| Abstract: |
| The main factors that affect abundance of organic matter in marine source rocks include origin of organic matter, productivity of organism, sedimentary environment. The minor factors are sedimentary velocity and mineral effect of organic matter and other factors are microelement, physiochemisty, preservation condition, organic matter evolution etc.. Study result ravels that higher abundance of organic matter is from dinoflagellates and coccolithes, which usually have larger than 1%～2% of . Marine organic matters have high enrichment degree in high-lifeproductivity areas. Most of marine source rocks are formed in such deoxidized environment as alkalescence salt water and weak water dynamics. |
