本文依据大量的野外实际地质资料,钻孔及矿井地质资料,通过各种手段,详细研究了义马组的岩矿、原生沉积构造及其序列、古生物、粒度分布、地球化学、地球物理测井等方面的沉积特征。同时结合沉积岩体的空间几何形态及相序,首次全面而系统地论证了义马中生代煤田义马组的沉积环境,环境的空间配置及演化。 Based on a large number of actual geologic data in the field, borehole and mine geological data, various methods are used to study in detail the rock and ore deposits, primary sedimentary structures and their sequences, paleontology, particle size distribution, geochemistry and geophysical logging in the Yima Formation And other aspects of sedimentary characteristics. Combined with the spatial geometry and phase sequence of sedimentary rocks, the depositional environment, spatial distribution and evolution of the Yima Formation of the Mesozoic coalfield in the Yima were systematically and systematically demonstrated for the first time.
