Abstract
- Meaning of chronological data for petrological studies was reviewed. Mizutani and Shibata (1983) estimated duration of lithification after initial deposition of sediment as 17 million years using a combination of radiolarian fossil and 87Rb-87Sr whole rock isochron ages. Harayama (1992) reported a youngest exposed granitoid pluton on Earth from the Northern Alps, central Japan, based on the K-Ar hornblende and biotite ages, Rb-Sr biotite age,and fission track zircon age. Metamorphic rocks generally record ages of many equilibrium stages during metamorphic evolution. Katayama (2004) confirmed five stages of zircon growth in ultra-high pressure metamorphic rocks from the Kokchetav massif,and estimated their exhumation speed as 0.5-0.6 cm/year using Secondary Ion Mass Spectrometry.<br />名古屋大学年代測定総合研究センターシンポジウム報告
