Journal ArticleDOI
Linking the Indochina block and Gondwana during the Early Paleozoic: Evidence from U–Pb ages and Hf isotopes of detrital zircons
TL;DR: In this paper, in-situ U-Pb and Hf isotope analyses were performed on detrital zircons from three river sediment samples in the Truong Son Belt of the Indochina block.
Journal ArticleDOI
Late Triassic–Late Cretaceous accretion/subduction in the Taiwan region along the eastern margin of South China – evidence from zircon SHRIMP dating
TL;DR: In this paper, the authors examined the tectonic history of the Taiwan segment of the eastern margin of South China, and selected six rock samples from the Tailuko belt, the metamorphic basement of Taiwan, were selected for zircon SHRIMP dating.
Journal ArticleDOI
Formation of Cretaceous Cordilleran and post-orogenic granites and their microgranular enclaves from the Dalat zone, southern Vietnam: Tectonic implications for the evolution of Southeast Asia
J. Gregory Shellnutt,Ching Ying Lan,Trinh Van Long,Tadashi Usuki,Huai Jen Yang,Stanley A. Mertzman,Y. Iizuka,Sun-Lin Chung,Kuo-Lung Wang,Wen Yu Hsu +9 more
TL;DR: The Dinhquan, Deoca and Ankroet plutons and their enclaves indicate that the Dalat zone transitioned from an active continental margin producing Cordilleran-type batholiths to highly extended crust producing within-plate plutsons.
Journal ArticleDOI
Early Paleozoic medium-pressure metamorphism in central Vietnam: evidence from SHRIMP U-Pb zircon ages
Tadashi Usuki,Ching Ying Lan,Tzen-Fu Yui,Yoshiyuki Iizuka,Tich Van Vu,Tuan Anh Tran,Kazuaki Okamoto,Kazuaki Okamoto,Joseph L. Wooden,Juhn G. Liou +9 more
TL;DR: In this article, SHRIMP U-Pb dating and REE analyses of zircon were carried out for two paragneiss samples of the Kham Duc Complex, central Vietnam.
Journal ArticleDOI
Generation of Cenozoic granitoids in Hokkaido (Japan): Constraints from zircon geochronology, Sr-Nd-Hf isotopic and geochemical analyses, and implications for crustal growth
TL;DR: In this paper, the mode of generation and source characteristics of these granitoids in order to assess the crustal composition of Hokkaido and examine the general problem of continental growth were studied.
