-strata profiles within the depths of several tens meters or more.

Quaternary stratigraphic section along the Changhong Highwayin Jiujiang Jiangxi;

Based on the mathematical theory of analytical geometry of three dimensions and computer graphics, the paper does some important research on the integration plot for well track and stratigraphic section and borehole log.

The establishment of the stratum section database and the symbol database of lithology based on GIS;

This paper introduces a program about data processing of stratum section surveying The program not only can process data of stratum section surveying in field but also can make those data processing results into point files and line files for drawing Those data can be introduced into MAPGIS (a soft that made in China

Linkage interpretation between chronostratigraphy and relative change of sea (lake) level,;

Revision was made on the earlier proposed chronostratigraphy of South China.

Analyses of the two boreholes include OSL and U-series dating,pollen and microfossils,tending to reconstruct the high resolution climatic stratigraphy,and therefore to define the chronostratigraphy of the Late Quaternary.
