摘要 60矿床位于赣杭带中段盛源火山盆地北东边缘,是一个以铀为主、伴生磷的大型矿床,矿化赋存于EW向断裂带中的上侏罗统鹅湖岭组中下部火山岩系地层中,矿体呈似层状、透镜状,层控明显,矿石的结构构造与围岩相似,火山气液参与了成矿作用,矿床属火山喷气—沉积矿床。 The 60 deposit is located on the northeast margin of the Shengyuan volcanic basin in the middle sector of the Ganhang Belt. It is a large deposit producing mainly uranium with phosphorus as by-product. The mineralization occurs in the volcanic rock strata in the middle-lower part of the Upper Jurassic Ehuling Formation within the E-W fault zone. Occurring in bedded and lens form, the orebodies are obviously stratabound. The texture and structure of the ore are similar to those of the wall rock. Gas and liquid of volcanic origin have taken part in mineralization, and the deposit is of a volcanic exhalative-sedimentary type.
