玲珑花岗岩在大尹格庄金矿成矿系统中的作用
Significance of the Linglong Granite in the Metallogenic System of theDayingezhuang Gold Deposit in Eastern Shandong Province
摘要
Abstract
The Dayingezhuang gold deposit occurs in the Zlaoping fault which lies in the contact zone between the Linglong granite and metamorphic rocks ofthe Jiaodong Group. The Linglong granite is rich in Si, Al, Ba, Na, and Ba, poor in Mg, Y, Yb, Ti and HREE, and has positive Eu anomalies and a high Mg index. It is similar to the C-type adakite. This deposit is the result of repeated melting of the granite. The Linglong granite is the product of basal greenstone melting equivalent to the mine embryos of the gold deposits in Eastern Shandong Province. With crustal thinning and tension, the substantial heat made the Lingong granite remelt and mixed with upper mantle material, forming a thermal convection system. A huge amount of gold was migrated and precipitated in the faults and fractures which were formed during multi-period tectonic movements. This system indicates that there is a large prospecting potential of ore-searching at the depth of the Zhanping fault.关键词
