Preshot Geophysical Properties of Palanquin Crater Site
Abstract
The Palanquin nuclear cratering experiment was conducted on April 14, 1965 at the Nevada Test Site of the U. S. Atomic Energy Commission. Eight preshot holes were drilled which consisted of the emplacement hole, two instrument holes, and five exploratory holes. The maximum depth reached was 187 m. The rocks at the Palanquin site are of volcanic origin, and consist predominantly of trachyte porphyry of the Ribbon Cliff formation of Pliocene age. Pyroclastic volcanic tuff underlies the trachyte porphyry at a depth of 175 m and caps low hills adjacent to the site. The volcanic units have a general horizontal attitude, although flow structures show gentle-to-steep dips. No ground water was encountered.
