Stratigraphy and copper deposits of the Abo Formation, Abo Canyon area, central New Mexico
William O. Hatchell, John W. Blagbrough, and James M. Hill
The purpose of this report is to describe the stratigraphy of the Abo Formation of Permian age within and adjacent to the type section, as well as to redefine the type section established by Needham and Bates (1943). Lithofacies are identified; supplementary measured sections, sedimentary structures, and fossils are described; and depositional environments are inferred. In addition, the copper deposits and uranium occurrences of the Sholle district, their relationship to Abo stratigraphy, and the history of discovery and copper production are discussed.
The late C. B. Read of the U.S. Geological Survey originally suggested and guided the stratigraphic work needed to redefine the type section, and contributed his knowledge of Permian flora by identifying the fossil plant collection. W. 0. Hatchell measured the stratigraphic sections and described the Abo and its depositional environment. J. W. Blagbrough investigated the copper and uranium occurrences and described the geology of the deposits. The history of mining and the production statistics were compiled by J. M. Hill.
