摘    要:广西二叠纪沉积岩石类型有碳酸盐岩、碎屑岩、铁铝质岩、硅质岩及火山碎屑沉积岩等5种类型。古生物计有19个门类,553属,132带(组合),1313种。沉积海域分属陆地-陆缘滨岸相、陆缘碳酸盐台地或碳酸盐缓坡相、弧立碳酸盐台地相、台地边缘相、台缘斜坡-浅水盆地相和半深水-深水盆地相等不同的沉积环境。其沉积古地理格局严格受岗瓦纳板块南移、碎裂和特提斯海的扩张影响,可分为石炭纪泛大陆晚期发展阶段(马平晚期

关 键 词:二叠纪 沉积 矿产资源 岩石地层 生物地层

Abstract:The Permian sedimentary rocks in Guangxi include carbonate rocks, elastics rocks, ferruginousbauxitic rocks, siliceous rocks, and pyroclastic rocks. The Palaeobiococnosis has 19 biotype, 553 genera, 132 zone (association) and 1313 species. The sedimentary facies are put under continental-continental edge littoral facies, continental edge carbonate platform facies or carbonate ramp facies, isolated carbonate platform factes, edge facies of platform, slope facies on edge of platform-shallow basin facies and half deep-deep basin facies. Its sedimentary paleogeographic structure strictly received a tremendous influence from Gondwana Plate movement to south,breaking, and Tethys Sea floor spreading. Its revolution can be divided into Carboniferous Period Pangea late development stage (Maping late period),Pangea broken or Tehys sea resolved stage (Qixia period), Tethys sea development stage (Maokou periad), Tethys sea floor spreading to Triassic Period deep basin revolution stage (Zhangxing period). There are 21 types of mineral resources in over 300 spots, including 9 large mineral deposits and 10 middle mineral deposits.
Keywords:permlan stratum   sedimentary paleogeography   mineral resources
