Formation mechanism of authigenic chlorite and relation to preservation of porosity in nonmarine Triassic reservoir sandstones, Ordos Basin and Sichuan Basin, China;

Numerous published studies have shown that the authigenic chlorite grain coatings can inhibit the quartz cementation,but the mechanism is still unclear.

The authigenic chlorite grain-coatings or pore-linings play an important role in preserving primary porosities effectively by resisting the compaction of the overlying rock and decreasing the number of nucleation of authigenic quartz on the surfaces of grains in reservoir sandstones of Xujiahe Formation,Sichuan basin,China.

Differing from the ancient and modern known palaeochannel-type exogenetic-epigenetic uranium deposits, Malinov uranium deposit has developed strong chloritization for several times.

The muscovite-chlorite geothermometer,muscovite-biotite geothermometer and chlorite compositional geothermometer that are suited to the low-temperature conditions have only been used in the interpretation of regional metamorphis.

And the influence on the separation efficiency of hydrocyclone was studied owing to the physical property and the petroleum chemical ingredient of the residue.
