ON THE COMPACTION CHARATERISTICS OF MUDSTONES IN THE MESO-CENOZOIC PETROLIFEROUS BASINS OR DEPRESSIONS OF THE EAST CHINA

Based on the properties of the porosity, clay mineral and the pore fluid pressure of the mud-stones, the durations for the mudstone compactions of the Meso-Cenozoic of Shanshui petroliferous Basin,and the Miyang and the Huanghua depressions can be divided into four stages respectively. In this paper,it summarizes the differences and similarities,as well as the genesis among the basin and the depressions on the basis mentioned above.
