Natural and surfactant-modified geomaterials (such as zeolite, bentonite, dacite and rhyolite) were used to remove chlorohydrocarbons from wastewater in this paper.

The views on the metallogenetic series of China porphyry deposits;

Based on generation relation of diagenetic minerals, fluid inclusion and fluorescence detection,the history of fluid activity and oil charging is reconstructed for reservoirs of Shasi Member located at depth of 1 600 m~2 700 m and 2 700 m~3 000 m.

The accumulation properties of the reservoirs are mainly controlled by diagenetic mineral facies belts.

Its applications were discussed in the analyses and research of basin fluid diagenetic mineralogical age, fluid field character, evolution of formation water origin, reservoir heterogeneity, fluid movement trace, temperature and salinity of ancient fluid, distinguishing between sea facies and lake facies, diagenetic environment.
