Search for geothermal seismic noise in the East Mesa area, Imperial Valley, California
Hariharaiyer Mahadeva Iyer
1974, Open-File Report 74-96
The U. S. Geological Survey made seismic noise measurements in the East Mesa area of Imperial Valley, California, to find out if a noise anomaly was associated with the Mesa thermal anomaly. Thirty-three locations were occupied in the area using slow-speed tape-recording seismic systems. One of the stations (CEN) was...
The diorite at West Warren, south-central Massachusetts
John S. Pomeroy
1974, Open-File Report 74-138
Follated, syntectonic, concordant intrusive bodies of mostly diorite and meladiorite with less abundant quartz diorite and norite have been mapped in the West Warren area of south-central Massachusetts. The rocks of the pluton range from a medium colored phase of diorite and quartz diorite to a dark colored phase of...
Map showing distribution of copper, lead, zinc, mercury, and arsenic in the sediments off the coast of northern Alaska
Peter Barnes, Kam Leong, Charles Gustafson
1974, Miscellaneous Field Studies Map 614
A developing interest in the normal distributions of potentially harmful substances in the natural environment has prompted a baseline study of a virtually pristine region along the northern coast of Alaska. The information reported here outlines the background values of copper, lead, zinc, cadmium, mercury, and arsenic in the nearshore...
Hydrologic Unit Map -- 1974, State of Pennsylvania
Water Resources Division, U.S. Geological Survey
1974, Hydrologic Unit 39
This map and accompanying table show Hydrologic Units that are basically hydrographic in nature.  The Cataloging Units shown will supplant the Cataloging Units previously used by the U.S. Geological Survey in its Catalog of Information on Water Data (1966-72).  The previous U.S. Geological Survey Catalog-Indexing System was by map number...

A preliminary report on a zone containing thick lignite beds, Denver Basin, Colorado
Paul E. Soister
1974, Open-File Report 74-27
A zone of lignite beds of Paleocene age in the Denver Formation (Upper Cretaceous and Paleocene) lies about 800-1,500 feet above the well-known and extensively mined coal beds of the Laramie Formation (Upper Cretaceous). The zone is a few hundred to as much as 500 feet thick. Where lignite beds...
Gravel resources, urbanization, and future land use, Front Range Urban Corridor, Colorado
James M. Soule, Harold R. Fitch
1974, Open-File Report 74-178
An assessment of gravel needs in Front Range Urban Corridor markets to 2000 A.D., based on forecast population increases and urbanization, indicates that adequate resources to meet anticipated needs are potentially available, if future land use does not preclude their extraction. Because of urban encroachment onto gravel-bearing lands, this basic...
