Hydrogeochemistry and simulated solute transport, Piceance Basin, northwestern Colorado
S. G. Robson, G.J. Saulnier Jr.
1981, Professional Paper 1196
Oil-shale mining activities in Piceance basin in northwestern Colorado could adversely affect the ground- and surface-water quality in the basin. This study of the hydrology and geochemistry of the area used ground-water solute-transport-modeling techniques to investigate the possible impact of the mines on water quality. Maps of the extent and...
Echinoderms from Middle and Upper Ordovician rocks of Kentucky

Geochemical variability of natural soils and reclaimed mine-spoil soils in the San Juan Basin, New Mexico
L. P. Gough, R. C. Severson
1981, Professional Paper 1134-C
An inventory of total-and extractable-element concentrations in soils was made for three areas of the San Juan Basin in New Mexico: (1) the broad area likely to be affected by energy-related development. (2) an area of soils considered to have potential for use as topsoil in mined-land reclamation. and (3)...
Biogeochemical variability of plants at native and altered sites, San Juan Basin, New Mexico
L. P. Gough, R. C. Severson
1981, Professional Paper 1134-D
The San Juan Basin is becoming a major energy resource region. The anticipated increase in strip mining for coal can be expected to alter the geochemical and biogeochemical environment. because such activities destroy the native vegetation communities, rearrange the rock strata, and disrupt natural soil development. This study investigated the...

An annotated bibliography of literature on Alaska water birds
Colleen M. Handel, Margaret R. Petersen, Robert E. Gill Jr., Calvin J. Lensink
1981, FWS/OBS 81/12
The demand for information on birds in Alaska has surged within the past few years, primarily because of the need to adequately assess the impacts of a wide range of planned developments. The accompanying increase in studies of avian populations has resulted in a growing need for a comprehensive bibliography...

Mathematical model of gamma-ray spectrometry borehole logging for quantitative analysis
Ulrich Schimschal
1981, Open-File Report 81-402
A technique for analyzing gamma-ray spectral-logging data has been developed, in which a digital computer is used to calculate the effects of gamma-ray attentuation in a borehole environment. The computer model allows for the calculation of the effects of lithology, porosity, density, and the thickness of a horizontal layer of...
