Gold Metallogenic Features and Prospecting in the Margin of the Mesozoic Basins, Jiaodong Peninsula
摘要
Abstract
Breakthrough in gold exploration is outstanding in the margin areas of the Mesozoic basins in Jiaodong Peninsula where a batch of mid-large gold deposits are successively discovered like Jinzhuang and Songjiagou in Muping, Pengjiakuang and Xilaokou in Rushan, Guocheng in Haiyang, Dazhuangzi in Pingdu, Xilin and Hushan in Qixia, and Dujiaai in Fushan. Judging from the occurrence features, this area possesses two gold metallogenic types, namely the Pengjiakuang type-(the alteration complex gold deposits in the slip-detachment belts along the basin margins) and the Songjiagou type-(the alteration conglomerate gold deposits in the fissure-abundant belts inside the basins). In accord with other areas'metallogenic age in Jiaodong, the isotopic age of the gold deposits in the basin margins drops into 128.49~115 Ma, and the metallogenic material is characterized by the mixture of crust and mantle derived substances. From the study and analysis of local metallogenic regularities, this article de-fines five significant metallogenic areas with tremendous prospecting potential.关键词
