Abnormal copper, lead, and zinc content of soil near metalliferous veins

Controls of the spatial variability of Cr concentration in topsoils of a central French landscape

“…Such homogenisation may be explained in various ways: - Huff (1952) and Barbier and Wilhelm (1978) showed that natural erosion, such as creep and solifluction, causes mechanical dispersion of soil and homogenisation of soil chemical properties in surface horizons. Soil cultivation also plays a major role.…”

Principles of geochemical prospecting

“…Geochemical anomalies in residual cover may be distorted by downslope movement of the soil. The result is an asymmetrical curve in which the metal content fails off less rapidly OH the downhill side than in the Uphill side, as illustrated in the diagrams presented by Huff (1952). Asymmetry of this kind can also be caused by the action of metal-rich solutions depositing metal in the soil on the downslope side, although the net effect is the same whatever the cause.…”

“…Details of some of these surveys have been published. See items numbered 4, 5, 22, 23, 26, 27, 36, 59, 66, 85, 94, 103, 104, 108, 110, and 117 abstracted by Harbaugh (1953) and also the following: Fersman, 1939;Gilbert, 1951Gilbert, , 1953Hawkes, 1954;Huff, 1952;Kennedy, 1952;Nackowski, 1952;Pierce and Dias,. 1950;and Shima, 1953e, 195314 Much of the work, however, has been sponsored by private mining companies as part of their exploration program, where commercial considerations prevent the release of information to the public.…”

Lead in the environment

“…In the lead mining district of southwestern Wisconsin, residual concentrations of weathered galena fragments were found over some of the lead veins (Huff, 1952). These residual concentrations were left by the decomposition and mechanical washing away of the lighter minerals.…”

“…The dispersion of lead in residual soil is demonstrated effectively by study of soil samples collected near lead-rich veins (Huff, 1952). Soil samples collected across a lead-zinc vein in Wisconsin (fig.…”
