| 摘 要： | 邹—石断裂分布在江西相山铀矿田西部,前人认为是一条重要的成矿构造.本次研究发现矿体并不产于邹—石断裂本身,断裂没有控制矿体几何形态,不是矿质直接充填或交代的地质构造单元,不具成矿构造的特点.由于邹石断裂在地形上呈现线性沟谷,遥感影像图上呈现清晰的线性影像,切错了花岗斑岩.构造岩主要是围岩的破碎角砾、构造透镜体和断层泥,以脆性变形为主,温热水与之关系密切,故认为,邹—石断裂具有新构造活动的踪迹,可能形成于新近纪—第四纪,属矿后构造.

| Abstract: | Located in the western part of Xiangshan uranium ore field in Jiangxi Province, Zoushi fault is generally considered as an important ore-forming structure. Thepresenl study clarifies that the uranium ore bodies are not occurred within the Zoushi fault and the geometric forms of ore-bodies are not controlled by Zoushi fauh. The Zoushi fault is not a geological structure directly filled or alternated by ore forming materials, and has no characteristics of ore-forming structure. As theZoushi fault shows a linear valley re lief and clear linear remote sensing image, cutting across the granite porphyries, the tectonites include rebble breccia, tectonic len,tectonic clay, showing characteristics of brittle deformation and close relationship with hot water. The author believes that the Zoushi fault is a postmineral structure with the traces of the new tectonic activities and is possible formed in the Neogene - Quaternary. |
