Effects of Alterations to Low Gradient Reaches of Utah Streams

Description: This report describes an investigation of the effects of stream channelization on fish and macro-invertebrates in low gradient reaches of Blacksmith Fork River and the Logan River in the floodplain of Cache Valley in northern Utah. Channelization adversely affected both fish and macro-invertebrate populations and biomass, with the severity of impact directly related to the amount and duration of disturbance of the physical habitat.

Jurassic (Bathonian and Callovian) Ammonites in Eastern Oregon and Western Idaho

Description: From abstract: Jurassic ammonites of late Bathonian to middle Callovian Age have been found in 12,000-13,000 feet (3,660-3,960 m) of strata exposed in the area near and south of Izee and Seneca in east-central Oregon. Ammonites of early Callovian Age and possibly also late Bathonian Age occur in several hundred feet of black shale exposed along Dennett Creek near Mineral, Idaho. Early Callovian ammonites also occur in similar black shale exposed on the Oregon side of Snake River Canyon about 32 miles (52 km) south of the northeast corner of Oregon.

Fluorspar Deposits Near Meyers Cove, Lemhi County, Idaho

Description: Abstract: The fluorspar deposits near Meyers Cove, Lemhi County, Idaho, are localized along three groups of shear zones: one group strikes northeast and dips steeply northwestward, another strikes northeast and dips gently northwestward, and the third strikes northwest and dips gently southwestward. The country rocks are tuffs and flows of the Casto volcanics of Permian(?) age and the Challis volcanics of late Oligocene or early Miocene age. The known deposits are in a belt about 3 miles long and 2 miles wide and crop out at altitudes between 5,100 feet and 7,200 feet above sea level. The principal vein minerals are fluorite, chalcedony, and barite. The fluorite occurs as lodes, crusts around fragments of rock, and replacements of fine breccia. The lodes range in size from veinlets to vein zones several hundred feet long and as much as 20 feet wide and contain ore that ranges in grade from 40 percent to 85 percent CaF2; the average grade is about 50 percent CaF2.

Application of Field Measurements and Computer Modeling to Evaluate Deep Mine Shaft Stability in Northern Idaho

Description: Abstract: Researchers at the U.S. Bureau of Mines have developed personal-computer-based data acquisition, instrumentation, and mine visualization and modeling techniques to evaluate a mine accessway in a deep hard-rock mine in northern Idaho. These techniques were applied to a mine shaft in a large silver mine that has been in operation for many years. A very deep, rectangular, timber-supported shaft extending to depths exceeding 2.3 km (7,500 ft) had been deforming continuously as a result of nearby mining, resulting in operational problems. Preliminary visual observations and rock and support monitoring confirmed that severe diagonal distortion was occurring. Extensive field measurements and data analysis confirmed initial observations, provided insights into the cause of deformation, and defined a general approach to structural modeling. Computer analysis of the problem was initiated by developing a three-dimensional model of the terrain. This represented a volume of rock approximately 80 km3 (40 x 1010 ft) and an area on the surface surrounding the mine 9 km2 (3 square miles). Based on this model, a three-dimensional, finiteelement analysis was conducted to establish boundary conditions for sequentially more detailed two- and three-dimensional submodels of the shaft area. Results from the computer study are being used to develop new approaches to mine design and to provide design guidelines for deep mine accessways subject to severe rock-mass loading conditions.

Preliminary Report on the Mineral Hill Monazite Deposits, Lemhi County, Idaho

Description: From abstract: The Mineral Hill monazite deposits, 3 to 5 miles northeast of the town of Shoup, Lemhi County, Idaho, were investigated by the U. S. Geological Survey in July 1952. The deposits are replacement veins and lenses along shears in a pendant, principally of pre-Cambrian biotite gniess, about 4 to 5 miles in size and enclosed by granite of the Idaho batholith. The veins consist predominantly of calcite, monazite, and allanite, and contain minor quantities of barite, magnetite, rutile, and apatite.

Geology of the Murray Area, Shoshone County, Idaho

Description: Abstract: The Murray area includes almost the whole drainage basins of Prichard, Eagle, and Beaver Creeks and is underlain by the pre-Cambrian Belt series which is subdivided, from oldest to youngest, as follows: Prichard formation (upper and lower parts), Burke formation, Revett quartzite, St. Regis formation, Wallace formation, and Striped Peak formation. The Belt series in this area is cut by many small monzonite stocks believed to be related to the Cretaceous Idaho batholith. This report describes only the lead-zinc mines. The lead-zinc production around Murray reached its peak in 1911 and 1912 when the Monarch, Edith Murray (Pontiac or Terrible Edith), Bear Top, Paragon, Black Horse, and Silver Strike mines were active. Many of these mines have produced ore intermittently since then, and the Jack Waite mine has been very active since about 1930.

Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California

Description: From abstract: A reconnaissance to determine the uranium content of granitic rocks in the western states was made during parts of October and November 1951. The paucity of our knowledge of the granitic rocks that are most likely to contain significant quantities of uranium has prevented all but a very general isolation of areas or types of granitic rocks for reconnaissance examination.

The Garm-Lamoreaux Mine, Lemhi County, Idaho

Description: From abstract: The Garm-Lamoreaux property, Lemhi County, Idaho is known to have uraninite and zippeite on two of its dumps. The property has been explored by five adits, two of which are now caved, and one of which is partly caved. The country rock is schistose micaceous quartzite and argillaceous quartzite of Belt age. An east-west fault cuts the quartzite, and the Lamoreaux vein, a gold-sulfide-quartz veins occurs in the fault. The uranium minerals are believed to have core from the vein, on the now inaccessible No. 3 level.

Reconnaissance Geology of Placer Deposits Containing Radioactive Minerals in the Bear Valley District, Valley County, Idaho

Description: From introduction: The Bear Valley district is situated in southwestern Idaho, in the drainage of the Middle Fork of the Salmon River (see fig. 1). The placer deposits were drilled by the U. S. Bureau of Mines in 1951 and 1952 to determine their content of monazite and "radioactive black minerals" (here referred to loosely as "radioactive blacks"). The purpose of the study outlined here was to provide a geologic background for an understanding of the origin and distribution of the placer minerals.

An Evaluation of Water-Quality Data Obtained at Four Streamflow Daily-Record Stations in Idaho

Description: From introduction: This study is limited to four U.S. Geological Survey stream-flow stations located in Idaho (figure 1). The 6 to 22 years of stations were assembled and evaluated through use of computer techniques for data plotting and regression analysis developed by Steele (1972). Objectives of this evaluation were were (1) to show which parameters were highly correlative with the levels of specific conductance and(or) discharge and (2) to see if any changes in overall chemical character of the stream had occurred over the long term.

Magnitude and Frequency of Floods in Small Drainage Basins in Idaho

Description: Abstract: A method which relates basin characteristics with peak flow characteristics is presented for determining magnitude and frequency of floods on streams with drainage areas between 0.5 and 200 square miles. Regression equations for each of eight regions are presented for determination of the 10-year flood. Peak flows for the 25- and 50-year floods can then be estimated from ratios developed for each region. Regression equations are not developed because of poor definitions for several areas that total about 20,000 square miles. The equations were based on multiple-regression techniques using annual peaks and basin characteristics for 303 gaged sites.
