Abstract

Abstract: The trace rare earth elements of rocks and ores in Xiaotongjiapuzi gold deposit was analyzed to discuss the mineral sources and the effect of Indosinian-Yanshan magmatic activities on mineralization.Gaixian Formation schists and Dashiqiao Formation marbles exhibit similar variation trends of trace elements and rare earth distribution patterns， and Indosinian granite showed little difference in trace elements such as P， Zr and Hf， et al.Lyuliang-Yanshan period magmatic rock mass lacked Er， reflecting that gold mineralization was closely related to the strata and magmatic rocks. Characteristics of rare earth elements suggested that the ore-forming hydrothermal was a reductive fluid rich in Cl^-， and metallogenic material source and ore-forming fluid source was complex.Lyuliang period granite， Yanshan period granite， Gaixian Formation schists and Dashiqiao Formation marbles all provided ore-forming material for the formation of ore bodies， and deep metallogenic material participated in the mineralization.Xiaotongjiapuzi gold deposit is a magmatic hydrothermal superimposition type gold deposit.

Key words: Qingchengzi ore concentration area, Xiaotongjiapuzi gold deposit, trace rare earth elements, magmatic hydrothermal
