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℃ to about 760℃. The OZ developed due to diffusion-controlled growth within a cooling magma chamber under temperature conditions from about 850℃ to about 690℃.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"カソードルミネッセンス象観察に基づくジルコンの内部構造の分類， Ti-in-zircon温度計より内部構造ごとの結晶化温度の決定，内部構造ごとのU-Pb年代の決定を組み合わせた研究は，時間・温度の観点からジルコンの成長プロセスを明らかにする．本論文では，2016年にJournal of Mineralogical and Petrological Sciencesに公表されたYuguchi et al.
