Geochemical survey maps of the wildernesses and roadless areas in the White Mountains National Forest, Coos, Grafton, and Carroll counties, New Hampshire

The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine what mineral values, if any, may be present. Results must be made available to the public and be submitted to the President and the Congress. This report presents the results a geochemical survey of the Great Gulf and Presidential Range-Dry River Wilderness Areas; the Dartmouth Range, Wild River, Pemigewasset, Kinsman Mountain, Mount Wolf-Gordon Pond, Jobildunk, Carr Mountain, Sandwich Range, and the Dry River Extention (2 parcels) Roadless Areas; and the intervening and immediately surrounding areas in the White Mountain National Forest, Coos, Grafton, and Carroll Counties, New Hampshire. The Great Gulf Wilderness was established when the Wilderness Act was passed in 1964, and the Presidential Range-Dray Wiver Wilderness was established by Public Law 93-622, January 3, 1975. The Dartmouth Range, Wild River, Pemigewasset, Kinsman Mountain, Mount Wolf-Gordon Pond, Carr Mountain, and Jobildunk areas were classified as a further planning area during the Second Roadless Area Review and Evaluation (RARE II) by the U.S. Forest Service, January 1979. The White Mountain National Forest contains two established wilderness areas and ten additional RARE II roadless areas, covering a total of about 380 square miles. The location of these areas is shown on figure 1 and further information about them is contained in table 2. In order to treat all these separate areas as a single entity, they, along with the immediately surrounding areas, were combined into one study area, hereafter referred to as the study area, of about 1,300 square miles. This map is based on joint investigations by the U.S. Geological Survey and the Office of the State Geologists of New Hampshire. The geochemical survey was conducted in the summer of 1980 and was integrated with an on-going multidisciplinary study of mineral resources of the Sherbrooke and Lewiston 1°x2° quadrangles under the Conterminous United States Mineral Assessment Program (CUSMAP).

Remote detection of geochemical soil anomalies

This paper describes a preliminary experiment that was made to compare the spectral reflectance from trees growing in soil over a mineral deposit with reflectance from trees of the same species growing in a nearby unmineralized area. Although the measurements were made on a relatively small number of trees, some significant differences were obtained and the over-all results are encouraging enough to warrant additional studies. Preliminary results suggest that measurement of spectral reflectance may become a dramatic new way of detecting geochemical soil anomalies by remote means in tree-covered areas.

Plastic standards for geochemical prospecting

Plastic standards for use in geochemical prospecting have been prepared by impregnating a clear thermosetting resin with different amounts of a stable dye or colored metal complex. The colored plastic is molded or subsequently milled into convenient shapes to form standards that are less bulky and more stable than the liquid standards conventionally used in rapid field methods. The use of such standards is limited only by the availability of stable coloring materials. The preparation of plastic standards for use with copper, zinc, tin, and mercury field procedures is described.

A preliminary report of geochemical investigations in the Blackbird District

This paper reviews an experimental geochemical prospecting survey in the Blackbird cobalt-copper mining district. The district is in east-central Idaho, about 20 miles west-southwest of Salmon. The area is one of deeply weathered nearly flat-topped upland surfaces cut by steep-walled valleys which are tributary to the canyon of Panther Creek. Most of the area has a relatively heavy vegetative cover, and outcrops are scarce except on the sides of the steeper valleys* Because of the importance of the surficial deposits and soils and the physiographic history of the region on the interpretation of the geochemical data, a separate chapter on this subject by Gerald H. Richmond follows the following brief description of the geology of the district.
