Mineral potential of selected felsic plutons in the eastern and southeastern Arabian Shield, Kingdom of Saudi Arabia
Edward A. du Bray
1983, Open-File Report 83-370
Sixteen well-defined geochemical anomalies associated with felsic plutons and (or) muscovite-bearing plutons of Proterozoic age have been identified in the eastern and southeastern Arabian Shield. The majority of these plutons are highly evolved, granitophile-element-enriched muscovite-bearing granites that are weakly peraluminous. A followup study of the mineral potential of these plutons included...

Habitat Suitability Index Models: Lewis' woodpecker
Patrick J. Sousa
1983, FWS/OBS 82/10.32
This document is part of the Habitat Suitability Index (HSI) Model Series (FWS/OBS-82/10), which provides habitat information useful for impact assessment and habitat management. Several types of habitat i nformat i on are provided. The Habitat Use Information Section is largely constrained to those data that can be used to...
Geohydrology and model analysis of the stream-aquifer system along the Arkansas River in Kearny and Finney counties, southwestern Kansas
L. E. Dunlap, Richard J. Lindgren, C. G. Sauer
1983, Open-File Report 83-222
A study was made, in cooperation with the Division of Water Resources, Kansas State Board of Agriculture, to determine geohydrologic conditions in an area comprising nearly 850,000 acres along the Arkansas River valley in Kearny and Finney Counties, southwestern Kansas. The Arkansas River meanders atop and interacts hydraulically with the...

The Emma Bell deposit, Siskiyou Co., California: A possible low-grade source of chromite
B. R. Lipin, Nicholas Wetzel, S. M. Heinrich
1983, Open-File Report 83-816
The Emma Bell chromite deposit in Siskiyou County, California contains over 5 million tons of dunite averaging about 4 percent Cr2O3. Chromite is not evenly disseminated throughout the dunite, however. For the most part the deposit consists of many chromite-rich bands in sharp contact with, and separated by, common dunite...
Application of Gauss algorithm and Monte Carlo simulation to the identification of aquifer parameters
Timothy J. Durbin
1983, Open-File Report 81-688
The Gauss optimization technique can be used to identify the parameters of a model of a groundwater system for which the parameter identification problem is formulated as a least squares comparison between the response of the prototype and the response of the model. Unavoidable uncertainty in the true stress on...

Publicly available data on the composition of subsea manganese nodules extend previous reports of differences in average metal contents from ocean to ocean and of variations related to latitude and depth. Pacific Ocean nodules have the highest average manganese, nickel, and copper contents, and Atlantic Ocean nodules have the highest...
Water quality of lakes Faith, Hope, Charity, and Lucien, 1971-79, in an area of residential development and highway construction at Maitland, Florida
Edward R. German
1983, Water-Resources Investigations Report 82-51
As part of an ongoing study of lakes in central Florida, Lakes Faith, Hope, and Charity were sampled from April 1971 to June 1979 to monitor water quality before, during, and after construction of Maitland Boulevard and the Interstate Highway 4 interchange. Sampling of Lake Lucien was added to the...
