《Late Triassic Granites From the Quxu Batholith Shedding a New Light on the Evolution of the Gangdese Belt in Southern Tibet》
Whole-rock major and trace element compositions are presented in Table 4.The Daga granitic pluton has variable Si O2 contents ranging from 67.5 to 71.92 wt%and low K2O+Na2O contents ranging from 4.41 to 5.86wt%，respectively.The Rittmann Indexδranges from 0.73to 1.34（meanδ=1.00<3.3），indicating a calc-alkaline rock affinity[δ=（Na2O+K2O）2/（Si O2-43）].The analyzed samples have low LOI between 0.72 and 1.14（mean 0.85）（Table 4） ，confirming that the Daga granite is largely unaffected by hydrothermal alteration，as previously documented in petrographic thin sections.
