《Petrological and Os Isotopic Characteristics of Zedong Peridotites in the Eastern Yarlung–Zangbo Suture in Tibet》
Note:*Mg#=Mg2+×100/ (Mg2++Fe2+)
Whole-rock geochemical data of the Zedong peridotites are presented in Table 3.The loss-onignition(LOI)values of of these peridotite samples vary between 0.23–1.87wt%for lherzolites and harzburgites and 2.64–2.73 wt%for dunites,which indicate that the lherzolites and harzburgites are relatively fresh,whereas the dunites arepartly serpentinized.After recalculated the data on LOI free basis,Zedong peridotites have Mg O=42.70–50.58wt%,Fe2O3=0.28–2.00 wt%,Al2O3=0.22–1.93 wt%,Ca O=0.25–2.05 wt%,Na2O=0.05–0.10 wt%and Ti O2=0.01–0.03 wt%.All peridotites show relatively linear increases in Ca O,Al2O3 with decreasing Mg O(Fig.7).
