All zircon grains analyzed exhibit concentric zoning typical of crystallization from a granitic magma. A total of 66 analyses on 12 grains yielded an isochron age of 298+/-28 Ma. This is the first chronological evidence found for the existence of post-tectonic late Carboniferous to early Permian magmatism in the Hercynian suture zone of central Asia, although granitoids of this age are widely recognized in the European Hercynian orogen. This provides a new constraint on the timing and extent of Hercynian orogenesis from Europe to Asia., 国立情報学研究所で電子化したコンテンツを使用している。}, pages = {67--73}, title = {Significance of c. 300 Ma CHIME zircon age for post-tectonic granite from the Hercynian suture zone, Bamian, Afghanistan}, volume = {18}, year = {2002} }
