摘要
There are three types of gold deposits in the Jiaodong gold metallogenetic domain. The strata\|bound gold deposits are a new type, which occur in a hydrocarbon\|gold double\|source bed enriched in gold (Au 174 ng/g) and organic carbon (0.007%-4.225%). At diagenetic and hydrothermal stages water and oil were simultaneously activated and the strata\|bound gold deposits were formed from interactions between water, oil and rocks. In the late Yanshanian period, gold orebodies were enriched and enlarged in response to tectonomagmatism and action of complex ore\|forming hydrothermal solutions. As a result, it is highly expected to find suparlarge gold deposits and the Yanzi area is expected to be a perspective target area.
