| 中文摘要: |
| 渣滓溪大型脉状锑矿中异体共生有白钨矿化,受同一层位(岩性)、不同构造期次(类型)控制。矿区位于2条NE向区域性逆冲断层所挟持的抬升断块内,岀露地层为新元古界板溪群五强溪组浅变质的碎屑-火山碎屑沉积岩;已发现含钨矿化(体)层28层,层控(岩控)特征明显;白钨矿化主要呈细脉状产于岩石节理裂隙中。锑矿化富集段亦为钨矿脉富集段,钨与锑为同源不同期的产物。构造应力是完成元素活化、迁移和沉淀富集的主要成矿机制,矿床属于动力变质热液成因。区内含钨(体)层众多,成矿空间较大,具有侧伏延深、分段富集的特点,其找矿前景较好。 |
| 英文摘要: |
| Scheelite mineralization is the heteromorphic paragenetic body in Zhazixi large vein-like stibnite deposit. They are controlled by the same horizon (lithology) but different tectonic stage (type). The deposit is located in the uplifted block held by 2 reverse thrusts with outcrop of low grade metamorphic clastic-volcanic debris sedimentary rock of Wuqiangxi Formation of Neoproterozoic Banxi Group. 28 scheelite mineralized layers have been found obviously lithologic control. The scheelite occurs as veinlets in joints. Scheelite and stibnite are enriched in the same place. They are of the same source but different stages. Tectonic stress is the key mechanism for activation and mobilization of Sb and W. The deposit is a dynamic metamorphic hydrothermal one. The scheelite is characterized by occurrence in multi-layers and large space and the scheelite layer characterized by extension along pitch and enrichment in multi-domains thus potential for further prospecting. |
