagnetic instrumentation was installed in a Lama turbine helicopter (Geoseis Helicopters, Inc.) which flew at an average airspeed of 100 kph (62 mph) I with a magnetometer bird height of 30 meters (98 feet) above ground level. The survey consisted of 414 kilometers of traverse line (257 miles) oriented at 50'1230'to geographic north with 667 meters (2000 feet) line spacing. Two tie lines were oriented at 140'1320o to geographic ! north. The magnetic data was collected with a Picodas 3340 optically pumped cesium vapor magnetometer. The sampling rate was l0 per second with a sensitivity of 0.01nT. Navigation and positioning consisting of a Sercel NR 106 real-time differential global positioning system I with <5 meter accuracy.
