The Precambrian granitoid pluton emplaced in the Paleoproterozoic-Mesoproterozoic Baoban Group in Gezhen area, northwest Hainan Island, south China was dated by SHRIMP U-Pb analysis assisted by CL image.

Recommendation for the new geochemical classification scheme of granitic rocks and review for the relevant subjects;

Using LA-ICPMS,this study firstly reports magmatic zircon ages for granitic rocks from the Nansha micro-block,South China Sea.

The streaky structures of granitic rock extraordinarily develop in Tiantangshan area, they can be regarded as two types as differentiated streaky structure and transpositional-compound streaky structure according to their geneses.

Geochemistry of the Carboniferous-Permian post-collisional granitic rocks from Tianshan;

Automatic realization of the classification for granitic rocks by computer;

The distributive characters of Au content in granitic rocks from Au mineralized district inShenglidaban has been studied with fractal theory,The study indlcates that, during ductile shearactiveity,certain part of Au orebodies formed in this way is usually in large-scale,but Au grade isrelatively low and there is no distinct boundary between the orebody and its country rocks.

New evidence for the liquation mineralizing processes has been presented using two se-ries of experimental results in the granitic magmatic system.
