Catalog of Principal Sedimentary Formation Names in Southern Arizona and Northern Sonora CATALOG OF PRINC IPAL SEDIMENTARY FORMAT ION NAMES IN SOUTHERN ARIZONA AND NORTHERN SONORA Willard D. Pye The following list of sedimentary formation names is restricted to those that are currently used in southeastern Arizona or have occurred frequently in geological lit­ erature. Some of this data is al so shown in the nomenclature cha rt, table 1. The te rms applied to stratig raphic units in Sonora are in flux, and ag e determi­ nations, boundaries, and correlations chang e rapidly as additional work is done. Names identical to tho se used in Arizona have been omitted. In some cases the orig­ inal references have not been available and information ha s been derived from other sources, particularly the 1937 issue of the U. S. Geolog ical Survey Lexicon of Geol­ ogic Names and its 1957 supplement. Special acknowledgment is due to Dr. Carl Fries, Jr., for hi s assistanc e with the Sonoran units both he re and in the nomencla­ ture chart. The presence of unnamed stratig raphic sequenc es of diffe rent ag es is indicated in the correlation chart. Some igneous rock names In current use ln southern Arizona are shown ln table 6 ( Titl ey, 12).

F.; Wilt, J.; Clemons, R. E.; James, H. L.; [eds.], New Mexico Geological Society 29th Annual Fall Field Conference Guidebook, 348 p. This is one of many related papers that were included in the 1978 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

Grace Wilmarth, published in 1938 and reprinted in 1951 and 1957, met a long standing need and continuing demand for a compilation of geologic names. Plans made for future compilations as new names and revisions appeared were interrupted during the years of World War II. In 1952 a sustained effort was begun toward review of geo­ logic publications necessary to furnish a background for preparation of a new edition. After the review was brought up to date in 1956, the present compilation was prepared in order to furnish to the geo­ logic profession, as quickly as possible, some of the essential data concerning the new names that have appeared since 1935.

    U. S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY GEOLOGIC MAP OF THE SILVER BELL AND WEST SILVER BELL MOUNTAINS, SOUTHERN ARIZONA By David A. Sawyer Denver, Colorado Open-File Report 96-006 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards (or with the North American Stratigraphic Code). Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. 1996 INTRODUCTION The Silver Bell Mountains, 50 km northwest of Tucson, Arizona, are a mountain range in the transition from the higher-relief mountains of southeastern Arizona to the low-relief ranges of the western Arizona deserts. The Silver Bell Mountains include the area of the Silver Bell mining district (Richard and Courtright, 1966) which has produced over 100 million pounds of copper (Graybeal, 1982) since mining began in the late 19th century. Most of the mountain range and adjoining flanks are composed of Upper Cretaceous volcanic and plutonic rocks which are interpreted as parts of a ash-flow caldera; the intrusions which formed the porphyry copper deposits of the Silver Bell mining district were emplaced into the caldera margin. The latest Cretaceous and early Tertiary period of formation of most of Arizona's many copper deposits during was also a period of widespread continental silicic caldera volcanism, later fragmented into alternating mountain range exposures and buried beneath alluvial basins by late Tertiary extensional deformation. Lipman and Sawyer (1985) identified as many as seven Cretaceous caldera fragments in southern Arizona, as well as pieces of Cretaceous volcanoes in more than a half-dozen other mountain ranges in southern Arizona.

These mem- bers represent shallow marine facies of a major marine transgressive-regressive event that reached the Bisbee basin, except for the Rancho Bu- falo Member which is a tongue of the fluvial Morita Formation that underlies the Mural Formation. The facies, succession and regional correlation of its members indicate that deposition of the Mural Formation occurred in northern Sonora on a broad carbonate shelf, the Sonoran shelf, where depositional environments varied from restricted shelf with local terrigenous deltaic and fluvial influence to open shelf with coral- rudist buildups, to offshore shelf.
