Reconnaissance Geology of the State of Baja California

Reconnaissance Geology of the State of Baja California

This map was compiled in 1971 at a scale of 1:250,000 by the students and staff of Iniversidad Autonoma de Baja California and San Diego State University. It was published in 1975 as part of the Geological Society of America Memoir 140. Later in 2003 these maps were made available digitally in the GSA special paper Tectonic Evolution of Northwestern Mexico and the Southwestern United States. This volume was assembled as a dedication to the career achievements of R. Gordon Gastil. The papers focus primarily on the Mesozoic and Tertiary tectonic evolution of Baja California and nearby regions of mainland México and southern California. The volume begins with an extensive tectonic overview with the goals pf summarizing our present understanding of the geology of Baja California, addressing several controversial issues and providing a framework for more detailed discussions in some of the remaining papers. The volume contains a wealth of modern analytical data and authoritatively explores regional issues. The publications accompanying CD-ROM contained valuable geochronological and geochemical data, color images, and out-of-print Geological Society of America maps. In particular, the CD-ROM contains the highly sought after geologic maps of northern Baja California published by Gordon Gastil and colleagues in 1975 as part of the Geological Society of America Memoir 140, Reconnaissance Geology of the State of Baja California.
