Geochemical survey of the Lusk Creek Roadless Area, Pope County, Illinois
John S. Klasner, Gordon W. Day
1984, Miscellaneous Field Studies Map 1405-B
The Lusk Creek Roadless Area (Index map) lies along the western edge of the Illinois-Kentucky fluorspar district in which flourite deposits occur as lenticular-type veins emplaced along fult zones or as tratiform-shaped bedding-replacement deposits that occur along fault zones (Grogan and Bradbury, 1967; Trace, 1974). Although mineralogy varies between deposits,...
A Galerkin finite-element flow model to predict the transient response of a radially symmetric aquifer
Thomas E. Reilly
1984, Water Supply Paper 2198
A computer program developed to evaluate radial flow of ground water, such as at a pumping well, recharge basin, or injection well, is capable of simulating anisotropic, inhomogenous, confined, or pseudo-unconfined (constant saturated thickness) conditions. Results compare well with those calculated from published analytical and model solutions. The program is...
Bathymetric map of Lydonia Canyon, U.S. Atlantic Outer Continental Shelf
Bradford Butman, John A. Moody
1984, Miscellaneous Field Studies Map 1710
Lydonia Canyon is one of several large submarine canyons that indent the eastern U.S. Continental Shelf along the southern flank of Georges Bank (Index map).  This bathymetric map of the upper part of Lydonia Canyon (water depths shallower than about 2,00 m) was prepared as part of a study of...
Wireline-rotary air coring of the Bandelier Tuff, Los Alamos, New Mexico
W.E. Teasdale, R.R. Pemberton
1984, Water-Resources Investigations Report 84-4176
This paper describes experiments using wireline-rotary air-coring techniques conducted in the Bandelier Tuff using a modified standard wireline core-barrel system. The modified equipment was used to collect uncontaminated cores of unconsolidated ash and indurated tuff at Los Alamos, New Mexico. Core recovery obtained from the 210-foot deep test hole was...
