Introduction to stratigraphy and hydrocarbon occurrence in Oligocene and Miocene rocks of the Santa Barbara-Ventura and Santa Maria Basins of California
The Santa Barbara-Ventura and Santa Maria basins of southern California have been of great interest to the oil industry because oil or gas has been produced from nearly all the sedimentary units ranging in age from the Cretaceous to the Pleistocene. In particular, the Neogene section of these basins is oil-rich, containing eight giant oil fields (greater than 100 million barrels) in the onshore an

A spectral reflectance study (0.4-2.5 μm) of selected playa evaporite mineral deposits and related geochemical processes
Playa evaporite mineral deposits show major compositional variations related to differences in lithology, hydrology, and groundwater geochemistry. The use of visible and near-infrared (VNIR) spectral reflectance measurements as a technique for investigating the mineralogy of playa efflorescent crusts is examined. Samples of efflorescent crust were collected from 4 playa: Bristol Dry Lake, Saline V

Acoustic Doppler discharge-measurement system
A discharge-measurement system that uses a vessel-mounted acoustic Doppler current profiler has been developed and tested by the U.S. Geological Survey. Discharge measurements using the system require a fraction of the time needed for conventional current-meter discharge measurements and do not require shore-based navigational aids or tag lines for positioning the vessel.

Arsenopyrite in the bank deposits of the Whitewood Creek-Belle Fourche-Cheyenne River-Lake Oahe system, South Dakota, U.S.A.
Mining, milling, and processing wastes containing quantities of arsenopyrite were produced around Lead, South Dokata, from 1875 to 1977. Much of this material was discharged into Whitewood Creek, and from there portions of the waste were transported to the Belle Fourche River, thence to the Cheyenne River, and finally to the Missouri River. In 1958, the Missouri River was dammed at Pierre, forming
