Preliminary potential-field constraints on the geometry of the San Fernando basin, Southern California Preliminary potential-field constraints on the geometry of the San Fernando basin, Southern California
Gravity and magnetic data provide new insights on the structural underpinnings of the San Fernando Basin region, which may be important to ground motion models. Gravity data indicate that a deep basin (>5 km) underlies the northern part of the San Fernando Valley; this deep basin is required to explain the lowest gravity values over the Mission Hills thrust fault. Gravity modeling...

Locations and ages of middle Tertiary volcanic centers in coastal California Locations and ages of middle Tertiary volcanic centers in coastal California
This report includes a map and three tables that summarize available information on the locations and ages of late Oligocene to middle Miocene volcanic centers in coastal California. This information, in turn, provides supporting documentation for a planned formal publication by D.S. Wilson, P.A. McCrory, and R.G. Stanley on the implications of volcanism in coastal California for the...

Publications of the Western Earth Surface Processes Team, 1999 Publications of the Western Earth Surface Processes Team, 1999
The Western Earth Surfaces Processes Team (WESPT) of the U.S. Geological Survey, Geologic Division (USGS, GD), conducts geologic mapping and related topical earth- science studies in the western United States. This work is focused on areas where modern geologic maps and associated earth-science data are needed to address key societal and environmental issues such as ground-water quality...

Minerals in our environment Minerals in our environment
Minerals are found everywhere in our daily lives. This poster depicts numerous items found throughout a home, and the mineral(s) or mineral resources used in the ingredients of, or construction/manufacturing of those items. Designed for K-8 Teachers this poster can be scaled and is printable at 36" x 60" and legible at 11" x 17" in size.

Field estimates of gravity terrain corrections and Y2K-compatible method to convert from gravity readings with multiple base stations to tide- and long-term drift-corrected observations Field estimates of gravity terrain corrections and Y2K-compatible method to convert from gravity readings with multiple base stations to tide- and long-term drift-corrected observations
Gravity observations are directly made or are obtained from other sources by the U.S. Geological Survey in order to prepare maps of the anomalous gravity field and consequently to interpret the subsurface distribution of rock densities and associated lithologic or geologic units. Observations are made in the field with gravity meters at new locations and at reoccupations of previously...
