Geologic Structure and Occurrence of Gas in Part of Southwestern New York: Part 2. Subsurface Structure in Part of Southwestern New York and Mode of Occurrence of Gas in the Medina Group

Description: Abstract: Based on the records of several hundred deep wells, contour maps have been prepared showing the monoclinal structure of part of western New York, and isopach lines have been drawn showing the westward convergence of the rocks. The mode of occurrence of natural gas in the Medina group is briefly discussed. The location of the gas fields has not been determined by structural traps, but rather stratigraphy and lithology are the controlling factors in trapping the gas, which occurs in por… more

Nickel-gold deposit near Mount Vernon, Skagit County, Washington

Description: From Introduction: "The Mount Vernon nickel-gold deposit is 4 1/2 miles southeast of the city of Mount Vernon, Skagit County, Wash. The writers believe that the nickel was originally present in the serpentinized peridotite and that it was dissolved and redistributed by ascending hydrothermal gold-bearing solutions while the serpentine was being altered into the silica-carbonate rock."

Superposition in the Interpretation of Two-Layer Earth-Resistivity Curves

Description: From abstract: A method is presented for the interpretation of data on electrical resistivity by the superposition of standard reference curves on those obtained from field observations. This method is applicable where bedrock whose average resistivity is essentially uniform is overlain by overburden whose average resistivity is also uniform but markedly distinct.

Tungsten Deposits in the Sierra Nevada Near Bishop, California: A Preliminary Report

Description: From abstract: Scheelite ore bodies occur at widely separated localities in the Sierra Nevada near Bishop, Calif. The scheelite is found in altered sedimentary rocks at or near the contact between granitic rocks and limestones that are partly changed to silicate rocks composed largely of garnet. Mineralization was closely connected with the intrusion of the granite, the latest of the varied intrusives that make up the rocks of the Sierra Nevada.
