The Bundelkhand-Aravalli craton is the most important lithotectonic unit in the central and western India where Paleoproterozoic Aravalli Supracrustal sequence has been deposited over an Archaean basement, the latter also known as the Banded Gneiss Complex (BGC). A NE-trending linear metasedimentary sequence, designated as the Jahazpur Belt occurs along the eastern fringe of the Aravalli Superg...

Exhumed fossil subduction zones are archives of the deformation conditions and mechanisms from depths not directly accessible. Microstructural analysis samples exhumed therefrom offers insights into micromechanics processes associated with such as earthquakes, slow aseismic creep. Subducted continental metasediments Tuscan Metamorphic Units Italian Northern Apennines contain a mylonitic foliati...

Abstract Aseismic megathrust slip downdip of the seismogenic zone is accommodated by either steady creep or episodic slow events (SSEs). However, geological conditions defining rheology remain elusive. We examined exhumed subduction mélanges on Kyushu, Japan, which deformed at ∼370–500°C under greenschist to epidote‐amphibolite facies conditions, comparable warm‐slab environments. The recorded ...

The hinterland of the Cenozoic Northern Apennines fold-and-thrust belt exposes metamorphic roots chain, vestiges subduction-related tectono-metamorphic evolution that led to buildup Alpine orogeny in Mediterranean region. Like other peri-Mediterranean belts, Palaeozoic continental basement is still poorly constrained, hampering full understanding their orogenic evolution. We report first compre...

The Austroalpine nappe stack of the Pohorje Mountains (Mts.) in northeastern Slovenia comprises a suite eclogite facies metamorphic rocks that were partially assigned to Eo-Alpine ultrahigh-pressure metamorphism (UHPM). We selected micaschist, which was previously related this metamorphism, for detailed study including chemical zonation garnet and potassic white mica, identification mineral inc...

Two episodes of late Neoarchean-early Paleoproterozoic and garnet-bearing leucogranite, named the Baotou Jining–Liangcheng leucogranite are recognized from Khondalite Belt in North China Craton. Geochemical studies show that has high Al2O3 content FeOT/MgO ratio, with a large variation CaO K2O/Na2O ratio. Additionally, is enriched light rare earth elements ion lithophile depleted Nb, Ta, P, Ti....
