| Summary: | Below this is the Sand Unit, a thin quartz-rich channel sand characterization of the Texas A&M University NGES sites. characterized sand and clay areas. The geologic history in colored Clay Unit. Sediments of this unit are overbank consists of a mix of clay, sand and clayey gravel layers. create a three dimensional view of the sediments at each crossbedded fine grained sand containing little to no clay; deposited as alluvium when river flow was at a higher level deposits which underwent a high degree of soil development. engineering by allowing multi-user access to well geologic histories. The upper units at the sites are in conjunction with existing geotechnical information to lowest unit, the Spiller Member, is an olive green, laminated of mottled, red and tan colored, overbank deposits with Pleistocene aged terrace deposits of the Brazos River, Pleistocene units at the Sand Site: the Silty Sand consisting Riverside Campus in Brazos County, Texas are part of a joint shale with interbedded fine-grained sands. There are three shales which are defined geotechnically as a clay soil. The site. Both the Sand Site and the Clay Site have similar Spiller Member of the Crockett Formation. Spiller Member of the Crockett Formation. The Pleistocene than the modem river valley. The terrace deposits lie that grades from fine sand to gravel. The third and fourth The deepest unit is the laminated shale of the Eocene aged the Mix Unit, deposited by a fluctuating energy stream which The National Geotechnical Experimentation Sites (NGES) the National Science Foundation. The NGES sites were created this report will contribute to the background Three geological borings were drilled at each site and used to accelerate research in geotechnical and geo-environmental TXAMSAND and TXAMCLAY research sites, located on Texas A&M unconformably on nearshore marine deposits of the Eocene aged units at the Clay Site are part of the Spiller Member. The units at the Clay Site consist of a mottled red and grey Upper Spiller Geotechnical Unit consists of dark grey clay varying degrees of silt/clay content; the Clean Sand Unit, a venture sponsored by the Federal Highway Administration and |
