摘要： 基于白云石晶体的成核动力学和生长动力学理论,将白云岩岩石结构按晶体大小和晶边形貌进行划分。白云石结构的演化主要受原岩化学组成、沉积结构和白云岩化流体的影响。可将原岩分为不同化学组分的泥灰岩和含颗粒泥灰岩,按不同结构组分进一步划分为含溶孔、胶结物和泥晶化的泥灰岩和含颗粒泥灰岩。在不同浓度的白云岩化流体中,讨论了白云石结构的演化。

Abstract: Based on the nucleation and growth kinetics theory, the dolomite structure can be classified in terms of crystal size and crystal edge shape. The evolution of the dolomite structure is controlled by the chemical composition and deposit texture of primitive rocks and dolomized fluid. The primitive rocks can be classified into the muddy limestone and muddy limestone with grains in terms of chemical component and the limestone with dissolved pore and cement, micritic limestone and muddy limestone with grains in terms of structural composition. The evolution of dolomite structure is discussed in condition of varied concentration dolomized fluid.

Key words: dolomite, texture/structure evolution, chemical kinetics, dolomized fluid
