1·As cement, authigenic mineral or vein, dawsonite is found not only in Marine dolomite and oil shale, but also in terrigenous fragmentary rock and coal measures.
片钠铝石作为胶结物、自生矿物或脉体，不仅分布在海相白云岩、油页岩中，而且还广泛分布在陆源碎屑岩及煤系地层中。
2·As the main flow manner of formation water in deep reservoir, circulated convection current controlled authigenic mineral location and secondary pore distribution.
循环热对流是深部储层流体的主要流动方式，它控制着自生矿物在砂层中的析出位置和次生孔隙的分布特征。
3·Carbonate could be precipitated as authigenic calcite mineral in the pores in case of that pore has enough HCO 3 - ions since mudstone should be an enclosed system.
泥岩是一种较好的“封闭体系”，当孔隙水中有大量的HCO - 3来源时，其中的碳酸盐沉淀形成自生方解石矿物。
4·Based on the authigenic and clay mineral assemblage, two types of diagenetic ambient have been recognized in the meso - cainozoic detrital rocks in tarim basin.
根据自生矿物与粘土矿物组合，在塔里木中新生界碎屑岩中可以识别出两种成岩环境。
5·Cementation is showed by the secondary enlargement of quartz and feldspar, the successive formation and pores filling of cementing material of authigenic clay mineral, calcite and anhydrite, etc.
胶结作用表现为石英和长石的次生加大、自生粘土矿物、碳酸盐和硬石膏胶结物的依次形成并充填孔隙。
