| 摘 要： | Geochemical characteristics of the Upper Archean-Lower Proterozoic Jiaodong Group-the host rocks of the famous Jiaodong gold deposit are described in this paper.It is shown that the Jiaodong Group is an important Au-bearing formation containing 19.5 ppb Au on average, about 5 times as much the abun-dance in the crust.It is also found that the distribution of gold in the strata is uneven and that plagioclase amphibolite is the prospective Au -bearing rock.In the processes of regional metamorphism, migmatization and fault -remelting ,gold in the source bed was remobilized and concentrated to from various types ofgold deposits in this province.

| Abstract: | Geochemical characteristics of the Upper Archean-Lower Proterozoic Jiaodong Group — the host rocks of the famous Jiaodong
gold deposit are described in this paper. It is shown that the Jiaodong Group is an important Au-bearing formation containing
19.5 ppb Au on average, about 5 times as much the abundance in the crust. It is also found that the distribution of gold in
the strata is uneven and that plagioclase amphibolite is the prospective Au-bearing rock. In the processes of regional metamorphism,
migmatization and fault-remelting, gold in the source bed was remobilized and concentrated to form various types of gold deposits
in this province. |
