Sources and possible causes of Paleoproterozoic magmatism in the southern part of the Karelian Craton (Baltic Shield)

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018
There is an opinion that Paleoproterozoic magmatism in the Karelian craton of the Baltic Shield is linked solely with the influence of mantle plumes.

Depositional Interplay Between the Ancestral Rocky Mountains and Ouachita–Marathon–Sonora Orogenies: Insights From Provenance Records in the Late Palaeozoic Marfa Basin, West Texas, USA

Basin Research, Volume 38, Issue 2, March/April 2026.
Provenance records from the late Palaeozoic Marfa Basin in West Texas reveal the transition from the Ancestral Rocky Mountains to the Ouachita–Marathon–Sonora orogenies during the early Permian in SW Laurentia. ABSTRACT The Marfa Basin in West Texas is a late Palaeozoic synorogenic depocenter associated with regional deformation linked to the Ancestral

Assessing Inheritance of Zircon and Monazite in Granitic Rocks from the Monashee Complex, Canadian Cordillera [PDF]

, 2007
Zircon and monazite from granitic sheets and dikes in the Monashee complex, Canadian Cordillera, were investigated to determine whether igneous crystallization occurred at 1.9 Ga or 50 Ma with 1.9 Ga inherited zircon and monazite.

A Rare Glimpse of Paleoproterozoic Sub‐Arc Mantle: The Ussuit Peridotite, West Greenland

Geochemistry, Geophysics, Geosystems
Mantle residues beneath Archean cratonic nuclei have been extensively studied, whereas less attention has been given to the mantle lithosphere beneath Proterozoic mobile belts that link these nuclei.

ARCHEAN AND PALEOPROTEROZOIC HISTORY OF ROCK METAMORPHISM IN THE URALS CRUSTAL SEGMENT

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015
In the Urals, Archean and Paleoproterozoic formations were found in several polymetamorphic complexes which crop out as relatively small tectonic blocks (within the first thousands sq. km in area).

Quantifying Multi‐Source Sediment Supply in a Tropical Foreland Basin (Oligocene‐Miocene Nyalau Formation, Borneo)

Basin Research, Volume 38, Issue 2, March/April 2026.
Detrital zircon unmixing identifies three sediment sources for the Oligocene–Miocene Nyalau Formation, including a previously unrecognised syn‐depositional component characterised by Oligocene–Miocene volcanic zircons and Neoproterozoic populations absent from established sources.

Cold deep subduction recorded by remnants of a Paleoproterozoic carbonated slab

Nature Communications, 2018
The onset of modern-style plate tectonics remains under debate. Here, Xu et al. report a cold thermal-gradient recorded in an eclogite xenolith in Paleoproterozoic carbonatite from orogen, and propose that modern-style subduction has operated since at ...

Crustal Evolution of the Himalaya since Paleoproterozoic

, 2022
Understanding the crustal evolution of any orogen is essential in delineating the nomenclature of litho units, stratigraphic growth, tectonic evolution, and, most importantly, deciphering the paleogeography of the Earth. In this context, the Himalayas, one of the youngest continent-continent collisional orogen on the Earth, has played a key role in ...
