With this evidence we can deduce details of the sequential formation process from intrusion through emplacement to crystallization/solidification. Serial growth events have been identified by: 1) a study of the internal structure of zircon using cathodoluminescence observation, 2) crystallization temperatures using Ti-in-zircon thermometry of the internal structure, and 3) UPb age dating of the internal structure. This paper expounds a procedure for quantitatively determining the titanium concentration in zircon and the results of crystallization temperature measurements based on a Ti-in-zircon thermometer. The magmatic zircons collected from Toki granite display two different internal structures: LLC (low luminescence core) and OZ (oscillatory zonation). The LLC crystallized due to interfacial reaction-controlled growth with the cooling granitic magma under temperature conditions ranging from about 910\u2103 to about 760\u2103. The OZ developed due to diffusion-controlled growth within a cooling magma chamber under temperature conditions from about 850\u2103 to about 690\u2103.\u30ab\u30bd\u30fc\u30c9\u30eb\u30df\u30cd\u30c3\u30bb\u30f3\u30b9\u8c61\u89b3\u5bdf\u306b\u57fa\u3065\u304f\u30b8\u30eb\u30b3\u30f3\u306e\u5185\u90e8\u69cb\u9020\u306e\u5206\u985e\uff0c Ti-in-zircon\u6e29\u5ea6\u8a08\u3088\u308a\u5185\u90e8\u69cb\u9020\u3054\u3068\u306e\u7d50\u6676\u5316\u6e29\u5ea6\u306e\u6c7a\u5b9a\uff0c\u5185\u90e8\u69cb\u9020\u3054\u3068\u306eU-Pb\u5e74\u4ee3\u306e\u6c7a\u5b9a\u3092\u7d44\u307f\u5408\u308f\u305b\u305f\u7814\u7a76\u306f\uff0c\u6642\u9593\u30fb\u6e29\u5ea6\u306e\u89b3\u70b9\u304b\u3089\u30b8\u30eb\u30b3\u30f3\u306e\u6210\u9577\u30d7\u30ed\u30bb\u30b9\u3092\u660e\u3089\u304b\u306b\u3059\u308b\uff0e\u672c\u8ad6\u6587\u3067\u306f\uff0c2016\u5e74\u306bJournal of Mineralogical and Petrological Sciences\u306b\u516c\u8868\u3055\u308c\u305fYuguchi et al.
