The Mississippian System of southwestern New Mexico and southeastern Arizona
Augustus K. Armstrong and B. L. Mamet
This report focuses on the Mississippian rocks of southwestern New Mexico and southeastern Arizona and, in particular, the Pedregosa basin. Greenwood and others (1977) give the geologic history of this basin and summarize its petroleum potential and stratigraphy. The data for northern and central Arizona are taken from McKee and Gutschick (1969) and McKee and Crosby (1975). A detailed description of the Mississippian rocks of north and north-central New Mexico is given by Armstrong and Mamet (1974, 1976, 1977a). This report is preliminary, and detailed analysis of the microfacies, microfossils and diagenesis of the carbonate rocks is in prep-aration. Mamet's microfossil zonations, as defined in Sando and others (1969), Mamet (1976), and Mamet (in Armstrong and Mamet, 1977b), are used in this report. The carbonate rock classification used is Dunham's (1962).
