Zircon U-Pb dating of the Nanyili granodiorite in the Pingwu area, northwestern Sichuan, and its geological significance;

SHRIMP U-Pb zircon dating of granodiorite in the Kangrinboqê pluton in western Tibet, China and its geological implications;

SHRIMP U-Pb dating of zircons from the east Dayanchi granodiorite, East Tianshan, Xinjiang, China;

Mesozoic granodiorites occurring in southwestern Fujian, whose ages are 183～162 Ma and 108～106 Ma respectively, belong to high_K calc_alkaline series of intraplate with K 2O+Na 2O>6.

SHRIMP U-Pb dating of zircons from granodiorite porphyry gravels in a conglomeratic lithic sandstone sample from this suite of rocks yields a weighted mean age of 314.

During the late stage of reverse napping,granodiorite porphyry emplaced along the nappe structure and hydrothermal ore-forming solution accumulated and formed gold deposits at favourable positions.

In this paper,the data of the uniaxial compressive strength of porphyritic granite at micro-new status is analyzed from the experiment of the Three Gorges Project,in which the time span is from April in 1956 to May in 1999.
