High Mg# of the continental crust explained by calc-alkaline differentiation
《National Science Review》2023年第3期86-93,共8页Ming Tang Xuanyu Liu Kang Chen 
financially supported by National Natural Science Foundation of China (42125302, 42073026, 41888101 and42073024);the support from the Xplorer Prize。
We used compiled geochemical data to investigate the mechanisms that control Mg#(molar ratio of Mg/(Mg+Fe_T)) in andesitic arc lavas.We find that andesites from mature continental arcs with crustal thickness of>45 km ...
