一、河北省某地,铅锌矿是一个生在石灰岩中的中、低温热液脉状裂隙充填交代矿床,矿化面积很广。1954至1955年经过地表、坑道揭露和地质测量等工作,估算全区储量很小,认为矿床远景不大,地质工作因而停顿了两年多。1958年,在总路线的光辉照耀下,某地质队重新在此进行普查工作。同年九月间,地质部苏 First, somewhere in Hebei Province, lead-zinc mine is a medium and low-temperature hydrothermal veins-rifted fissure-bearing deposit deposited in limestone with a wide mineralization area. From 1954 to 1955 after surface, tunnel exposure and geological surveying work, it is estimated that the reserves in the whole area are small, and the prospect of the deposit is not big and the geological work has been stopped for more than two years. In 1958, under the shining rays of the general route, a geological team re-conducted census work here. In September the same year, the Department of Geology Su
