白云岩成因研究现状及进展

白云岩成因的研究目前还处于假说阶段,主要包括蒸发、渗透回流、海水、混合水以及埋藏白云岩化作用五种 模式。其分类方法主要依赖于地球化学特征的研究,包括阴极发光、电子探针、碳氧同位素、稀土元素以及X射线 衍射分析。伴随着计算机及模拟试验水平的提高,未来白云岩成因的研究将会结合实际地质条件,设计合理的参 数和模型,用计算机模拟的手段加以展现。

Present situation and progress of research on dolomite genesis

The research on dolomite genesis is in postulation stage at present, which includes five models of vaporization, infiltration and circumfluence, sea water, mixing water and buried dolomitization. The classification method depends on mainly the study of geochemical characteristics, which includes cathodeluminescence, electron probe, carbon-oxygen isotope, rare earth element and X-ray diffraction analysis. With the development of computer and simulation experiment level, the research on dolomite genesis will contact with the practical geologic conditions, design the reasonable parameters and models, and present through computer simulation.
