INDUCED POLARIZATION SURVEY OF SULFIDE-BEARING ROCKS IN EASTERN TENNESSEE AND WESTERN NORTH CAROLINA

Iron pyrite in minute crystal form occurs extensively in the Anakeesta Shale formations in the Appalachian Mountains and can cause serious environmental problems when exposed in highway cuts and embankments. Many remote sensing techniques were evaluated in an effort to find a means of economically, accurately, and expeditiously locating these low-grade sulfide mineral deposits and to establish their vertical and longitudinal boundaries along a proposed highway corridor. Other benefits also are discussed. Good results were achieved by using induced polarization techniques along a route in the Tellico Mountains of eastern Tennessee and western North Carolina. (Author)
