| 摘 要： | 白云岩的成因可分为准同生期、成岩期和成岩期后等三种成因类型，但其成因机理则是长期悬而未决的问题。经过多年对白云岩的深入研究，已提出了多种不同的成因模式（如渗透回流、蒸发泵吸、混合水、调整白云岩等模式），对特定环境中形成的白云岩可以作出圆满解释。江西萍...

| Abstract: | In this paper,through the analysis of oxygen and carbon isotope of dolomite of mid Carboniferous Huanglong group in weste rn Pingle trough, discrepancy of oxygen and carbon isotope values between silt siz e and fine coares size dolomite obviously existed and the salinity and temper ature in which dolomite was formed have reckoned by oxygen values. This reflected that dolomite was formed in different sedimentary environments and diagenetic stag es. Silt size dolomite had the feature of parasyn genetic dolomite under fas t diagenesis in the hypersaline seawater environment, fine eoares size dolomite had the feature of diagenetic dolomite under sluggish crystallization in the mixture water. |
