- Engineering Geology Applied to the Design and Operation of Underground Coal Mines
- 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.
- Lateral Ramps in the Folded Appalachians and in Overthrust Belts Worldwide—A Fundamental Element of Thrust-Belt Architecture
- 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.
- The Chemical Analysis of Argonne Premium Coal Samples
- A report about methods used to determine concentrations of 67 elements in 8 argonne premium coal samples.
- The Late Triassic Bivalve Monotis in Accreted Terranes of 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.
- Fluid Inclusions and Biomarkers in the Upper Mississippi Valley Zinc-Lead District: Implications for the Fluid-Flow and Thermal History of the Illinois Basin
- A report about the fluid inclusions in the upper Mississippi valley zinc-lead district. It discusses the consequences of fluid flow.
- The Distribution of Rare-Earth Elements in Minerals of the Monazite Family
- A report about rare-earth metals located inside minerals of the monazite family.
- Feasibility Study of Material-Balance Assessment of Petroleum from the New Albany Shale in the Illinois Basin
- A report about which intends to determine the feasibility of conducting a material-balance assessment of petroleum within a sedimentary basin.
- Geologic, Geochemical, and Isotopic Studies of a Carbonate- and Siliciclastic-Hosted Pb-Zn Deposit at Lion Hill, Vermont
- 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.
- Lead Isotopes from the Upper Mississippi Valley District: A Regional Perspective
- 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.
- Paleocene Vertebrates from Jabal Umm Himar, Kingdom of Saudi Arabia
- A report which records the Paleocene vertebrates, stratigraphy, and environment of deposition in the Jabal Umm Himar area.
- Thermodynamic Properties of Minerals and Related Substances at 298.15 K and 1 Bar (105 Pascals) Pressure and at Higher Temperatures
- 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.
- Geochemistry, Mineralogy, and Geochronology of the U.S. Virgin Islands
- 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.
- Late Cenozoic Benthic Foraminifers of the HLA Borehole Series, Beaufort Sea Shelf, Alaska
- A report about benthic foraminiferal faunas in 18 borholes from the eastern Beaufort Sea shelf.
- Petrologic Characterization of Pelitic Schists in the Western Metamorphic Belt, Coast Plutonic-Metamorphic Complex, Near Juneau, Southeastern Alaska
- A report about metamorphic rocks exposed near Juneau, Alaska. The belt they are in had a complex history of deformation, metamorphism, and plutonism.
- Quaternary Stratigraphy and Paleoceanography of the Canada Basin, Western Arctic Ocean
- 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.
- 40Ar/39Ar Age Spectra and Total-Fusion Ages of Tektites from Cretaceous-Tertiary Boundary Sedimentary Rocks in the Beloc Formation, Haiti
- A report about Haitian tektites at the paleontological K-T boundary along with an Ir abundance anomaly and shocked quartz.
