| 摘 要： | 对我国首次发现的海南排浦现代白云岩的研究认为，该岩发育于早更新世湛江组滨海相细—粉砂层之中，通过交代作用形成具雾心亮边结构的菱面体自形晶，矿物上属钙过剩的含铁白云岩，其形成过程可分为二个阶段：准同生渗透回流白云岩化作用阶段；成岩混合水白云岩化作用阶段，而后一阶段可能延续至今。

| Abstract: | The dolomite of Paipu, Hainan Island, is a recent dolomite firstly discovered in China.It developed in the fine sand-silt beds of coastal factes of Zhangjiang Formation,early Pleistocene.Through alteration,the rhombohedral crystalline dolomite was formed with a fogged center and clear margin structure, and belongs to a Fe-containing,Ca-excess dolomite.The formational process of the dolomite can be subdivided into two steps:(1) meta-homogenerous dolomitization caused by permeation and return flow;(2) early diagenessis dolomitization caused by mixing water which might go on to present time. |
