“…The Santa Rosa Formation rests disconformably on the Anton Chico Member in the Lamy area. It is as much as 140 m thick, and the three members recognized by Lucas and Hunt (1987; also see Gorman and Robeck, 1946) in Guadalupe County can also be identified in the Lamy area: basal, sandstone-dominated Tecolotito Member (as much as 61 m thick), medial, mudstone-dominated Los Esteros Member (as much as 47 m thick), and upper, sandstonedominated Tres Lagunas Member (as much as 62 m thick) (Hock, 1970;Johnson, 1973;Allen and Lucas, 1988;Hunt and Lucas, 1988).…”

This volume contains 10 field guides to trips scheduled to take place before, during, and after the joint annual meeting of the GSA Rocky Mountain and South-Central Sections in Albuquerque, New Mexico, on 21-24 April 1991. Most of the field guides combine road logs and technical papers, but Geomorphic and neotectonic evolution along the margin of the Colorado Plateau and Rio Grande rift, northern New Mexico, by Gonzalez and Dethier, is a technical paper with field-trip stops and topics of discussion only briefly listed in an appendix. The detailed road log to this paper is Open file Report no. 374, available from the New Mexico Bureau of Mines & Mineral Resources, Socorro, New Mexico 87801, tel. ( 505) 835-5147.The field guides are arranged in the order in which the trips were announced (GSA News & Information, v. 12, no. 10, October 1990); however, three of those announced are not included. One is Educational geology of the Albuquerque area, a pre-meeting, one-day trip open only to schoolteachers, for which no field guide has been submitted. The other two are post-meeting trips, Geology of the Valles caldera and Jemez volcanic field (one day) and Cenozoic magmatism and tectonics of the southeastern Colorado Plateau, New Mexico (three days), for which field guides have already appeared in the New Mexico Bureau of Mines & Mineral Resources Memoir 46 (1989), and the field-trip participants thus can be supplied with reprints from that publication.Fifty-five authors have contributed to the volume. Because of the large number of authors, their geographic separation, and the short time from submittal to publication (two field guides were made available to us only in mid-February!), it has not been possible to completely standardize the format and to improve on the quality of some of the figures and tables. However, we have done everything possible to turn out a good-quality publication, and we hope our effort will be viewed with the understanding that we had to work fast.We would like to take this opportunity to thank the authors for their contributions and the University of New Mexico Printing Services for an outstanding performance in all phases of production of this volume.

“…Chemical analyses of the asphalt indicate a dominance of marine over terrestrial kerogens, and carbon isotopes are suggestive of either a Permian or Pennsylvanian source. The underlying limestones of the San Andres Formation (Permian) have long been considered to be a source of the asphalt (Gorman and Robeck, 1946;Budding, 1980). However, San Andres source facies in the area are thin, organically lean, and thermally immature in the areas around the tar sands, but deeper, thermally mature, organic-rich shales in the Pennsylvanian section could provide the oil source (Broadhead, 2001a, d;.…”

“…These same faults acted as the conduits for the magmas that form a Tertiary-age basaltic dike that crops out one mile northeast of and downdip of the tar sand deposit. The Santa Rosa tar sands were quarried as a source of road-surfacing material from 1930 until 1939 (Winchester, 1933;Gorman and Robeck, 1946). Santa Rosa Lake was formed when Los Esteros dam was built on the Pecos River in 1980 and the lake now covers the tar sand deposit, rendering further development inopportune.…”
