PRESHOT GEOPHYSICAL STUDIES OF CABRIOLET NUCLEAR CRATER SITE

摘要

The Cabriolet Event was a Plowshare Program nuclear cratering experiment to obtain basic data on cratering phenome¬nology and distribution of radioactivity. The 2.5-kt device was buried 52 m deep in hard, dry Ribbon Cliff trachyte.nCabriolet ground zero is located at Nevada State coordinates N 921,250 and E 544,286 in the northwest corner of Area 20, Nevada Test Site. The surface elevation is 1895 m. Density logs were run in five of the seven holes drilled at the site, caliper logs in six, uphole seismic surveys in three, and three-dimensional velocity logs in two.
