Series Ⅰ(the Nanling Series)has a sequence of petrogenesis and mineralization:monzonitic granite or granodiorite→biotite granite→leucocratic granite→granoporphyry or quartz porphyry→intermediate-basic dikes;ree→...
The Gangdise rockk belt is the northmost an4 petrochemically the most complex one of the three east-west striking intermedlate-acid rock belt in south Xizang. Rh-Sr whole rock isochronous dating was conducted on sampl...
Widespread in Southern Xizang are intermediate-acidic rocks characterized by their regular distribution in space and time. In order to explore their formation ages and genesis, we have determined the Rb-Sr whole rock ...
U-Pb isotopie geological ages were determined on more than 30 specimens of zircon,feldspar, sphene and apatite from the Kangdeee rock belt and its eastern Bome-Zayu areas in Xizang (Tibet). The study of common lead de...
In view of their distinct NWW trending and their decreasing geological age from north to south, intermediate-acid magmatic rocks in the southern part of Xizang can be divided into three petrographical belts in general...
