A report which discusses in detail how the disciplines of geology and geotechnology, also known as engineering geology, apply to exploration, design, and operation of underground coal mines.
A report about the geochemical and mineralogic study of the U.S. Virgin Islands indicates the presence of a previously undocumented Sn-Pb and precious metals.
A report about the potential for Irish-type Pb-Zn deposits in a platform rocks of western Vermont; however, at Lion Hill they contain enrichments of Pb, Zn, and Cu rather than a Pb, Zn, and Ag association.
A collection of papers which report on the geologic investigations in Alaska. It represents the broad range of U.S. Geologic Survey research activities carried out in Alaska.
A report about late triassic bivalves of the genus monotis. So far, 14 kinds of Monotis that differ in species or subspecies level can be recognized from Alaska.
A report about lateral ramps which are zones where décollements change stratigraphic level along a strike. This report suggests that many cross-strike features may be underlain by lateral ramps that serve to transfer décollements from one stratigraphic level to another in the same manner as frontal ramp, but in a direction normal to the strike of the fold belt.
A report about new lead isotopic data on galena from within and peripheral to the Upper Mississippi Valley which make it possible to trace a pathway traversed by the mineralizing fluids beyond the boundary of the main district.
A report which presents the results of the processing and analysis of commercial satellite image data acquired over the nuclear power plant at Chernobyl in the Soviet Ukraine.
A report about lithologic, paleontologic, and paleomagnetic analyses of sediment cores from Northwind Ridge in the western Canada Basin which provides a stratigraphic framework for interpreting the upper Quaternary paleoceanographic records of the western Arctic Ocean.
A report about sedimentary processes on the southern margin of Georges Bank which is based on observations from research submersibles of bottom features, on size analyses of sediment samples, and on measurements of current strength and flow direction.
A report about values for the entropy, molar volume, and for the enthalpy and Gibbs energy of formation for the elements and minerals and substances at 298.15 K.
