Three types of amphibolites were found around a large serpentinite body in the basement of the Ohmachi Seamount in the Izu-Bonin-Mariana arc: epidote-albite amphibolite, epidote-garnet amphibolite, and garnet-zoisite amphibolite. The epidote-albite a

The Mae Ping shear zone (MPSZ) is one of the major ductile strike-slip systems associated with the Cenozoic extrusion tectonics in Southeast Asia. However, its sinistral shear lacks a robust temporal constraint. This study attempts to acquire the def

Publikováno v: Journal of Asian Earth Sciences. 167:103-129

This study presents new whole-rock geochemical and Sr-Nd isotopic data, together with zircon U-Pb ages and Hf isotope ratios, of granitic rocks and associated dikes from the Okhotsk and Aniva plutons in South Sakhalin. The two plutons emplaced in the

Publikováno v: Journal of Asian Earth Sciences. 109:1-19

Major and trace elements and whole rock Sr–Nd isotope data of Late Permian silicic plutonic and volcanic rocks from the Phan Si Pan–Tu Le region in NW Vietnam were collected in order to establish their petrogenetic relationship with the magmatic

A lower crust origin of some flood basalts of the Emeishan large igneous province, SW China

Autor: Han Yi Chiu, Tadashi Usuki, J. Gregory Shellnutt, Allen K. Kennedy

Publikováno v: Journal of Asian Earth Sciences. 109:74-85

High seismic velocity layers within the lower crust (i.e. ∼40 km) of the Yangtze Block are interpreted as mafic underplated rocks derived from the Late Permian Emeishan mantle plume. However, the region experienced a previous magmatic event during

Zircon U–Pb ages and Hf isotopic compositions of alkaline silicic magmatic rocks in the Phan Si Pan-Tu Le region, northern Vietnam: Identification of a displaced western extension of the Emeishan Large Igneous Province

Autor: Kuo-Lung Wang, Ching Ying Lan, Sun-Lin Chung, Tadashi Usuki, Trong-Hoa Tran, Gregory Shellnutt, Thi Dung Pham

Publikováno v: Journal of Asian Earth Sciences. 97:102-124

In-situ zircon U–Pb and Hf isotope analyses were carried out for alkaline silicic magmatic rocks from the Phan Si Pan-Tu Le region in northern Vietnam to constrain their possible sources and to determine their petrogenetic relationship with the Eme

Publikováno v: International Geology Review. 56:1932-1944

Nephrite in the Fengtien area of the eastern part of the Central Mountain Range, Taiwan, is associated with antigorite-serpentinite within the Yuli belt, a late Cenozoic subduction–accretionary complex related to the eastward subduction of the Sout
