Sedimentary features of the Blackhawk formation (Cretaceous) at Sunnyside, Carbon County, Utah
John O. Maberry
1968, Open-File Report 68-170
The Blackhawk Formation at Sunnyside, Utah, was deposited along the western margin of the Western Interior Cretaceous sea during southeastward withdrawal of the sea. Sand was the dominant type of land-derived sediment deposited in the Sunnyside district during the regressive phases. Sand bodies prograded seaward in response to changing sediment...

Bruce E. Kilpatrick
1968, Open-File Report 68-157
The Wanamu-Blue Mountains area is situated in the Northwest District of Guyana, about 110 miles northwest of Georgetown. The Blue Mountains are low, but rugged, hills that have developed on mafic metamorphic rocks that occur in an arcuate "mantle" around a granite batholith, the Aranka-Wanamu Granite. The area lies within...

A mineral reconnaissance of the Jabal Khida quadrangle, Saudi Arabia
Jesse William Whitlow
1968, Open-File Report 68-325
Reconnaissance of the Jabal Khida quadrangle shows that granite and granodiorite (unit gg), biotite and hornblende granite (unit gr) and alkalic and paralkalic granit (unit gp) divisions for granites seems valid, but that two ages of metamorphic and extrusive rocks are mapped as the Halaben formation (unit ha/hc). Semiquantitative analyses of...

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...
Ground-water exploration using the resistivity method on the Hawaiian Islands of Oahu and Hawaii
Adel A. R. Zohdy, Dallas B. Jackson
1968, Open-File Report 68-341
Thirty-six resistivity soundings were made on the islands of Oahu and Hawaii to determine the applicability of galvanic resistivity methods for locating fresh-water aquifers in the State of Hawaii. Soundings were made on the northwestern part of the island of Oahu near the town of Waialua and on the island...
