Paleozoic metasediments in the northern Ruby Mountains, Nevada Paleozoic metasediments in the northern Ruby Mountains, Nevada
New evidence indicates that high-grade regionally metamorphosed marble and quartzite in the northern Ruby Mountains are Paleozoic strata. Correlation is based on a match of the lithologic sequence to strata of Cambrian to Devonian age in nearby areas; particularly diagnostic is a brown dolomite at the base of the Cambrian carbonate sequence. The metamorphic complex contrasts with...

Geologic map of Late Cenozoic deposits, Santa Clara County, California Geologic map of Late Cenozoic deposits, Santa Clara County, California
This map is the first of several in the San Francisco Bay region showing the distribution and differentiation of the late Cenozoic alluvial, estuarine, and volcanic deposits. The sedimentary deposits of gravel, sand, silt, and clay were separated into geologic map units on the basis of their post-depositional soil development, texture, and geomorphology. Some of the geologic units are...

Petroleum possibilities of Yukon-Koyukuk Province, Alaska: region 1 Petroleum possibilities of Yukon-Koyukuk Province, Alaska: region 1
The Yukon-Koyukuk province covers 100,000 sq mi (259,000 sq km) along the west coast of Alaska, extending from the Brooks Range to the Yukon delta, but excluding the Seward Peninsula. It is essentially a vast tract of Cretaceous rocks locally veneered by Quaternary alluviated beds and volcanic rocks. The Cretaceous section contains a large volume of volcanic rocks, and most of the...

Petroleum possibilities of the Yukon-Koyukuk Province, Alaska Petroleum possibilities of the Yukon-Koyukuk Province, Alaska
The recent discovery of major oil resources on Alaska's North Slope has rekindled interest in the petroleum possibilities of the Yukon-Koyukuk province, a vast tract of Cretaceous rocks stretching along the west coast of Alaska from the Brooks Range to the Yukon delta. Attention was first focused on this region in the early 1950's, after oil and gas were discovered in the Cretaceous of...

Biostratigraphy and dolomite porosity trends of the Lisburne Group Biostratigraphy and dolomite porosity trends of the Lisburne Group
This preliminary study is based on measured and carefully collected sections of the Lisburne Group (fig. 1, sees. 1-29). The outcrops extend from Cape Lisburne (sec. 1) in the west to Egaksrak River (sec. 29) in northeastern Alaska and are used as the basic building blocks for the carbonate facies maps and the cross section. Lithologic and foraminifera samples were collected at 10-foot...
