This book was released on 1968 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 4,210 feet of Late Cretaceous and 1,440 feet of Tertiary sedimentary rocks are exposed in the Salt Wells Anticline area of southcentral Sweetwater County, Wyoming. Late Cretaceous units include the Blair, Rock Springs, Ericson, and Almond Formations of the Mesaverde Group and the Lewis Shale; Tertiary units include the Paleocene Fort Union and the Eocene Wasatch Formations, and the Oligocene or Miocene Bishop Conglomerate. Alluvium, terrace gravels, and landslide debris are the most extensive Quaternary deposits. The Late Cretaceous rocks of the Rock Springs Uplift exhibit intricate intertonguing of marine and nonmarine facies, and they record the eastward regression of the Late Cretaceous sea. Intertonguing of environments in the region resulted from 1) deposition in a subsiding basin of detritus episodically shed from Laramide source areas to the west and northwest, and 2) periodic pulses of basin subsidence. Rocks of the Blair and Rock Springs Formations record marine depositional environments. Regressive littoral sandstones are found at the base and top of the Blair Formation and at the top of the Rock Springs Formation. Eastward encroachment of fluviatile deposits is marked by deposition of the Ericson and lower Almond Formations. Northerly coarsening of sandstones and southeasterly current directions in the Ericson indicate that the Wind River Mountains area was one probable source area. A second, more westerly source area is indicated by conglomerate lenses and easterly current directions in the upper Ericson Formation and by the thick sequence of continental deposits in the lower Almond Formation. Return of marine conditions is recorded by the transgressive marine deposits of the upper Almond Formation and the offshore marine shales and mudstones of the Lewis Shale. The latest Cretaceous rocks exposed on the Uplift record the final regression of the Cretaceous sea. The Cretaceous period ended with uplift of the Rock Springs area. The continental deposits of the Paleocene Fort Union Formation were deposited unconformably along the flanks of the Uplift; in turn, this formation is conformably overlain by the fluviatile red bed deposits of the Eocene Wasatch Formation. Contemporaneously with the deformation of the Uinta Mountains, the Salt Wells folds were superimposed on the southern part of the Uplift. During Oligocene or Miocene the Uplift was truncated by the Gilbert Peak pediment surface. Quaternary fluvial erosion has deeply dissected the Rock Springs Uplift.

Download or read book Origin and Distribution of Six Heavy mineral Placer Deposits in Coastal marine Sandstones in the Upper Cretaceous McCourt Sandstone Tongue of the Rock Springs Formation Southwest Wyoming written by Henry W. Roehler and published by . This book was released on 1989 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geology of six geographically separated but geneti- cally related heavy-mineral placer deposits are investigated along 40 miles of coastal-marine sandstone outcrops comprising the McCourt Sandstone Tongue. The heavy- mineral placer deposits consist of dark-brown to black, fine- to medium-grained, ferruginous sandstones that occur in elongated lenses that are as much as 6.6 ft thick and 2,000 ft long. The placer deposits are mostly intercalated with light-gray or tan quartzose shoreline sandstones that offlapped southeastward across the study area and formed a strand plain during a regression of the interior Cretaceous sea. The placers were deposited along a single shoreline during one stage of the regression. The heavy-mineral placer deposits are composed of about 85 percent opaque iron minerals, mostly magnetite, hematite, and ilmenite, and about 15 percent nonopaque minerals, mostly zircon, with minor amounts of tourmaline, rutile, garnet, sphene, hornblende, apatite, and traces of other minerals. The depositional settings are river mouth, berm, forebeach, surf, and middle shoreface, where the segregation of light and heavy minerals took place by fluvial, marine, and eolian processes. A plutonic source for most of the heavy minerals was probably the Sevier orogenic belt located 150-250 miles west of the study area. The heavy-mineral deposits in the McCourt Tongue are analogous in origin to that of heavy-mineral deposits that are presently forming along the southeast Atlantic and gulf coasts of the United States.
