江西永平十字头钼矿的大地构造位置位于钦杭成矿带中段南部,扬子板块与华夏板块的拼接地带,萍乡-广丰深断裂南侧的晚古生代裂陷槽内(抚州-饶南坳陷)。十字头钼矿为刚发现的矿床,研究工作还不深入。基于此,作者试图通过S、Pb同位素来探讨矿床的成矿物质来源。S同位素:由十字头钼矿床石英-硫化物脉中金属硫化物的S同位素组成可知,本区金属硫化物的 The geotectonic location of the Phongmutou molybdenum deposit in Jiangxi Province is located in the southern part of the mid-Qinling-Chenggou metallogenic belt, the splicing zone between the Yangtze plate and the Huaxia plate, the Late Paleozoic rift groove to the south of Pingxiang-Guangfeng deep fault (Fuzhou-Raoan depression trap). Cross head molybdenum mine just discovered deposits, research work is not yet in-depth. Based on this, the author attempts to explore the ore-forming material sources of the deposit by means of S and Pb isotopes. S isotopes: S isotopic compositions of the metal sulfides in the quartz-sulfide vein of the Phillipsian molybdenum deposit suggest that the
