Water levels and artesian pressures in the Chad Basin of northeastern Nigeria, 1963-68
S.W. Carmalt, G. Chase Tibbitts Jr.
1969, Open-File Report 72-61
This report presents records of water levels and artesian pressures collected during 1963-68 on an observational network of 116 dug wells and boreholes (drilled wells) in the Chad Basin of northeastern Nigeria. The Chad Basin is underlain by the Chad Formation, a series of fluvio-lacustrine sediments which attain a thickness...
Summary of geologic effects of the Boxcar event, Nevada Test Site
Dayton Delbert Dickey, F. A. McKeown, William L. Ellis
1969, Open-File Report 69-74
A high-yield underground nuclear explosion at the U20i site, formed a sink 1,000 feet in diameter above the explosion point. Fractures opened as far as 20,000 feet from the explosion and rock-falls occurred as far as 15 miles. Most fractures were coincidental with north-trending naturally occurring faults. Maximum displacement along...
Preliminary carbonate lithofacies maps and possible dolomite porosity trends, Mississippian-Pennsylvanian Lisburne Group, North Slope, Alaska
Augustus K. Armstrong
1969, Open-File Report 69-13
Carbonate porosity within the Mississippian-Pennsylvanian age Lisburne Group is probably extensively developed in the subsurface of the North Slope. The Lisburne Group may prove to be one of the more significant reservoir zones in the region and should not be overlooked in any exploration program. Isopach maps for the total...
