Geochronology and Nd and Pb isotope characteristics of gabbro dikes in the Luobusha ophiolite, Tibet被引量：40
《Chinese Science Bulletin》2002年第2期143-146,共4页ZHOU Su MO Xuanxue J.J.Mahoney ZHANG Shuangquan GUO Tieyjing ZHAO Zhidan 
This work was supportedby both the National Natural Science Foundation of China and the National Key Project for Basic Research on the Tibetan Plateau (Grant Nos. 49772107, 49802005 and G1998040800) ; the U.S. National Science Foundation (EAR-9805318)
We report a combined internal and whole-rock Sm-Nd isochron age, and Nd and Pb isotopic data for gabbro dikes of the Luobusha ophiolite in Tibet. The Sm-Nd isochron of data for two whole rocks and plagioclase and clin...

Sm-Nd isotope study and dating on Honguleleng ophiolite in Xinjiang, China被引量：2
《Chinese Science Bulletin》1999年第20期1914-1917,共4页Zhangdong Jin Jianhua Huang Fuchun Li 
A study of the Sm-Nd isotope composition of Honguleleng ophiolite in Xinjiang, China, isochron age ((626±25)Ma),εNd(t) = 8.40,and its model age (TNdDM) in the range of 1 180-1 208 Ma, indicates that the ophiolite wa...

Sm-Nd isochron age of ophiolite along northern margin of Altun Tagh Mountain and its tectonic significance被引量：14
《Chinese Science Bulletin》1999年第5期456-458,共3页Zhaojie Guo Zhicheng Zhang Jianjun Wang 
An ophiolite belt is exposed to the northern edge of Altun Tagh Mountain. Geochronological researches were made on gabbro and basalt. Sm-Nd isochron age of gabbro is (829 ± 60) Ma, while the age of gabbro mixed basal...
