Field trip no. 6 from “Geologic Excursions to the Rocky Mountains and Beyond,” field trip guidebook of the 1996 Annual Meeting of the Geological Society of America. (SP-44 has the complete set.) 28 pages. Digital PDF download. OF-96-04-06D

From the Introduction:

Proterozoic anorthosites and related rocks are well exposed in the high prairie and open canyons of the Laramie Mountains of southeastern Wyoming, an anticlinal foreland uplift that was formed during the late Cretaceous-Paleocene Laramide Orogeny. Because these rocks have been unaffected by later penetrative metamorphism and because of the accessibility of this area, the Laramie Mountains are one of the best places in the world in which to study the origin and evolution of massif anorthosites. Under the funding of the U.S. National Science Foundation, members of the faculty and students of the University of Wyoming and the State University of New York at Stony Brook have been mapping and studying the Laramie Anorthosite Complex (LAC) since 1981. This paper summarizes most of their important findings.
