Provenance of Middle Triassic sediments in the Southern Youjiang Basin: Insights from detrital zircon geochronology and tourmaline geochemistry

The Depositional Record, Volume 12, Issue 4, September 2026.
Middle Triassic turbidites in the Youjiang Basin were chiefly derived from a Late Palaeozoic continental arc along the southeastern South China Block, as revealed by detrital zircon U–Pb geochronology and tourmaline geochemistry, supporting a tectonic model driven by Paleo‐Pacific subduction rather than Paleo‐Tethyan closure.

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

The Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.

Crustal Architecture of the Paleo‐Pacific Rift Margin of East Antarctica: Evidence From U‐Pb Ages and O‐Hf Isotope Compositions of Ross Orogen Granitoids

Geochemistry, Geophysics, Geosystems
Granitic batholiths of the ∼500 Ma Ross Orogen in Antarctica are voluminous in scale, reflecting prolific magmatism along the active early Paleozoic convergent margin of Gondwana.

Morphological Changes and Alterations in Erosion–Accretion Patterns in a Semiarid Brazilian River

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Flow regulation by the Castanhão Dam significantly altered discharge dynamics and reduced sediment transport in the Jaguaribe River. Long‐term analysis (1958–2025) reveals attenuated flood peaks, decreased channel migration and progressive downstream stabilisation, highlighting persistent geomorphic adjustments in a regulated semiarid fluvial system ...

Reworking of the Tarim Craton by underplating of mantle plume-derived magmas: Evidence from Neoproterozoic granitoids in the Kuluketage area, NW China

, 2011
Most Neoproterozoic granitoids in the Kuluketage area, northern Tarim Craton are characterized by strongly depleted HREE abundances and high Sr/Y and (La/Yb) N ratios, showing typical geochemical features of adakitic rocks.

The Unique Granite Gorge in Mountainous Adygeya, Russia: Evidence of Big and Complex Geosite Disproportions

Geosciences, 2019
Geological heritage sites (geosites) are subject to conservation and exploitation for science, education, and tourism. Some geosites are big and comprise diverse phenomena.

Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.

Two‐Stage Mafic‐Felsic Magma Interactions and Related Magma Chamber Processes in the Arc Setting: An Example From the Enclave‐Bearing Calc‐Alkaline Plutons, Chinese Altai

Geochemistry, Geophysics, Geosystems, 2021
A systematic data set of petrography, mineralogy, geochronology, and geochemistry is reported for typical arc granitoids and associated mafic microgranular enclaves (MME) from the Chinese Altai, Central Asian Orogenic Belt.
