摘　　要：Gold deposits in eastern Liaoning, northeast China are hosted in the middle and upper parts of a Paleoproterozoic volcanic-sedimentary succession, which consists of interlayered carbonates and fine-grained clastics. This paper discusses the geological features of ore-bearing formations, ore-controlling structures and metallogenetic characteristics. Analysis of ore-controlling factors suggested that the schists from the Gaixian formatyion, syngenetic faults and ductile shear zones are principal ore controls over mineralization and thereafter indicators for gold exploration.Gold deposits in eastern Liaoning, northeast China are hosted in the middle and upper parts of a Paleoproterozoic volcanic-sedimentary succession, which consists of interlayered carbonates and fine-grained clastics.
