This paper deals with the latest Pleistocene faulting on the Canfangying segment of the faultzone along the northern margin of the Yanqing basin from the data of one trench, three geologicprofiles, seven fault scarp morphologic profiles across the late Pleistocene deposit surface and fif-teen radiometric datings.

This paper describes the first results of the Cooperative Seismological Research Project in the Yanqing-Huailai Basin(YHB).

Pollen records and vegetation and climate changes in Heqing Basin, Yunnan Province since middle Pleistocene;

Paleoenvironmental evolution of Heqing basin in Yunnan Province since 2.78 Ma;

0 Ma,based on pollen records from the 168 m deep core in Heqing basin,Yunnan Province,southwest China.

The oil system and exploration perspective in Yanji Basin;

Radioactive anomaly character about Yanji Basin oil reservoir;

The sedimentation and oil-gas characteristics of the lower Cretaceous,Tongfosi Formation and Dalazi Formation,Yanji Basin;

In this paper, some characters of temperature, hydro-chemistry, gas-chemistry and isotope chemistry of thermal fluids in upper crust of the Yanqing-Huailai basin are studied.

Yanhuai Basin contains Yanfan Basin and Huaizhuo Basin,which are connected one another.

Based on the tectonic characteristic of Yanhuai Basin and recent slip velocity of each fault,the future seismic risk of each fault is evaluated with magnitude-time prediction model.

There was lake development during late Pleistocene in the Yanhuai basin.
