| 摘 要： | 本文通过对南京汤山上震旦统及古生界不同层位白云岩的岩石学特征，微量元素特征的研究提出了该区白云岩的五种成因机理，它们是原生－准同生白云石化模式，成岩早期混合水白云石化模式，成岩早期白云石化，成岩中晚期调整白云石化模式和构造热液白云石化模式。

| Abstract: | The dolostones appear in the Upper-Sinian and the Paleozoic, Tangshan, NanJing.By means of the analyses of petrology and trace element geochemistry of the dolostones, five types of do1ostone origin are described in this paper. They are the dolomitization model in the autogenetic-metasyngenetic stage, the mixed water dolomitization model in the early diagenetic stage, the dolomitization model in the early-middle diagenetic stage, the adjusting dolomitization in the diagenetic stage and the structure hot liquid dolomitizatioh model. |
