胶东地区绿岩型金矿地球化学成矿规律及其远景预测

GEOCHEMICAL MINERALIZATION OF GREENSTONE TYPE GOLD DEPOSITS IN JIAODONG AREA AND ITS PROSPECTIVE PREDICTION

通过对胶东地区绿岩中韧性剪切带的地质、地球化学特征的研究，认为胶东地区变质作用、韧性剪切作用、混合岩化作用以及新华夏系构造作用和岩浆作用等在金矿的成矿作用上具有继承关系；绿岩型金矿的成矿作用和控矿规律具有特殊性，从而突破了胶东地区新华夏构造单一控矿的认识。在此基础上。

The cognition that the gold deposits around Jiaodong area are controlled only by Cathaysian or neo Cathaysian structural system is broken through in this paper. From studying the geological and geochemical characteristics of the ductile shear zones in Jiaodong greenstone and the ore controlling law for the greenstone type gold deposits in Jiaodong area, the authors think that gold mineralization or formation is related not only to the Cathaysian or neo Cathaysian tectonics but to region metamorphism, ductile shearing, migmatization and magmatism as well. On the basis of above study, the regions for prospecting the greenstone type gold deposits are predicted.
