摘要
依据地层学的对比研究,云南格学、贵州水城———纳雍和遵义的锰矿均产于中二叠统茅口晚期黔中台沟相带的茅口组第二段,它们在同一成矿地质背景下,其矿床地质特征相似,物质来源相同,具有一定亲缘关系的可比性。该区(带)的锰矿,主要受被动大陆边缘强烈拉张及同生沉积断裂作用,茅口晚期黔中台沟相带和基性火山喷发活动,以及硅灰泥锰矿组合等条件的严格控制。
Through a comparative study in stratigraphy, the manganese ores at Gexue of Yunnan, Shuicheng-Nayong and Zhunyi of Guizhou homogeneously occurred within the Second Member of the Upper Maokou Formation as platform and trench facies zone in the central part of Guizhou, among which geologic features of the deposits are resemble and material sources are identical with certain original comparability. The manganese ores at this zone are primarily dominated by the terms including continental marginal intense stretching and syngenetic sedimentation faulting, the platform and trench facies and basic volcanic eruption activities of the Upper Maokou Formation in the central part of Guizhou, and the severe control by the combination of manganwollastonite ores.
