摘要
The Dayingezhuang gold deposit occurs in the Zhaoping fault which lies in the contact zone between the Linglong granite and metamorphic rocks of the 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.
