The results have demonstrated that the studying area underwent four stages of geotectonie evolution,namely, pre-geosyneline, geosyneline, platform and diwa stages. The gold deposits were formed during diwa stage of the iste Yanshanian Age, undergoing multi-tectono-magmatic activities. Jiaodong Group of the Upper Archean Erathem was the source bed of gold deposits. Granitie msamatic aetivities dived the ore-forming elements transporting. Tectonic activities controlled the formation, the distribution of gold deposits and the scale and the shape of ore body, ete.. The gold deposits exhibit the eharacteristics multi-source of ore-forming elemcnts, multi-genesis, multi-ote-conttolling foctors, multi-genstical types and multi-stage mineralization. They belong to mantle-erust deposits.
