摘要
根据山东招掖地区不同地质体的金丰度和O,S,H,Pb,Rb,Sr的同位素以及稀土元素的地球化学研究成果,探讨了招掖金矿带的成矿物质来源,并提出了新的找矿方向。作者认为:太古界胶东群是形成金矿床的初始矿源层,金的成矿作用发生于中生代地洼阶段,今后应注意在郭家岭型岩体中及其与玲珑型岩体的接触部位找矿。
According to the calculation of the contents of released gold and the applications of mathematical methods and the geochemical studies on theabundance of gold, the O, S, H, Pb, Rb and Sr isotopes and REE indifferent kinds of geological bodies in Zhao-Ye gold belt, the source of ore-forming materials in the belt is discussed. The results show that the ore-forming materials are products of inherited evolution. A new direction ofgold prospecting in this belt is proposed.
