This paper discusses the scientific basis of existing Bohai rift system based upon a large number of geological and geophysical data,and comprehensively summarizes formation and evolution of the Bohai rift system.

Based on the study of well-drilling, core rock section and the results of analysis and test datum, it is determined that the main rock types in Western Area of Jing′anpu of damintun depression lying in rift system of Bohai gulf are carbonate rock and metamorphic rock.

They mainly formed in the different stratigraphic sequences of Meso- to Neo-Proterozoic rifting system.

Previous workers tried to use truncated icosahedra to explain the distribution of rifting system, anorogenic magmatism and dyke swarms of Laurentia and Gondwana in a global view.

Most of the large gold and polymetal deposits distributed in the north margin of the Yangtze platform located in the nuclei of old rift system.

The history of faulting of the Baikal rift system is esentially coincident with the associated sedimentary processes.

It is the first ecopath model which consists of 13 function groups (boxes), and only covers the main trophic flow in the Bohai Sea ecosystem.
