INTRODUCTION

During 1980 and 1981, the U.S. Geological Survey collected seismic refraction data in

the western Mojave Desert (fig. 1). The seismic refraction data extends from north of the

Garlock Fault, south through the Mojave Desert, and across the San Andreas Fault into the

San Gabriel Mountains. This report describes and documents the recorded data, which was

collected over three field sessions. In total thirteen shots were fired at 11 different shotpoints

(Table 1). The experiment consisted of five deployments of a set of 100 portable seismic

recorders, during which seismic energy from one or more shots was recorded. The data set

was acquired with five deployments of a set of 100 portable seismic recorders.

The first phase (deployments 1-3; figs. 2 - 4), in June 1980, was designed to investigate

P-wave anisotropic-velocity using a south trending profile with two cross-arrays. Station

spacing for these deployments was about 0.5 km. The U.S. Geological Survey loaded and

detonated all shots in the first phase.

The second phase of the experiment (deployments 4 and 5; figs. 5 and 6), in April and

November 1981, recorded two quarry blasts (shots 10 and 11) and a missile detonation (shot

12) so that the profile from phase one could be extened to the north and south. Station

spacing for these deployments was about 1.5 km. During this phase of the experiment some

of the original recording sites were reoccuppied. Given and Koesterer (1983) describe shot

number 13, which was detonated on Santa Catalina island.

Shot times and shotpoiiit locations are presented in table 1. Geographic locations for

each recording site are in table 2. The location of each recording site relative to the shot

point and information about each data recording for that site is provided in table 3. Seismic

record sections are plotted in figures 7 - 38. The data is stored on magnetic tape in SEGY

format, described by Barry and others (1975), and may be obtained by writing the National

Geophysical Data Center, National Oceanic and Atmospheric Administration, 325 Broadway,

Boulder CO, 80303.

On the basis of this data and in-situ stress measurements Kohler and Healy (1981)

suggest that P-wave anisotropic velocity arises from the action of tectonic stress on high-

angle macro-factures. Fuis and others (1986) modeled the crust along the north - south profile

between shotpoint 12 and the San Gabriel Mountains. Other work in the area includes

six deep seismic reflection profiles collected by the Consortium for Continental Reflection

Profiling in 1982 (Cheadle and others, 1986).

INSTRUMENTATION

Each seismic refraction recorder consists of a 2-Hz vertical component seismometer cou

pled to an analog tape cassette recording system (Healy and others, 1982) The electronics,

including signal response, calibration and diagnostic tests is described by Murphy (1988).

DATA PROCESSING AND EDITING

For each shot, 20 seconds of seismic signal from playback of cassette data tapes were

digitized at 200 samples/sec. The digitizing start time (T) is calculated from:

T = S- 2sec + XIR + C

where

S = shot time (Table 1),

X = shot to recorder distance in km (Table 2),

R = reduction velocity in km/sec,

C = recorder clock drift in seconds.

Recorder and shotpoint locations were determined from USGS 7.5' and 15' topographic maps

and are estimated to be accurate to 10 meters. Shotpoint to recorder distances are calculated

2

with the algorithm of Sodano and Robinson (1963). The reduction velocity for all shots

except shotpoint 13 is 6.0 km/sec; a reduction velocity of 8.0 km/sec was used for shotpoint

13. The clock drift of each recorder was checked before and after each deployment and was

assumed to be linear. Estimated drifts at shot time were usually less than 50 milliseconds.

Record sections, shown in figures 7-38, are plotted with the maximum amplitude for

each trace normalized to a common value. Distances are relative to the shotpoint, except as

noted, and distances to the west and north of the shotpoint are given negative values.
