江西相山矿田鹏姑山地区铀成矿条件及资源潜力分析

鹏姑山地区位于相山矿田西部的居隆庵菱形断块与芙竹坪菱形断块所夹持的"锐角"部位,东邻邹家山、船坑及平顶山矿床,西靠书塘、李家岭及居隆庵矿床,是书塘的北东段与邹家山4号带西南延伸段。区内断裂构造发育,主要有贯穿整个鹏姑山地区的北东向邹家山-石洞和北西向济河口两个主断裂,其次是主断裂派生的近南北向断裂,以及包含火山塌陷构造。通过近几年的勘查工作,在区内西端初步发现一条受近南北向济河口断裂控制的铀成矿带。矿体受构造、岩性组间界面以及蚀变复合控制。现有的资料显示,该区铀成矿地质条件优越,铀资源潜力大。

Uranium mineralization conditions and resource potential in Penggushan area, Xiangshan uranium orefield, Jiangxi Province

Penggushan area is located in the cross regin between Julongan and Fuzhuping rhombic fault block in the west of Xiangshan, closing to Zoujiashan, Chuangkeng and Pingdingshan deposits in the east and Shutang, Lijialing and Julongan deposits in the west. It is also the North-east section of Shutang and the Southwest extension of Zoujiashan No.4 belt. The NE-trending Zou-Shi fault, the NW-trending Jihekou fault and the N-S-trending fault which derived from the main fault and the volcanic collapse structure is the main fault in this study area. A uranium metallogenic belt has been verified by the exploration work in the west of Pengushan area in recent years. The uranium orebody is controlled by structure, lithologic interfacial and alteration. The available data show that the uranium metallogenic geological conditions in this area are superior and the uranium resources have considerable resource potential.
