| Abstract: | Every research respects of nodular limestones are summarized. Especially the following research respects: the meanings for studying nodular limestone, the definition, the denomination and the classification of nodular limestone, are discussed in detail. The sedimentary environment of nodular limestone formation is different. They can be formed in from deep sea to shallow sea, in land even as loess and desert which are quite arid. The mechanisms of nodular limestone formation are mainly as following:depositing -cementing , early burying - diagenetting, bottom current dissolving - concreting, pressure - dissolution, slippaging and bio -boring, etc. |
