| 摘 要： | 日龙沟锡多金属矿床位于鄂拉山多金属成矿带中的塞什塘—铜峪沟—日龙沟多金属成矿亚带西端;矿区内的下二叠统地层为矿床的主要赋矿层位,矿体的产出明显受一定的地层层位控制,虽然不连续,但总体呈层状,页层间破碎带产出;矿化类型总体属蚀变岩型,矿床成因为沉积一变质改造型。

| Abstract: | Rilonggou tin - polymetallic deposit is located at the western part of Saishitang-Tongyugou-Rilonggou submetallogenic belt of the Elashan polymetallogenic belt.The ores are marly occurred in the lower Permianin strata and their occurrences were controlled by definite strata.They occurred along bedded breccciation zones and show stratum-shape feature despite their uncontinuity. The deposit is of alterred rock type as a whole and is of sedimentation-metamorphism modification type in origin. |
