《"Petrogenesis of Late Cretaceous Jiangla'angzong I-Type Granite in Central Lhasa Terrane, Tibet, China: Constraints from Whole-Rock Geochemistry, Zircon U-Pb Geochronology, and Sr-Nd-Pb-Hf Isotopes"》
Jiangla’angzong syenogranite and adamellite Rb-Sr,Sm-Nd,and Pb isotopic compositions are listed in Table 6and Fig.6.The 87Rb/86Sr ratios ranged from1.8780 to4.6441,the 87Sr/86Sr ratios ranged from 0.7106 to 0.7180,the 147Sm/144Nd ratios ranged from 0.1015 to 0.1086,the143Nd/144Nd ratios ranged from 0.5121 to 0.5123,the206Pb/204Pb ratios ranged from 18.758 to 18.828,the207Pb/204Pb ratios ranged from 15.698 to 15.709,and the208Pb/204Pb ratios ranged from 39.218 to 38.280.Analytical results show that these mineral grains have homogenous Rb-Sr,Sm-Nd,and Pb isotopic compositions.The(87Sr/86Sr)t ratios ranged from 0.7106 to 0.7179,the(143Nd/144Nd)t ratios ranged from 0.5121 to 0.5123,the(206Pb/204Pb)t ratios ranged from 18.683 to 18.746,the(207Pb/204Pb)t ratios ranged from 15.695 to 15.702,(208Pb/204Pb) t ratios ranged from from 39.012 to 39.071,and theεNd(t)ranged from,-10.17 to-6.10.
