摘 要: | 本文以下第三系藻白云岩和奥陶系白云岩为试料、二次蒸馏水为介质,在不同温度(100~200℃)、压力(100×105~300×105Pa)和时间(7~21天)下进行成岩模拟实验.实验结果表明,白云石本身具有随温度升高以排钙和内部晶格调整的方式向理想白云石转化的内因.这一过程进行的结果是矿物自身体积缩小产生孔隙.

Abstract: | In this paper,the Lower Tertiary algal dolomite and the Ordovician dolomite are taken as sampling material and secondary distilled water as a medium.The preliminary results of diagenesis modelling experiments under different temperature(100~200℃),pressure(100×105~300×105Pa)and time(7~21 days)showed that dolomite itself has internal causes of changing into ideal dolomite with the rising of temperature in the ways of calcium-discharge action and internal lattic adjustment.The outcome of this progress is that pores emerge with the volume reduction of mineral itself. |
