Laser ablation inductively coupled plasma mass spectrometry was used to perform U-Pb dating on zircons from granitic rocks in the Hida Mountain Range, central Japan. Samples were targeted for dating that showed a marked difference in cooling age across the Takasegawa Fault (Ito and Tanaka, ). The Okukurobe granite to the west of the fault, and the Oshirasawa granite to the east of the fault, yielded ages of .. Ma and . . Ma, respectively. These ages imply that both granites were intruded at the same time (ca. Ma). The Oshirasawa granite has a mylonitic texture, which probably reflects rapid uplift and erosion by faulting in the past Myr. The Kanazawa granodiorite to the east of the Takasegawa Fault was dated as .. Ma, indicating that this pluton was intruded in the Quaternary. In addition to the Takidani granodiorite, this is the second confirmed occurrence of an outcropping Quaternary pluton in the Hida Mountain Range.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
