Memoir 38Geology and mineral technology of the Grants uranium region 1979
Compiled by C. A. Rautman in cooperation with 83 authors, 1980, 400 pp., 66 tables, 483 figs.
The continued expansion of national energy programs has resulted in new growth and exploration in the Grants uranium region. This volume includes 45 papers and expanded papers plus four abstracts, all given at the 1979 Grants Uranium Symposium, Albuquerque, New Mexico.
The first "Symposium on the Geology of the Grants Uranium Region" was held as a field conference sponsored by the Society of Economic Geologists in 1961. One of the Lasting results of this conference was the 1963 publication of New Mexico Bureau of Mines and Mineral Resources Memoir 15. Through the years since 1963, this volume has remained an authoritative reference to the geology of this prolific mineral belt in northwestern New Mexico. Despite the continuing usefulness of Memoir 15, the tremendous development of the Grants mineral belt since 1963 has resulted in an expansion both of ore reserves and of our knowledge of the deposits. By the mid-1970s, many people working in the area felt that a revision of Memoir 15 was needed. Late in 1977, a decision was made to convene a new conference and to solicit papers from geologists working in the area.
The response to the call for papers was extremely gratifying. Geologists from across the country rose to the occasion, and, despite full-time duties elsewhere, submitted literally dozens of papers. Contributing authors represented all facets of geologic endeavor: industry, government, academic institutions, and private individuals. The symposium attracted over 800 geologists and other scientists, including representatives from six foreign countries. Forty-six papers were presented at the 1979 symposium. The present volume comprises these papers plus an additional three. The papers cover the broad spectrum of Grants region geology, including discussions of exploration history and methods, individual deposits and regional phenomena, and petrographic investigations and field studies. More peripheral but vitally related topics such as severance taxes, ground-water hydrology, and experimental studies also are included. Although no attempt has been made to compile a total synthesis of knowledge in the Grants uranium region, the hope is that this memoir may serve as a reference work to the region for many years to come.
