| 摘 要： | 主要研究华力西—印支期海相沉积盆地演化,从古地理、沉积相和地层时代几个关键因素出发,结合广西下雷锰矿床的地质特征,分析了盆地演化的几个重要因素与下雷锰矿床的成矿关系。认为华力西—印支期为锰矿床沉积的重要时期,而晚泥盆世为下雷锰矿床的地层年代控矿因素,硅质岩—碳酸盐沉积相为矿层层控特征,下雷浅海盆地的差异性沉降和断裂作用,是形成下雷锰矿巨型矿床的关键原因。

| Abstract: | The author mainly talks about the Variscan period marine sediment in basin evolution,ancient geography,sedimentary facies and geological age in several key factors,by combining Xialei manganese ore deposit with geological characteristics to analyse the basin evolution of several important factors,including the metallogenic relation of Xialei manganese ore.This paper argues about the Variscan period for manganese deposits in its important period,while the late Devonian is the formation time deposit ore in controlling factors of Xialei manganese ore.And siliceous rocks carbonate are sedimentary facies for seam stratabound features,ray shallow basin differential subsidence and fracture effect,all are formed under the key cause of giant ore deposits in Xialei. |
