摘要
介绍了武汉都市发展区范围内地壳从海相沉积过渡到陆相沉积、历时近八亿年地球演化过程中形成的28组组级地层单元,分析了其岩土组合特性。这些地层与4界(代)、11系(纪)、17统(世)地质年代相关。文中分析可供城市区域地质调查、工程地质、城市地质信息化建设等参考。
The features of 28 formation units are introduced in Wuhan urban development zone.The earth-crust development last nearly eight hundred million yearsfrom its oceanic sediment to continental sedimentin the earth evolution,related with geological time scale of 4 Erathems(Eras),11 Systems(Periods) and 17 Series(Epoches).The results from this paper are useful for regional geology,engineering geology and geological data informatization.
