The outcrops of Khangai Granite in Mongolia

  This granite is widely exposed in Khangai Mountains of central Mongolia. It is mainly composed of meidum- to coarse-grained hornblende bearing biotite quartz monzodiorite, and belongs to ilmenite-series granitoids. The isotopic age shows latest Permian (see article in this volume by Takahashi et al.). This photograph was taken during the excursion of IGCP420“Continental Growth in the Phanerozoic: Evidence from Central Asia”in July, 1999.
