湖南省沉积型锰矿地质环境及成矿作用
|
摘要
湖南省沉积型锰成矿时代跨度大,最早由早元古代板溪群马底驿期至早二叠世孤峰期。其中,早南华纪大塘坡期、中奥陶世烟溪期及中二叠世孤峰期为三个最主要成锰集中期,并且大体呈现出朝东南方向成矿时代变新的趋势。成锰沉积盆地是锰矿床就位的重要场所,相应的岩相古地理环境为锰成矿创造了有利条件,即相对缺氧的、滞流的安静环境。这种环境在诸多古地理环境中都可以形成,导致了锰成矿岩相古地理环境的多样性,如浅海陆棚相、次深海棚缘盆地相、次深海台缘斜坡相及陆表次深海海盆相。三个主要成锰期锰成矿作用具有统一性,成矿作用与地壳拉张、海侵事件、缺氧事件等区域性重大地质事件关联密切。
The sedimentary manganese mineralization in Hunan spanned a large age,from the Madiyi period of early Proterozoic to the Cufeng period of middle Permian.Of it,the Datangpo of early Nanhua,Yanxi of middle Ordovician and Cufeng of middle Permian are 3 dominant periods of concentrating manganese mineralization.In addition,the mineralization ages roughly tend to be younger towards southeast.Manganese-forming sedimentary basins accommodate manganese precipititating.The sedimentary facies of these basins are favorable to manganese mineralization because they have created an anoxic,stagnant and quiet environment.In fact,such environments can be formed in many plaeo-geographical settings,which leads to manganese-forming sedimentary facies diversity,such as shallow marine shelf,bathyal shelf margin basin,bathyal platform-margin slope and continental bathyal basin related to Hunan sedimentary manganese mineralization.Meanwhile,it is concluded that the 3 periods of manganese mineralization have consistency,which are associated with crustal extension,transgression,and anoxic events in this region.
