The making of pure quartzose sand in continental interiors: Paraná River (Brazil and Argentina)

Sedimentology, Volume 73, Issue 3, Page 802-837, April 2026.
ABSTRACT As part of a comprehensive project on sedimentary processes in South America, this study focuses on sediment generation in the intracratonic Paraná Basin and monitors the evolution of sand composition along the Paraná River from central Brazil to the Río de la Plata estuary in Argentina.

Exploring the Gravimetric and Geochronological Links in Ancient Terranes of the São Francisco Craton and Borborema Province, NE‐Brazil

Terra Nova, Volume 38, Issue 2, Page 77-86, April 2026.
ABSTRACT Deep crustal fragments and structural lineaments identified through satellite gravity data provide evidence for the extension of the reworked ancient basement of the Central African Block into the northern São Francisco Craton and southern Borborema Province.

Dataset of detrital zircon U–Pb ages and Hf isotopic compositions for the late Paleozoic–Mesozoic strata in the North China block

Geoscience Data Journal
The construction of databases of detrital zircon is important for Earth science research. A total of 27,915 U–Pb ages and 4,968 Hf isotopic compositions of detrital zircons from the upper Paleozoic–Mesozoic strata of the North China Block were compiled ...

Cryogenian Glacial Erosion and Tectonics as Agents of Crustal Recycling

Terra Nova, Volume 38, Issue 2, Page 87-96, April 2026.
ABSTRACT Zircon preserves evidence of recycling processes that link surface environments to the mantle. Combined δ18O‐εHf in zircon fingerprints magmatic sources and tracks how crustal material is reworked over time. We apply statistical analyses to a global compilation that apparently resolves shifts in zircon U–Pb, δ18O, and Lu‐Hf data spanning the ...

New Zealand Geological Timescale 2025

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...

Stages of Carboniferous-Triassic magmatism in the Black Sea region based on isotope-geochronological study of detrital zircons from jurassic coarse clastic strata of the Mountainous Crimea

Геодинамика и тектонофизика, 2020
The article presents the results of U-Pb isotope dating of detrital zircons from the Jurassic coarse rocks in the apex and the western slope of Mnt. Biyuk-Sinor (the southern wall of the Baidar basin, near the village of Orlinoe).

Myanmar and Asia united, Australia left behind long ago [PDF]

, 2016
It is well known that western Myanmar is underlain by a continental fragment, the West Burma Block, but there are arguments about its origin and the time of its arrival in SE Asia.

There were no large volumes of felsic continental crust in the early Earth [PDF]

, 2017
New model growth curves for the continental crust based upon Hf-isotopes in zircon suggest that large volumes of felsic continental crust were present in the Hadean and early Archaean.
