| 中文摘要: |
| 勘查实践统计,扬子地台南东缘低温热液型重晶石矿集中赋存于早奥陶世红花园组( O1h)、桐梓组( O1t)脆 性灰岩的张性裂隙中,上部被奥陶系大湾组( O1d)页岩、下部被桐梓组( O1ty)页岩封闭,具有一定的层控 性;通过构造事件比对,明确了区内热液型重晶石与黔东隆起密切相关,推测为黔中隆起初期古断裂活 化,含矿热液上移的产物,在找矿勘查中应重视古断裂的识别;从统计角度出发,扬子地台南东缘低温热 液型重晶石矿不仅存在于传统认知的 NW向断裂中,也存在 NNE、NE、NWW、NW等多个方向,勘查工作中 应进行综合考虑。 |
| 英文摘要: |
| According to exploration practice statistics,the low-temperature hydrothermal barite deposits onthe southeastern margin of the Yangtze Platform are mainly concentrated in the tensile fractures of brittle limestoneswithin the Early Ordovician Honghuayuan Formation(O1h) and Tongzi Formation(O1t). These deposits are confined by the overlying shale of the Ordovician Dawan Formation(O1d)and the underlying shale of the Tongzi Formation(O1ty), indicating a certain degree of stratabound control. Through comparative analysis of tectonic events,it is determined that the hydrothermal barite deposits in the region are closely associated with the QiandongUplift. It is inferred that these deposits were formed by the reactivation of ancient faults during the early stage ofthe Qianzhong Uplift,which facilitated the upward migration of ore-bearing hydrothermal fluids. Therefore,the identification of ancient faults should be emphasized in mineral exploration. From a statistical perspective,low-temperature hydrothermal barite deposits on the southeastern margin of the Yangtze Platform are not only found intraditionally recognized NW-trending faults but also occur in multiple orientations,including NNE,NE,NWW, and NW directions. Thus,comprehensive consideration of various fault orientations is essential in exploration work. |
