Reconnaissance geology north of the Hoholitna River, Taylor Mountains D-1 1:63,360-scale quadrangle, southwestern Alaska: A section in Geological studies in Alaska by the U.S. Geological Survey, 1999 Reconnaissance geology north of the Hoholitna River, Taylor Mountains D-1 1:63,360-scale quadrangle, southwestern Alaska: A section in Geological studies in Alaska by the U.S. Geological Survey, 1999
The lower Paleozoic (Silurian and Ordovician) carbonate stratal succession is divided into six unnamed stratigraphic units in the northern part of the Taylor Mountains D-1 1:63,360-scale quadrangle of southwestern Alaska. Several of these units have previously been recognized in the McGrath and Medfra quadrangles to the northeast in strata of the Nixon Fork subterrane of the Farewell...

Use of structural geology in exploration for and mining of sedimentary rock-hosted Au deposits Use of structural geology in exploration for and mining of sedimentary rock-hosted Au deposits
Structural geology is an important component in regional-, district- and orebody-scale exploration and development of sedimentary rock-hosted Au deposits. Identification of timing of important structural events in an ore district allows analysis and classification of fluid conduits and construction of genetic models for ore formation. The most practical uses of structural geology deal...

Preliminary mineralogical characterization of weathered and less-weathered strata of the Meade Peak phosphatic shale member of the Permian Phosphoria Formation: Measured sections C and D, Dry Valley, Caribou County, Idaho Preliminary mineralogical characterization of weathered and less-weathered strata of the Meade Peak phosphatic shale member of the Permian Phosphoria Formation: Measured sections C and D, Dry Valley, Caribou County, Idaho
This study used powder X-ray diffraction, with Rietveld quantification software to quantify and characterize the mineralogy of the 83 samples collected from two stratigraphic sections measured by the U.S. Geological Survey at the Dry Valley mine in the Meade Peak Member of the Phosphoria Formation. Analyses show extensive variability of carbonate substitution in the fluorapatite...

Petrography and physical properties of selected rock types associated with the Hayward Fault, California Petrography and physical properties of selected rock types associated with the Hayward Fault, California
This report provides brief petrographic descriptions of rock samples collected from the vicinity of the Hayward Fault, Northern California. Two groups of rock samples are represented here: A set of six samples that were used for laboratory measurements of P- and S-wave velocity , strength, density, and porosity. This group was examined using standard petrographic microscope, scanning...
