The u.S Bureau of Mines conducted five reconnaissance magnetometer traverses across a small abandoned chromite mine in the State Line District of Pennsylvania and Maryland to determine the geophysical response of the area. The results indicate that more extensive geophysical surveys of the region might establish some worthwhile guidelines for chromite exploration. While chromite only rarely can be detected directly by magnetic methods, there is a possibility that geophysical signatures in the adjacent host rock could provide some guidelines for further exploration. Prior to 1875, all the chromite produced in the United States came from the State Line District, and the potential for discovering additional podiform deposits could be significant. Virtually no state-of-the-art geophysical or geochemical studies have been conducted in this district since World War II, and sizable areas remain undeveloped and suitable for exploration. While the results reported in this paper are not supported by drilling, they may encourage others to investigate the area more fully for improved methods of detecting subsurface podiform chromite deposits. New theories on the emplacement of ophiolites also could contribute to an assessment of the chromite potential of the serpentinite belt.
