The Yangfang Pluton exposed in Western Hills of Beijing is dominantly composed of biotite monzogranite, and much less quartz monzonite, alaskite and dioritic enclaves. The high-precise analyses of major and trace elements for these rocks are reported by this study. The biotite monzogranite is typical high-potassic calc-alkaline granite, and has the characteristics of Rb, Ba, and LREE enrichment, depletion of Th, U, Nb, Ta relative to LREE, and weak negative Eu anomaly.  Geological evidence and wholerock chemistry as well as geochemical discrimination diagrams indicate that the Yangfang Pluton formed during the collapse stage of orogenic evolution.
