Late Cenozoic Cooling History of the Xigaze Fore-Arc Basin along the Yarlung–Zangbo Suture Zone (Southern Tibet): New Insights from Low-Temperature Thermochronology [PDF]

open access: yesLithosphere
The Tibetan Plateau is currently the widest and highest elevation orogenic plateau on Earth. It formed as a response to the Cenozoic and is still ongoing collision between the Indian and Eurasian plates.

Geochemical Constraints on Spatial‐Temporal Distribution and Origin of Anomalous Mantle in the Western Pacific Basins

open access: yesGeochemistry, Geophysics, Geosystems
Seafloor basalt samples recovered from the Caroline Basin (CB), the Parece Vela Basin (PVB), and the Western Philippine Sea Plate (WPSP) are analyzed for whole‐rock major and trace elements (including H2O), Sr‐Nd‐Pb‐Hf isotopes and 40Ar‐39Ar age‐dating ...

Geology of the Cenozoic Indus Basin sedimentary rocks : paleoenvironmental interpretation of sedimentation from the western Himalaya during the early phases of India-Eurasia collision. [PDF]

open access: yes, 2010
This study reassesses the stratigraphy, sedimentology, and provenance of the Indus Basin sedimentary rocks, deposited within the Indus Tsangpo Suture Zone (ITSZ) during the early phases of India‐Eurasia collision.

Final closure of the Paleo Asian Ocean basin in the early Triassic

open access: yesCommunications Earth & Environment, 2022
The suturing of the southern Altaids and final closure of the Paleo Asian Ocean within Pangea occurred during the early Triassic, according to geochemical and detrital zircon provenance analyses of sandstones in the Muzitekexie fore-arc accretionary ...

Tectono-magmatic evolution of the Philippine Sea Plate: A review

open access: yesGeosystems and Geoenvironment, 2022
The West Pacific Margin incorporates 75% of global marginal basins/back-arc basins. These basins and their adjacent trenches and island arcs constitute a huge trench-arc-basin system created by the interactions among three tectonic plates (the Pacific ...

Temporal and spatial distribution of the Qom Formation pyroclastic deposits with special emphasis on SE Kerman Province: Their application in (tephra) event stratigraphy [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2022
This article is the first published example of the application of (tephra) event stratigraphy in the Qom Formation as well as the temporal and spatial distribution of the Qom Formation pyroclastic deposits. The presence of igneous (volcanic) associations

Discovery of Ancient Volcanoes in the Okhotsk Sea (Russia): New Constraints on the Opening History of the Kurile Back Arc Basin

open access: yesGeosciences, 2020
Here we present the first radiometric age and geochemical (major and trace element and isotope) data for samples from the Hydrographer Ridge, a back arc volcano of the Kurile Island Arc, and a newly discovered chain of volcanoes (“Sonne Volcanoes”) on ...

Sequence stratigraphy of the Qom Formation in the Sirjan–Abadeh region [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2021
Sequence stratigraphy of the Qom Formation deposits (in two stratigraphic sections) in the Sirjan–Abadeh region has been studied. This formation in the Sirjan area (Bujan section; with Rupelian–Chattian age and 156 m thickness), consists mainly of medium-
