相山矿田铀与多金属矿化H-O-S-Pb同位素组成及对比研究
H-O-S-Pb isotope composition and comparison of uranium and polymetallic mineralization in the Xiangshan orefield
摘要
Abstract
Xiangshan ore field is the largest volcanic-hosted uranium ore field in China.Continuous discoveries of lead,zinc,silver,and copper polymetallic mineralization at depth beneath uranium mineralization reveal a spatial distribution pattern of"upper uranium-lower polymetallic"mineralization.Therefore,the genetic relationship between polymetallic mineralization and large-scale uranium mineralization has become another research focus in the Xiangshan ore field.This study systematically investigated the H-O-S-Pb isotopic compositions and conducted comprehensive comparative analyses of uranium and polymetallic mineralization.Results indicate that uranium mineralization involved more atmospheric precipitation and crustal-derived materials compared to polymetallic mineralization.The sulfur isotopic composition of polymetallic mineralization in the Xiangshan area shows distinct differences from typical regional polymetallic deposits.At least one stage of relatively uranium-enriched mineralization process has been identified during the polymetallic mineralization in Xiangshan region.关键词
