Restored stratigraphic cross sections and coal correlations in the Tongue River member of the Fort Union Formation, Powder River area, Montana
R. M. Flores
1979, Miscellaneous Field Studies Map 1127
Exposures of the lower two thirds of the Tongue River Member of the Paleocene Fort Union Formation were measured along the Powder River valley in southeastern Montana in the Moorhead and Birney-Broadus coalfields.  This report documents the stratigraphic variations, lateral continuity of partly eroded coal beds along the line of...
Lake Ontario geological and geophysical data sources
Deborah R. Hutchinson, Richard J. Wold
1979, Miscellaneous Field Studies Map 1103
A bibliography of various geological and geophysical data sources was compiled as part of an overall effort to evaluate the status of research on the Great Lakes.  We hope that such a summary will be a catalyst for additional work and be an aid in planning future work.  Our presentation...
Map showing high-purity silica sand of Middle Ordovician age in the Midwestern states
Keith B. Ketner
1979, Miscellaneous Field Studies Map 1097
Certain quartz sands of Middle Ordovician age in the Midwestern States are well known for their purity and are exploited for a wide variety of industrial uses. The principal Middle Ordovician formations containing high-purity sands are the St. Peter Sandstone which crops out extensively from Minnesota to Arkansas; the Everton...
Geochemical and generalized geologic map showing distribution and abundance of antimony and niobium in stream sediments, Chandalar 1° by 3° quadrangle, Alaska
S.P. Marsh, D.E. Detra, S.C. Smith
1979, Miscellaneous Field Studies Map 878-H
This geochemical map shows the distribution and abundance of antimony (Sb) and niobium (Nb) in -80 mesh (177 micrometers) stream sediment samples in the Chandalar quadrangle, Alaska. The map is one of a series of geochemical maps that together with the background information circular (Reiser and others, 1978) comprise the folio...

S.P. Marsh, D.E. Detra, S.C. Smith
1979, Miscellaneous Field Studies Map 878-F
This geochemical map shows the distribution and abundance of nickel (Ni), cobalt (Co), lanthanum (La), and yttrium (Y) in -80 mesh (177 micrometers) stream sediment samples in the Chandalar quadrangle, Alaska. The map is a part of a series of geochemical maps that together with the background information circular (Reiser...
