The geotectonic environments of Early Precambrian granulites in Brazil

, 1979
A review is presented concerning Archaean granulites occurring in some old domains of the South American Platform, which was consolidated at the end of the Brazilian Cycle (900-500 Ma).

The Precambrian of Gotland, a key for understanding the Proterozoic evolution in southern Fennoscandia

, 2021
Gotland is an island in the central part of the Baltic Sea, with up to 800 m Palaeozoic sedimentary rocks on top of a Precambrian basement belonging to the East European Craton.

The pre‐Vendian (640–610 ma) granite magmatism in the Central Taimyr fold belt: the final stage of the Neoproterozoic evolution of the Siberian paleocontinent active margin

Геодинамика и тектонофизика, 2019
Eastern part of the Central Taimyr belt is composed of Precambrian rocks penetrated by granites of the Snezhnaya complex (845–825 million years) and later overlain by mid‐Neoproterozoic sin‐ postorogenic sedimentary deposits of the Stanovaya‐Kolosova ...

The Role of Tectonic Inheritance in Active Rift Seismicity and Magmatism: Constraints From 3‐D Gravity Inversion and D‐InSAR Modeling of the 2025 Fentale Swarm, Ethiopia

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The role of inherited lithospheric structures in active rift seismicity and magma intrusion remains a key uncertainty in continental breakup dynamics. We investigate the January 2025 Northern Main Ethiopian Rift swarm using constrained 3‐D gravity inversion and D‐InSAR observations to characterize crustal architecture, seismicity, and active ...

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.

Correlation of the supracrustal complexes of the Small and Large Keivy, North-East of the Baltic Shield

Vestnik MGTU
The issue of correlation between the Small and Large Keivy sections is considered using a technique that includes searching for trends in partially ordered sets of random variables and assessing the degree of similarity/difference between rock ...
