Geosphere, August 2011, v. 7, p. 1013-1061, doi:10.1130/GES00627.1, Supplemental File 3 - PDF file of geochemistry of granitoid samples. (A) QAP (quartz-alkali feldspar-plagioclase feldspar) diagram for granitoid samples generated using whole-rock major element data. CIPW norms were calculated for each sample and projected on the diagram. All samples plot within (or on the edge of) the granite field, with the exception of one Baragaon sample that plots within the granodiorite field. (B) AFM diagram for granitic samples; A = K2O + Na2O; F = Fe2O3 + FeO; M = MgO. Curve for calc-alkaline and thoeliitic division is from Kuno (1968). (C) Geochemical discrimination diagrams for granites after Pearce et al. (1984). VAG—volcanic arc granite; syn-COLG—syncollisional granite; ORG—ocean ridge granite; WPG—within-plate granite. (D) Table of geochemical data for granitoid samples. File size is 2.2 MB.
