Comment on "The Butte Valley and Layton Well thrusts of eastern California: distribution and regional significance" by Chester T. Wrucke, Calvin H. Stevens, and Joseph L. Wooden
Article Abstract:
The interpretation of the Butte Valley fault as a thrust fault by Chester T. Wrucke, Calvin H. Stevens and Joseph L. Wooden fails to explain the absence of smaller faults and shear planes in areas of closest juxtaposition to the intruded fault. This sets the Butte Valley structure apart from other Middle to Late Jurassic thrust faults in nearby areas. Further, they do not report steep fault dips that are required near the plutonic sheet. The Butte Valley fault is better interpreted as a steep circular or semicircular fault formed during cauldron subsidence of strata during Jurassic pluton emplacement.

Article Abstract:
The interpretation of the Butte Valley fault as the margin of a collapse caldera by Gregory A. Davis and B.C. Burchfiel contains some basic problems. Much greater amount of collapse is expected than that common to calderas if their suggestion is to be accepted. There is also no evidence of expected intracaldera ashflow fill interleaved with collapse slide breccia. Further, no proof exists of the extensive silicic outflow whose eruption could have caused the collapse at that time. The original authors, however, welcome the collapse theory providing evidences supporting their thrust fault theory.

The Butte Valley and Layton Well Thrusts of eastern California: distribution and regional significance
Article Abstract:
The ages of the Butte Valley Thrust and the Layton Well Thrust, main structural features in the Death Valley region, eastern California, are about the same. They are formed in a narrow valley and belong to two adjacent mountain ranges, the Panamint Range and the Slate Range. The lower plates contain similar Paleozoic and mesozoic rocks. Upper plate rocks of the Layton Well Thrust are younger and different from the Butte Valley Thrust.
