Preliminary Isostatic Residual Gravity Map of the Tremonton 30' x 60' Quadrangle, Box Elder & Cache Counties, Utah, and Franklin & Oneida Counties, Idaho

By: V.E. Langenheim, R.Q. Oaks, H. Willis, A.I. Hiscock, B.A. Chuchel, J. Rosario, and C.L. Hardwick

A new isostatic residual gravity map of the Tremonton 30′ x 60′ quadrangle of Utah is based on compilation of preexisting data and new data collected by the Utah and U.S. Geological Surveys. Pronounced gravity lows occur over North Bay, northwest of Brigham City, and Malad and Blue Creek Valleys, indicating significant thickness of low-density Tertiary sedimentary rocks and deposits. Gravity highs coincide with exposures of dense pre-Cenozoic rocks in the Promontory, Clarkston, and Wellsville Mountains. The highest gravity values are located in southern Curlew Valley and may be produced in part by deeper crustal density variations or crustal thinning. Steep gradients also coincide with the margins of the Promontory Mountains, Little Mountain, West Hills, and the eastern margin of the North Promontory Mountains and may define concealed basin-bounding faults.

Hundreds Of Earthquakes Shake Idaho, Rattling Nerves And Puzzling Geologists

huffingtonpost.com

Hundreds of low-level and medium-sized earthquakes have struck central Idaho since last month, puzzling geologists who wonder whether the ruptures portend a much larger temblor to come or are merely the rumblings of a seismic fault previously thought to be dormant.

Geologic map of the Johnson Lakes quadrangle, Kane County, Utah, and Coconino County, Arizona,

By: Janice M. Hayden

The Johnson Lakes quadrangle includes parts of the Chocolate (Shinarump) and Vermilion Cliff steps of the Grand Staircase in the southwest part of Grand Staircase-Escalante National Monument. Reddish-brown Lower Jurassic strata of the Vermilion Cliffs dominate the map area. Overall, strata dip gently to the northwest. They are cut by the Paunsaugunt fault at the east edge of the map area, and by several minor, mostly down-to-the-west normal faults. A variety of surficial deposits locally conceal bedrock, including broad alluvial and eolian surfaces deeply incised by modern arroyos. “Picture stone” from the Shinarump Conglomerate Member of the Chinle Formation is quarried locally.

This CD contains geographic information system (GIS) files in ESRI file geodatabase and shapefile formats. Also included are two plates-the geologic map at 1:24,000 and the explanation sheet-both in PDF format. The latest version of Adobe Reader is required to view the PDF files. Specialized GIS software is required to use the GIS files.

Hydrogeochemistry, geothermometry, and structural setting of Thermal Springs in northern Utah and southeastern Idaho,

By:Brennan Young, Katherine, Shervais, Moises Ponce-Zepeda, Sari Rosove, James Evans

This CD contains a 29-page report conducted by undergraduate researchers at Utah State University during 2010 and 2011 under the direction of Dr. James P. Evans. It includes data collected from hot springs in northern Utah and southeastern Idaho, including location, temperature, acidity, salinity, cation concentrations, and maximum reservoir temperature estimates acquired through the application of several cation geothermometers.
