- The spatial and temporal distribution characteristics of the diagenesis of the siliceous clastic sequence are controlled by a series of parameters in the early diagenesis, the middle diagenetic stage and the late diagenetic stage. The distribution of sedimentary facies, climate, detrital composition and relative sea level controlled the spatial distribution of the early diagenetic facies. The most important terrigenous sediments of early diagenesis include silicate dissolution and kaolinite formation, montmorillonite and calcareous conglomerate. In the marine and transitional sedimentary environments, early diagenesis includes carbonate precipitation, opal, microcrystalline quartz, iron containing silicates, sulfides and zeolites. The early diagenetic evolution of the ocean and over sediment developed in a predictable sequence. The middle diagenesis is affected by early diagenesis, such as temperature, pressure and composition of the basin brine. The retention time of sedimentary sequence under some burial conditions is the key to determine the time, range and mode of diagenetic change. In the middle ages, the diagenesis mainly consists of albite albite, chlorite and illite, smectite and kaolinite, and chemical compaction and carbonate cementation. Mid deep buried diagenesis still exists many questions: (1) the fluid flow and the dissolution reaction; (2) mutual transmission of mudstone and sandstone; (3) hydrocarbon diagenesis in sandstone; (4) in a fluid source and importance of secondary intergranular and diagenetic stage intragranular pore formation. The main changes in the percolation and dissolution of atmospheric water is the dissolution of kaolinite and carbonate cements in the tens to hundreds of meters below the surface.
