| 摘 要： | 本文以铀矿区广泛发育的黄铁矿为研究对象，通过成因矿物学方法探讨金鸡岭岩体外带铀矿床的成矿机理；论证了矿质来源于岩体的围岩，与花岗岩关系不密切；岩体侵位所引起的围岩热变质作用，以及由此而产生的变质热液，是导致成矿物质重新活化、迁移和富集成矿的根本原因。

| Abstract: | Taking pyrite as an objective for study which is widely developed in the uranium ore district, this paper discusses the metallogenetic mechanism of the uranium deposit at the exocontact zone of Jinjiling massif by means of genetic mineralogy. It has proved that ore mattersare derived from the wall rock,rather than granite. The thermal tnetamorphism in the wallrock due to massif emplacement and the metamorphic hydrothermal solutions generatedtherefrom are the cardinal reason for the remobilization,migration and concentration of orefroming matters as well as ore formation. |
