Abstract: Laboratory tests were conducted on rock core samples received from ten core holes drilled in the Laramie range, Wyoming, to determine the integrity and mechanical behavior of the materials. The results were to be used to determine the usefulness of the Warren Sitting Area for potential missile sites. Series I tests (relative hardness specific gravity, compressive strength, sonic velocity, etc.) indicated the materials to be relatively uniform, competent granite, diorite, and gneiss rock, Series II tests (triaxial, hydrostatic, and confined compression) indicated the rock to be rather incompressible and brittle up to 36,000-psi triaxial stress. Series III tests indicated that the granite and diorite had Hugoniot elastic limits of 50 kilobars or more and the gneiss approximately 20 kilobars. In order to better define the physical and mechanical behavior of the rock, triaxial tests to approximately 150,000 psi on intact and jointed specimens and e~uation of state tests at pressures to approximately 600 kilobars should be conducted.
