西德政府的地质人员最近在该国中部地区页岩内发现了有工业价值的铜矿脉,在其他地区还查明新的铅、锡、石墨矿床.西德政府为扭转矿产几乎完全依赖进口的局面,制定了一项投资为1680万美元的四年勘探计划,这些发现乃是该项计划实施的成果. 铜矿的发现非常鼓舞人心,因为过去西德只发现了少量与铅一锡矿床伴生的铜.西德地质人员在黑森州的黑森凹陷的罗肖森地区附近打了总计为2万英尺的10个钻孔,于980英尺深处探明了一页岩铜矿床.矿层厚度为40英寸,铜含量为2.1%.加上近地表含页岩较少的层位,总厚度可
Geological staff from the West German government recently discovered copper pulses of industrial value in the shale in the central region of the country and also identified new lead, tin and graphite deposits in other areas. The West German government almost completely relied on imports to reverse the mineralization , A four-year exploration program with an investment of 16.8 million U.S. dollars has been drawn up and these discoveries are the result of the program’s implementation. The discovery of copper deposits is very encouraging because in the past, only a few found in the West Germany associated with Pb-Sn deposits Of copper. West German geologists hit 10 holes totaling 20,000 feet near the area of Royson in the Hessian depression of Hesse and probed a shale copper deposit at a depth of 980 feet 40 inches, copper content of 2.1%. Coupled with the lower surface layer contains less shale, the total thickness can be
