“…Unit grades upwards to volcaniclastic rocks (Xdt) and is interlayered with mappable units of felsic to intermediate volcanic rocks (Xiv and Xdt). Unit includes Coyote greenstone and Isleta greenstone of Cavin (1985) and the lower part of Tijeras greenstone of Connolly (1981).…”

“…To the northeast, the Tijeras fault juxtaposes Precambrian rocks of contrasting lithologies (Fig. 2) (Connolly, 1982) for nearly 10 km, with greenstone and associated rocks on the southeast (Bruns, 1959) and quartzofeldspathic gneiss on the northwest (Lodewick, 1960). In the Tijeras mining district, the greenstone hosts ore deposits that are interpreted as Precambrian syngenetic mineralization remobilized during later episodes of metamorphism and deformation (Fulp et al, 1982).…”

“…Tijeras Canyon, Sandia Mountains, and Tijeras graben Lee A. Woodward Tijeras Canyon is underlain by the Tijeras fault which strikes northeast and separates two Proterozoic metamorphic terranes of contrasting rock types and structural styles (Connolly, 1981(Connolly, , 1982. The Tijeras fault has undergone at least four episodes of movement, during the Precambrian, Pennsylvanian, Tertiary, and Quaternary (Lisenbee et al, 1979).…”

“…The Tijeras fault has undergone at least four episodes of movement, during the Precambrian, Pennsylvanian, Tertiary, and Quaternary (Lisenbee et al, 1979). Although the fault may have had different directions of slip during the various episodes of movement, it seems likely that the cumulative sense of motion in Tijeras Canyon consists of several kilometers of left-slip as judged from contrasts in lithology, structural geometry, and metamorphic history (Connolly, 1982).…”

“…Minor felsic metavolcanic rocks are also present. Both the Cibola gneiss and Tijeras greenstone were isoclinally folded during amphibolite-facies metamorphism, but the greenstone was tightly refolded about axes nearly parallel to the older fold axes, whereas the gneiss was refolded about axes at a high angle to the earlier fold axes (Connolly, 1982).…”

Field guide to geologic excursions in New Mexico and adjacent areas of Texas and Colorado

1991

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.
