The molecular fossils characteristics of Cambrian heavy oil in Tadong 2 well were studied by the synthetic methods such as carbon isotope,GC and GC-MS.

As a newly developed subdiscipline of stratigraphy,molecular stratigraphy focuses on a variety of molecular fossils derived from biochemicals including protein,nuclear acids,carbohydrates,lipids and lignin.

Series of molecular fossils, including n alkanes, extended tricyclic terpanes, hopanes and regular steranes, have been detected from the red clastic strata of Middle Jurassic-Early Cretaceous in Jianmenguan profile, Sichuan basin in China.

Features of molecular fossils at the Shibei dinosaur fossil site-Early Jurassic red beds-in Gongxian, Sichuan, and their paleoenvironmental significance;

The spacial variations of organism derived from the molecular fossil in the typical monsoon region;

To construct the information system of molecular fossils based on Web will provide an information platform released on the Internet for worldwide researchers of organic geochemistry and molecular paleontology to retrieve and communicate rapidly.
