1981, Open-File Report 81-751
Coring operations were conducted in the west basin of Clear Lake during July and August 1980 to produce a regional Quaternary reference section. A 177-m-long core (CL-80-1) was taken, which also augments and extends a previous study of eight shorter cores collected from Clear Lake in 1973. Core CL-80-1 was...

Geochemistry of water in the Fort Union formation of the northern Powder River basin, southeastern Montana
Roger W. Lee
1981, Water Supply Paper 2076
Shallow water in the coal-bearing Paleocene Fort Union Formation of southeastern Montana was investigated to provide a better understanding of its geochemistry. Springs, wells less than 200 feet deep, and wells greater than 200 feet deep were observed to have different water qualities. Overall, the ground water exists as two...
Metamorphic mineral assemblages of slightly calcic pelitic rocks in and around the Taconic Allochthon, southwestern Massachusetts and adjacent Connecticut and New York

1981, Professional Paper 1113
The mineral assemblages from metamorphosed slightly calcic pelitic rocks of the Taconic Range in southwestern Massachusetts and adjacent areas of Connecticut and New York were studied petrographically and chemically. These rocks vary in metamorphic grade from those below the chloritoid zone through the chloritoid and garnet zones into the kyanite-staurolite...
Geochemistry of spring water, southeastern Uinta Basin, Utah and Colorado

1981, Water Supply Paper 2074
The chemical quality of water in the southeastern Uinta Basin, Utah and Colorado, is important to the future development of the abundant oil-shale resources of the area. This report examines the observed changes in chemistry as water circulates in both shallow and deep ground-water systems. Mass-balance and mass- transfer calculations...
