| 1 | Geochronology and Nd and Pb isotope characteristics of gabbro dikes in the Luobusha ophiolite, Tibet显示文摘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 clinopyroxene separates from one of the rocks yields a Middle Jurassic age of (177±31) Ma (with an initial εNd(t) = +8), which provides a significant bound on the time of formation of the Luobusha ophiolite. The Nd and Pb isotopic charac-teristics of the dike indicate an Indian-Ocean-type isotopic affinity, and we conclude that the Luobusha ophiolite formed in an oceanic setting during the Middle Jurassic. | ZHOU Su MO Xuanxue J.J.Mahoney ZHANG Shuangquan GUO Tieyjing ZHAO Zhidan | 2002 | Chinese Science Bulletin2002，47，2： | 38 |
| 2 | ^(40)Ar/^(39)Ar dating for Cenozoic kamafugite from western Qinling in Gansu Province显示文摘40Ar/39Ar ages were determined for 6 phlogopite samples from a kamafugite pipe occurring in western Qinling, yielding a time span of 22 to 23 Ma for kamafugite eruption. Together with known geochronological data for the Qinghai-Tibet Plateau (QTP) and its peripheral regions, it is concluded that these Cenozoic potassic-ultrapotassic volcanic rocks are products of post-collisional volcanism. The age of the Cenozoic volcanic rocks in western Qinling partly overlaps that of potassic volcanics from the Gandise belt, reflecting the northward migration of the post-collisional volcanism in QTP. The age data not only confirm the temporal and spatial migration of post-collisional volcanism in QTP, but also provide geochronological constraints on the geodynamic set- ting at depth and the regimes of the tectonic evolution since Neogene in western Qinling regions. | YU Xuehui ZHAO Zhidan ZHOU Su MO Xuanxue ZHU Deqing WANG Yonglei | 2006 | Chinese Science Bulletin2006，51，13： | 7 |
| 3 | Experimental study on electrical conductivity of dunite at high temperature and pressure——The evidence of electrical conductivity of cold mantle in the Gaize-Lugu area显示文摘The electrical conductivities of the dunite from the Qinghai-Xizang (Tibetan) Plateau were measured with the impedance spectra method at 1.0-4.0 GPa and 643-1093 K. The experimental results indicated that activation enthalpies of the dunite are smaller than 0.9 eV, the conduction mechanism in dunite may be attributed to the mixed electrical conduction involving grain interiors and boundaries. On the basis of the results of this experiment, we can deduce that there exists cold mantle in the area of Gaize-Lugu in the Qinghai-Xizang (Tibetan) Plateau by reverse methods from the magnetotelluric sounding data (conductivity-depths profile) available for western Tibet. The result provides the present cold mantle viewpoint with strong proof on the basis of high temperature and pressure experiments. | WANG Duojun LI Heping LIU Congqiang ZHAO Zhidan MO Xuanxue GUO Tieying SU Gengli DING Dongye | 2001 | Chinese Science Bulletin2001，46，24： | 5 |

| 6 | Proton angular distribution research by a new angle-resolved proton energy spectrometer显示文摘The proton spectral and angular distributions simultaneously within the target normal direction and laser propagation direction by using an angle-resolved proton energy spectrometer are studied.For the protons generated in the interactions of 100 fs,800nm laser pulses with aluminum foil targets,the deviations of proton beam centers of different energies from the target normal direction towards the laser propagation direction are different.This is probably because of the toroidal magnetic fields generated at the rear target surface,which deflect protons transversely.As a result,protons in low energy range have large deviation angles,protons in middle energy range have the smallest deviation angles,while protons in high energy tail have large deviation angles. | SU LuNing ZHENG Yi LIU Meng HU ZhiDan WANG WeiMin YUAN XiaoHui XU MiaoHua SHENG ZhengMing SHEN ZhongWei FAN HaiTao LI YuTong MA JingLong LU Xin CHEN LiMing WANG ZhaoHua WEI ZhiYi ZHANG Jie | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，5： | 1 |
