Significance of tourmaline-rich rocks in the Grenville Complex of St. Lawrence County, New York
C. Ervin Brown, Robert A. Ayuso
1985, Bulletin 1626-C
Feldspathic quartzite and metapelite of Middle Proterozic age north of Gouverneur, N.Y., contain abundant dravite-uvite (magnesian tourmaline). These rocks, more than 1,000 feet thick, are regionally metamorphosed to the upper amphibolite facies, are pyritic, and locally contain porphyroblastic scapolite. The rocks are underlain by talctremolite schist and a thick sequence...
Measurement of ground water velocity using Rhodamine WT dye near Sheffield, Illinois
George Garklavs, L.G. Toler
1985, Open-File Report 84-856
Ground-water flow velocity was estimated in a tract of land adjacent to a low-level radioactive-waste disposal site near Sheffield, Illinois, by measuring the time-of-travel between two wells spaced 110 feet apart. Rhodamine WT dye was the principal tracer used in the test. The leading edge and peak concentrations of Rhodamine...
Selected climatological and hydrologic data, Raton basin, Huerfano and Las Animas Counties, Colorado, and Colfax County, New Mexico
Arthur L. Geldon, P.O. Abbott
1985, Open-File Report 84-138
The hydrology of the coal-bearing Raton Basin of Colorado and New Mexico was investigated by the U.S. Geological Survey. Data in the report were collected from 1977 to 1982, mainly in the watersheds of the Apishapa and Purgatoire Rivers; data from the Cucharas, Canadian, and Vermejo River watersheds are also...
Maps showing selected geology and phosphate resources of the Johnson Creek quadrangle, Caribou County, Idaho
Pamela Palmer, Warren Barrash, P. D. Derkey, Nancy J. Wotruba, Mahasti Fakourbayat, S. T. Miller
1985, Mineral Investigations Resource Map 80
This report summarizes information on the thickness, grade, lateral continuity, phosphate resources, and ownership of phosphate-bearing units in the Meade Peak Phosphatic Shale Member of the Phosphoria Formation in the Johnson Creek quadrangle. This report is one of a series of quadrangle reports prepared by the Idaho Bureau of Mines...
Mineral potential of felsic plutonic rocks in the north-central Arabian Shield, Kingdom of Saudi Arabia
W. J. Moore
1985, Open-File Report 85-6
Fourteen plutons of Late Proterozoie age potentially favorable for rare-element mineralization have been identified in a geochemical and petrographic assessment of felsic plutonic rocks in the north-central Arabian Shield (lat 23°00'-25°00' N., long 40°00'-45°00' E.). The plutons are highly fractionated, leucocratic granitoids assigned to a major magmatic pulse that spanned...
