Map showing anomalous silver distribution in stream sediment concentrates, Hillsboro and San Lorenzo quadrangles, exclusive of the Black Range Primitive Area, Sierra and Grant Counties, New Mexico
H. V. Alminas, K. C. Watts, D. F. Siems, V. E. Kraxberger
1978, Miscellaneous Field Studies Map 900-C
This map shows the distribution of anomalous silver in the nonmagnetic (NM-1) sample fraction plotted on a base which includes sample localities, topography, and generalized geology from Hedlund (1975a, b). It is part of a series of maps for several metals that accompany this folio. Distributions of silver values are shown...
Map showing anomalous molybdenum distribution in stream sediment concentrates, Hillsboro and San Lorenzo quadrangles, exclusive of the Black Range Primitive Area, Sierra and Grant counties, New Mexico
H. V. Alminas, K.C. Watts, D. F. Siems, V. E. Kraxberger
1978, Miscellaneous Field Studies Map 900-E
This map shows the distribution of anomalous molybdenum in the two sample fractions magnetic (M-1) and nonmagnetic (NM-1) plotted on a base which includes sample localities, topography, and generalized geology from Hedlund (1975a, b). It is part of a series of maps for several metals that accompany this folio. Distribution...
Geochemical map showing the distribution and abundance of copper in stream sediments in the Seward and Blying Sound quadrangles, Alaska
R. B. Tripp, W.D. Crim, E.F. Cooley, G.W. Day
1978, Miscellaneous Field Studies Map 880-E
Reconnaissance geochemical and mineralogical sampling was done in the Seward and Blying Sound quadrangles during 1975 and 1976 as part of the Alaska Mineral Resources Assessment Program (AMRAP). This map shows the distribution and abundance of copper in stream-sediment samples. Stream-sediment samples were collected at 569 sites from active stream channels...
Map showing thickness of young bay mud, southern San Francisco Bay, California
Sandra D. McDonald, Donald R. Nichols, Nancy A. Wright, Brian Atwater
1978, Miscellaneous Field Studies Map 976
Soft water-saturated estuarine deposits less than 10,000 years old underlie the southern part of San Francisco bay and the present and former marshlands that border the bay. Known locally as bay mud or as young bay mud, these deposits, and the estuarine environment that produces them, are of major importance...
