Preliminary Investigation of Limestone, Quartzite, and Dolomite Resources Near the Proposed Rampart Dam in Central Alaska.

• Description:
  Spot sampling of rock exposures, geologic reconnaissance, and preliminary laboratory tests show possible sources of limestone, silica, and dolomite 15 miles southwest of the proposed rampart damsite in central Alaska. These raw material sources are outside the reservoir area and could be made readily accessible to the damsite either by highway or railroad. Sample analyses indicate some limestone pure enough to be used in calcium carbide production and excellent for use as the major ingredient in the production of cement. The discovery of high purity silica in low iron quartzites indicates a possible source of a material having many electrometallurgical, glass, and abrasive uses. Dolomites of a grade used in the ferrosilicon process of magnesium production were indicated by float and grab sampling. [Description provided by NIOSH]
