| Abstract: | In this paper,the lithology and geochemistry characters of carbonate lens which occurred in Jiumenchong formation,Lower Cambrian is narrated,the analysis shows that the genesis is unusual sediment-crust-mantle mixed hydrothermal exhalative sediment.New information and acknowledge are afford for the searching of crust-mantle mixed hydrothermal mineral and the study of sedimentary environment in this period. |
