Eight lines of evidence indicate that the Orosirian Period in mid-Paleoproterozoic time was
characterized by plate tectonics: ophiolites, low T/P metamorphism including eclogites …

Modern-style plate tectonics, often characterised by subduction, is a fundamental dynamic
process for planet Earth. Subduction related eclogites are widely used to indicate initiation of …

When plate tectonics emerged on Earth is one of the most fundamental questions in
geosciences. Nowadays, different arguments from diverse research fields (petrology …

The regime of plate tectonics on early Earth is one of the fundamental problems in Earth
sciences. Precambrian era takes the majority (ca. 88%) of Earth's history and thus plays a …

Abstract The Belomorian Province of the Fennoscandian Shield exposes numerous
Precambrian eclogites, which makes it significant for the study of early tectonic processes …

A model of Mesoarchaean spreading ridge subduction and related metamorphism,
magmatism and deformation in an active continental margin is presented here. The …

Competing evolutionary models and age of eclogite facies metamorphism, Mesoarchaean,
Neoarchaean or Palaeoproterozoic, of the subducted Mesoarchaean oceanic crust (Salma …

The pattern and timing of tectonic discontinuity and partial melting in the Garhwal Himalaya,
resulting from the India–Asia collision, are crucial factors for understanding the evolution of …

The Belomorian Province (BP) of the Fennoscandian Shield is a high-grade belt composed
of Meso-to Neoarchean tonalite–trondhjemite–granodiorite (TTG) gneisses with subordinate …

We investigated the tectonic evolution of amphibolite and blueschist tectonic blocks in the
serpentinite‐or pelite‐matrix mélange, which are distributed at the highest structural level of …
