REE Geochemical Characteristics of Hetaoping Pb-Zn Deposit,Baoshan County,Western Yunnan Province and Its Genetic Implications
摘要
Abstract
The Hetaoping Pb-Zn deposit of Baoshan County is located in western Yunnan Province.It is one of large-scale lead-zinc(copper-silver)polymetallic deposits characterized of vein skarn-type ore-bearing deposits and controlled by fractures in Three River area of Yunnan Province,southwestern China.The authors systemati-cally studied rare earth element (REE )geochemical characteristics of the surrounding rocks,Pb-Zn ores and hydrothermal veins of Hetaoping Pb-Zn ore fields.The results show that REE in the surrounding rocks is mainly enriched in clay minerals.The skarn fluids extract the REE in the surrounding rocks and change their REE chondrite-normalized patterns.For now,exploration revealed shallow skarn diagenetic fluid is in medium-low temperature and acid-weak acid fluid,with the fluid evolutionary,the acidity of the fluid increases.Combined with the previous researching results,it is considered that the Hetaoping Pb-Zn deposit is a distal skarn-type Pb-Zn deposit and the rock-and ore-formations of the skarm and lead-zine (copper-silver)controlled by magmatic hydrothermal.关键词
