摘要
武当隆起西缘广泛出露南华纪武当岩群、耀岭河组地层,为陆内裂谷环境下形成的火山—碎屑岩沉积。耀岭河组出露范围分布有条带状的Co、Mn化探异常,并伴有锰(钴)矿床(点)。通过对南华纪地层的岩性组合及成岩年代、岩相古地理、地球化学、矿产等特征分析,认为南华纪武当隆起西缘为裂谷环境,大塘坡期存在系列受裂谷控制的浅海—陆棚相滞留盆地,与湖北长阳—湖南—贵州—广西大塘坡式锰矿沉积环境类似,耀岭河组中的锰(钴)矿床(点)在华南大塘坡期成锰事件形成,具有较好的找矿潜力。
The Nanhuan period Wudang group,Yaolinghe formation widely occurring in Western Wudang uprift,which is a suit of volcanic rock and clastic depositional formed in intracontienental rift environment.The banded geochemical anomaly of Co and Mn in the exposed area of Yaolinghe formation,while corresponding Manganese(Cobalt)deposit(ore spot)exist.According to the synthetic study of the characteristics of lithological association,diagenetic age,lithofacies paleogeography,geochemistry,mineral in Nanhuan period,shows that Western Wudang uprift formed in rift environment.A series of neritic-shelf facies stagnant basin controlled by rift existed in Datangpo Stage.Similar to the Manganese deposit sedimentary environment in Hubei Changyang-Guizhou-Guangxi,which formed in Datangpo Stage Nanhuan period mineralization events,which has exporation potential and good prospecting potential.
