锰矿的形成作用和物质来源的认识大致可分为“陆源说”和“火山成矿说”。前者认为成锰环境为陆缘浅海或浅海陆棚环境,是冷水沉积(包括藻类沉积)的产物,后者认为锰矿的形成与火山喷发有关,矿化发育在火山沉积岩系中,是热水沉积的产物。贵州二叠纪地层中产有大量锰矿,分布在茅口晚期NE向的黔中台沟相带内,遵义一带已发现大小锰矿床10余个,其中铜锣井锰矿床达到大型规模。前人虽然开展了一些研究,但在成矿物质来源
The formation of manganese ore and the understanding of material sources can be roughly divided into “terrestrial” and “volcanic mineralization that ”. The former considers that the manganese-forming environment is a marginal shallow-sea or shallow-sea shelf environment and is a product of cold-water sediments (including algal sediments) that are thought to be associated with volcanic eruptions. Mineralization develops in volcanic sedimentary rocks and is characterized by hydrothermal sedimentation Of the product. There are a large number of manganese deposits in the Permian strata in Guizhou, which are distributed in the middle Guizhou-Guizhou Taizigou belt in the NE direction of Maokou. More than 10 large-sized manganese deposits have been found in the Zunyi area, with the Tongluo manganese deposit reaching a large scale. Although predecessors carried out some research, but in the source of mineralization
