Abstract:Liaoshang gold deposit locates in the northeastern margin of Jiaolai basin. It is the first super large gold deposit discovered in eastern Jiaodong Peninsula. The gold mineralization here is characterized by filling activities, and main goldbearing minerals are idiomorphic hypidiomorphic pyrites and dolomites, which are always developed as net viens, veinlets and micro veinlets in the rock fissures, or as big veins filled in the fault structures. The ores are mainly categorized to goldbearing pyritedolomite veins and altered rocks bearing pyritedolomite veins. After comprehensive comparison and analysis, Liaoshang can be defined as a new type named pyritedolomite vein type gold deposit. The discovery endows the margin areas of the Jiaolai Basin with good prospecting potentiality.
