布敦花铜矿床位于我国重要的铜多金属成矿区带——大兴安岭铜多金属成矿区带南部。经前人研究,认为布敦花铜矿床与燕山期中酸性杂岩体具有密切的成因关系。但从1958年该矿床发现至今,对其成矿物质来源问题长期争论不休,本文从布敦花花岗闪长岩和赋矿围岩(二叠纪地层)的成矿元素丰度及布敦花铜矿床赋矿围岩、岩体和变质基底中的Pb同位素组成和矿石铅进行示踪研究,结果表明二叠系大石寨组赋矿围岩为该矿床铜成矿物质的一个重要来源。
Budunghua copper deposit is located in the important copper polymetallic metallogenic belt in China - south of Daxinganling copper-polymetallic metallogenic belt. According to previous studies, it is concluded that the Budunghuan copper deposit is closely related to the Yushanian intermediate-acidic complex. However, since the deposit was discovered in 1958 up to now, the source of mineralization has long been debated. In this paper, the metallogenic element abundances of Budunghua granite and ore-hosting rocks (Permian strata) The Pb isotopic composition and ore lead in the host rock, rock mass and metamorphic basement of the ore deposit of the copper deposit are traced. The results show that the ore-forming wall rock of the Peridian Dashizhai Formation is an important source of copper mineralization in this deposit.
