UGS completed a geologic map of the Rush Valley 30' x 60' quadrangle at 1:62,500 scale. The quadrangle lies on the fringe of the Salt Lake City metropolitan area with land use varied between public, military, Indian reservation, and private. The mapping is needed for proper management of land, water, and other economic resources. The map area lies within the eastern Basin and Range Province. Ranges are composed of unexposed basement rocks overlain by exposed Neoproterozoic through Triassic rocks about 10.4 miles (16.8 km) thick, and numerous Tertiary sedimentary and volcanic units (~47 to 20 Ma). The intervening valleys include bedrock covered with Miocene-Pliocene? rocks (~11 to 4 Ma) and Tertiary-Quaternary surficial deposits. The map area is on the south flank of the Uinta-Tooele structural zone. The quadrangle lies in the Charleston-Nebo (Provo) salient of the Sevier fold-thrust belt with some thrust faults exposed, but the overall geometry obscured by extensive valley fill and later faulting. Following Sevier deformation, calk-alkaline volcanism occurred from several Paleogene volcanic centers (42 to 25 Ma). Extensional tectonism created the distinctive basin and range topography from about 20 Ma to the present. Early extensional basin fill includes Miocene sedimentary and volcanic rocks followed by Pliocene-Holocene surficial deposits primarily from lacustrine and alluvial depositional environments. Valley areas were covered by late Pleistocene Lake Bonneville, and deposits are associated with three levels of regional shorelines. Normal faults cut the ranges and are known to bound some valley margins where not concealed. Although deep drill hole data are relatively sparse, gravity data were used to help constrain basin geometries.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "summary": "This geographic information system (GIS) release of the geologic map of the Rush Valley 30' x 60' quadrangle, Tooele, Utah, and Salt Lake Counties, Utah, provides basic geologic data in digital format for government, academic, private industry, and public users.", "title": "RushValley30x60_CrossSectionLines", "tags": [ "geologic map", "GIS", "geology", "geologic units", "geologic formations", "fold axes", "contacts", "faults", "synclines", "anticlines", "monoclines", "Lake Bonneville shorelines", "geoscientific information", "Utah", "Tooele County", "Utah County", "Salt Lake County", "Dugway Proving Ground", "Tooele Army Depot", "Camp Williams", "Rush Valley" ], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": 150000000, "maxScale": 5000, "spatialReference": "", "accessInformation": "Program Manager: Stefan M.
