Autor: Bor-ming Jahn, Atsushi Utsunomiya, Hironao Shinjoe, Kazuaki Okamoto, Tsutomu Ota

Publikováno v: Chemical Geology. 280:97-114

New geochemical and Sr–Nd isotopic data for the Iratsu eclogite and surrounding metamorphic rocks of the Sanbagawa belt, Japan, show that, while the protoliths of the metamorphic rocks formed in a variety of tectonic settings, the Iratsu body repre

A geochemical and Sr–Nd isotopic study of the Vendian greenstones from Gorny Altai, southern Siberia: Implications for the tectonic setting of the formation of greenstones and the role of oceanic plateaus in accretionary orogen

The Central Asian Orogenic Belt is considered to be the most important site of juvenile crustal formation since the Neoproterozoic. Gorny Altai of southern Siberia represents the first stage of tectonic evolution in the Central Asian Orogenic Belt. G

Publikováno v: Gondwana Research. 16:587-608

Plume-related oceanic magmatism form oceanic islands, seamounts and plateaus (hereafter “seamounts” or “paleoseamounts”), which are important features in geological history. The accretion of oceanic seamounts to active continental margins sig

Preserved paleo-oceanic plateaus in accretionary complexes: Implications for the contributions of the Pacific superplume to global environmental change

Autor: Tsutomu Ota, Norihito Suzuki, Atsushi Utsunomiya

Publikováno v: Gondwana Research. 14:115-125

We have reinvestigated the mid-Cretaceous plume pulse in relation to paleo-oceanic plateaus from accretionary prisms in the circum-Pacific region, and we have correlated the Pacific superplume activity with catastrophic environmental changes since th

Geology of the Gorny Altai subduction-accretion complex, southern Siberia: Tectonic evolution of an Ediacaran-Cambrian intra-oceanic arc-trench system

Publikováno v: Journal of Asian Earth Sciences. 30:666-695

The Gorny Altai region in southern Siberia is one of the key areas in reconstructing the tectonic evolution of the western segment of the Central Asian Orogenic Belt (CAOB). This region features various orogenic elements of Late Neoproterozoic–Earl

Publikováno v: Physics of the Earth and Planetary Interiors. 146:231-242

Pb isotopic compositions of melt inclusions in olivine phenocrysts of lava samples from Mangaia and Rarotonga, Cook–Austral islands, have been determined by secondary ion mass spectrometry. The Pb isotopic compositions of melt inclusions from Rarot

The oldest mid-oceanic carbonate buildup complex: Setting and lithofacies of the Vendian (Late Neoproterozoic) Baratal limestone in the Gorny Altai Mountains, Siberia

Publikováno v: Proceedings of the Japan Academy. Series B, Physical and Biological Sciences

The Baratal limestone in the Gorny Altai Mountains, southern Siberia, occurs as large allochthonous blocks within a Cambrian accretionary complex that developed around the Siberia craton. Before the final accretion to Siberia in the Cambrian, the ter
