摘要
江西石坞金矿床位于江西省金山金矿田金山金矿西部,是一个受韧性剪切带控制的变质热液型大型岩金矿床。矿化带叠加在构造岩分带与蚀变分带之中,呈“三体一位”产出,矿体形态较简单,厚度较不稳定,品位与厚度分布成正比,成矿物质来源为同源型,成矿作用是“火山沉积─区域变质─韧性剪切带控矿容矿─改造叠加”。文章通过对该矿成矿特征及矿床成因分析,提出了找矿方向。
Metamorphic hydrothermal Shiwu gold deposit was located in the western part of Jinshan gold ore field of Jiangxi Province, and controlled by a ductile shear zone. Metallogenic belts are super - posited on tectonite and alteration rocks. Ore shapes are simple with variable thickness. Ore grade has direct ratio with thickness. Gold mineralization is “volcanic sedimentation-regional metamorphism-ore hosting shear zone-reformation and super-position”. Based on analyses of metallogenic characteristic and ore genesis, future ore prospecting is proposed.
