Principles of cementation, environmental framework and diagenesis of the Grayburg and Queen formations, New Mexico and Texas

by Karl Wendel Williams

This investigation consists of a detailed diagcnetic study of the Grayburg and Queen Formations conducted within the context of the depositional and post-depositional environmental fraraework. Paleogeography, paleoclimatology, and depositional dynamics of these formations are described, and analogous recent sedimentological and diagenetic models proposed. Data utilized in environmental reconstructions were collected from Grayburg and Queen outcrops as well as from subsurface core and core chip samples from 43 oil V7ells located throughout the Northwest Shelf and Central Basin Platform (Figure 3 and Plate 1). Types of evidence evaluated include stratigraphic relationships, primary sedimentary structures, genetic sequences, directional data, paleontologic, textural, mineralogical data, and core test data.
