Title: Mapping surficial deposits and weathered rock materials of Quaternary age in Colorado, from the continental divide to the Great Plains Author: Moore, David W; Straub, Arthur W; Baker, Michael L Affiliation: U. S. Geological Survey, Denver, CO, United States (USA) Monograph Title: Geological Society of America, 1999 annual meeting Conference: Geological Society of America, 1999 annual meeting, Denver, CO, United States, Oct. 25-28, 1999 Sponsor: USGSOP, Non-USGS publications with USGS authors Source: Abstracts with Programs - Geological Society of America, vol.31, no.7, pp.408-409, 1999 Fifty-nine types of Quaternary surficial deposits and residua were mapped on the Denver and Pueblo 1X2-deg quadrangles, a 14,900 sq. mi. (38,590 sq. km) area where 2.4 million people live, making it the most populous part of Colorado. The maps are being prepared in e00 and .pdf formats, and will be USGS digital and print-on-demand paper maps. ... The quadrangles are part of the nearly finished 4X6-deg Pikes Peak quadrangle of the USGS I-Map series, Quaternary Atlas of the U.S. About 100 map units on the latter are detailed in the way outlined above. Published large-scale geologic maps, USDA soils maps, topical papers, and drill hole data were used to compile information. From soils maps we obtained data about texture, composition, depth to bedrock, basic chemistry (alkalinity, calcium carbonate, gypsum, and salinity), and other characteristics such as hardness and plasticity of parent materials, which help describe surficial deposits and weathered rock materials. --Christopher JJ Thiry Map Librarian Colorado School of Mines 1400 Illinois PO Box 4029 Golden, CO 80401-0029 voice: 303-273-3697 fax: 303-273-3199 [log in to unmask] http://www.mines.edu/library/maproom/ http://www.mines.edu/fs_home/cthiry/ -- ~
