前言探寻金属硫化矿通常是采用地质填图方法,圈出岩石露头和残积物,再用某种物探方法圈出未风化的岩石的物性变化范围,或是用化探采样圈出金属元素的分散晕.现有地面物探方法中,确定布钻位置通常还采用激发极化法.磁法、重力法和电磁法对于矿体的存在,有可能提供更确凿的资料.自然电场法以前曾广泛地用过,但现在许多地质和物探人员都认为它不太合用.普遍地认为自电法的效果不明显.自电法没有获得异常,并不能排除有矿体存在的可能性.在整个澳大利亚广泛地分布着导电
Preface Exploration of metal sulphide ore is usually carried out by geologic mapping method, circling outcrops and residuals, and then using a geophysical method to circle the range of physical properties of non-weathered rocks, or to scatter the metal elements by geochemical sampling Halo. Existing ground geophysical methods to determine the location of cloth drilling is usually used to stimulate polarization method.Magnetic, gravimetric and electromagnetic method for the presence of orebodies may provide more conclusive information.Natural electric field method has been widely Used, but now many geologists and geophysical personnel think it is not suitable for use .It is generally believed that the effect of self-electric method is not obvious.Automatic method without exception, and can not rule out the possibility of ore body exists in Australia Distributed with conductive
