Subsurface stratigraphy of the Morrison Formation in the Mount Taylor area and its relation to uranium ore genesis

This article is an outgrowth of a subsurface stratigraphic study of the Morrison Formation present near San Mateo, New Mexico, on properties being explored and developed by Gulf Mineral Resources Company (fig. 1). This project was under taken as part of a M.S. thesis project for the University of New Mexico. The principal aim of this study has been to carry out detailed stratigraphic correlation through the use of electric logs, core analysis and thin section analysis in order to define the paleoenvironments of the Jurassic Morrison Formation in the Ambrosia Lake and Mount Taylor areas and to determine what roles these environments have played in uranium ore genesis.
