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
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 on the accompanying histograms.

Map showing anomalous copper distribution in stream sediment concentrates, Hillsboro and San Lorenzo quadrangles, exclusive of the Black Primitive Area, Sierra and Grant Counties, New Mexico
This map shows the distribution of anomalous copper 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. Distributions of copper values in each fraction are shown on the accompanying histograms.

Map showing anomalous lead distribution in stream sediment concentrates, Hillsboro and San Lorenzo quadrangles, exclusive of the Black Range Primitive Area, Sierra and Grant counties, New Mexico
This map shows the distribution of anomalous lead in the two sample fractions, magnetic (M-1) and nonmagnetic (NM-1) plotted on a base which includes sample localities, topography, and generalized geology modified from Hedlund (1975a, b). It is part of a series of maps for several metals that accompany this folio. Distributions of the lead values are shown on the accompanying histograms.
