Report: Stratigraphy, Structure, Hydrothermal Alteration and Ore Mineralization Encountered in CSDP (Continental Scientific Drilling Program) Corehole VC-2A, Sulphur Springs Area, Valles Caldera, New Mexico- a Detailed Overview

Abstract
The pyroclastic and volcaniclastic rocks penetrated by the corehole are readily recognizable from previous studies of the Valles calderas surface and subsurface, and include most major members of the 3.6-<1.12 Ma intracaldera volcanic sequence. Continuous core from VC-2A, however, has revealed critical textural and structural features of these rocks not apparent from earlier investigations based on small-diameter drill cuttings; paragenetic relationships among hydrothermal phases have been similarly clarified. Our work to date on the VC-2A core has led to the major preliminary conclusions. 35 refs., 3 figs.
