Self-calibrating seismic amplifier and telemetry system
John R. Van Schaack
1975, Open-File Report 75-64
A frequency modulated, constant bandwidth, telemetry system has been designed to transmit simultaneously up to 8 channels of seismograph data from remote locations to a central recording site via radio or voice-grade telephone circuit. By utilizing state-of-the-art integrated circuits, the size of the remote unit has been considerably reduced over...

Ground-water availability in the Belcourt area, Rolette County, North Dakota
P.G. Randich
1975, Open-File Report 75-104
Test drilling and geologic data indicate that there are two potential aquifers in the Belcourt, N. Dak. area capable of supplying a sufficient quantity of ground water for the city of Belcourt. The Fox Hills aquifer, located about 3 miles (4.8 kilometres) west of Belcourt, could yield a sufficient quantity,...

A geologic analysis of the Side-Looking Airborne Radar imagery of southern New England
Paul T. Banks
1975, Open-File Report 75-207
Analysis of the side looking airborn radar imagery of Massachusetts, Connecticut and Rhode Island indicates that radar shows the topography in great detail. Since bedrock geologic features are frequently expressed in the topography the radar lends itself to geologic interpretation. The radar was studied by comparisons with field mapped geologic...

1975, Open-File Report 75-36
Sphene and rutile are characteristic accessory minerals of blueschist facies metamorphic rocks. However, only sphene is present in the lowerr grade blueschist assemblages. In many areas of the world these blueschists pass into, or are in fault contact with, higher grade glaucophane schists, rutile-bearing amphibolites, and eclogites. The origin of...
