However,owing to the absence of vitrinite determined the maturity indicator in the Lower Paleozoic source rocks,the zooclast reflectance can't be correlated directly with t.

Through the grain-size analysis of scraps of the rock mass that was produced in the test of collapse in laboratory and in the test of gradual collapse in field atmospheric con.

Through grain-size analysis of scrap for soft rock that was produced during test of collapsing in laboratory and test of gradual collapsing in field atmospheric condition; it was found that absorbing water and collapsing progress of soft rock is also a progress that fractal dimension of soft rock scrap change successively.

The quantitative analysis of mineral detritus in 13 surface sediment samples from the Quanzhou Bay was made, and it is shown from the analysis results that the compositions, contents and characteristics of light and heavy minerals at different stations in the Quanzhou Bay are different from each other.

Research of detrital minerals in the sediment of sub-aqueous Yangtze Delta;

The study of the detrital minerals of Changjiang sediments indicates that the light minerals mainly consist of quartz,feldspar and lithic fragment.

The changes of detrital mineral contents with water depth, land-form and physiognomy indicate that the distribution of minerals is mainly affected bylandform and physiognomy, and the affecting factors are complicated.

Distribution of clastic minerals of surface sediments in the western China Sea and their provenance;
