Purpose
|
Study deep seismic structure of Transverse Ranges, Los Angeles Basin,
and Inner Continental Borderland
|
|
|
Information to be Derived
|
Multi-channel images of southwest edge of Los Angeles Basin
show basin sediments truncated at large northeast dipping system of
structures that separate them from Catalina Schist basement to the
southwest. Moho beneath the Inner Continental Borderland is flat at
about 14 km depth and it dips northeast to 20 km beneath Los Angeles
Basin.

Summary
|
Data were gathered along three long profiles, all of which extended
both onshore and offshore. One extended from the Mojave Desert to San Clemente
Island, a second from Soledad region to the region west of San Clemente Isand,
and a third from Orange County to the area offshore south of the northern
Channel Islands.
