Distribution of beryllium, tin, and tungsten in the Lake George area, Colorado
C. C. Hawley, Wallace R. Griffitts
1968, Circular 597
Complex ore deposits are spatially associated with granitic bodies of Precambrian age in the Lake George area, Colorado. They include greisens that contain high concentrations of beryllium and subordinate amounts of tin, tungsten, and other metals associated with the Redskin Granite. Scheelite deposits in calc-silicate rocks and greisen deposits near Tappan Mountain...
Preliminary interpretation of a seismic-refraction profile across the Large Aperture Seismic Array, Montana
C.A. Borcherdt, John C. Roller
1968, Open-File Report 68-15
A reversed seismic-refraction profile extending northeastward from Greycliff, Montana, across the Large Aperture Seismic Array (LASA) to Charleson, North Dakota, indicates that the crust of the earth consists of two layers with P-wave velocities of 6.1 km/sec and 6.7 km/sec, and that the upper-mantle velocity is 8.3 km/sec. The Mohorovicic...
Carbonate rocks of Cambrian and Ordovician age in the Lancaster quadrangle, Pennsylvania
Harold Meisler, Albert E. Becher
1968, Bulletin 1254-G
Detailed mapping has shown that the carbonate rocks of Cambrian and Ordovician age in the Lancaster quadrangle, Pennsylvania, can be divided into 14 rock-stratigraphic units. These units are defined primarily by their relative proportions of limestone and dolomite. The oldest units, the Vintage, Kinzers, and Ledger Formations of Cambrian age,...
Progress report, 1966-1967: Water study - Greater Anchorage area, Alaska

1968, Open-File Report 68-6
The purpose of the 5-year cooperative water resources study of the Greater Anchorage area by the Geological Survey is to appraise the water resources of the area and obtain data needed to solve water problems and to assist in the orderly development and management of the resource....
Geology and ground-water resources of the Deer Lodge Valley, Montana
Richard L. Konizeski, R. G. McMurtrey, Alex Brietkrietz
1968, Water Supply Paper 1862
The Deer Lodge Valley is a basin trending north-south within Powell, Deer Lodge, and Silver Bow Counties in west-central Montana, near the center of the Northern Rocky Mountains physiographic province. It trends northward between a group of relatively low, rounded mountains to the east and the higher, more rugged Flint...
