Eclogite xenoliths from Wajrakarur kimberlites, Southern India [PDF]

open access: yes, 2006
Mineralogical characteristics of eclogite xenoliths from three kimberlite pipes (KL2, P2 and P10) of the Proterozoic Wajrakarur kimberlite field of Southern India have been studied. In a rare sample of enstatite eclogite from the KL2 pipe garnet contains

MESO-NEOPROTEROZOIC GRENVILLE-SVECONORWEGIAN INTRACONTINENTAL OROGEN: HISTORY, TECTONICS, GEODYNAMICS

open access: yesГеодинамика и тектонофизика, 2017
The objective of this paper is to represent the main features inherent to Grenville-Sveconorwegian Orogen (GSNO) and to propose a model of tectonic and geodynamic evolution of this orogen based on the results of research concerning similar Precambrian ...

Petrology and phase equilibria of HP/LT eclogite at Gaoqiao, western Dabie and implications for lawsonite development in continental subduction zones

open access: yesFrontiers in Earth Science, 2023
Lawsonite is of great significance for understanding fluid activity, element migration and crust–mantle interactions in subduction zones. Though studies have predicted lawsonite to be present under the P–T regime during continental subduction, no ...

Exhumation Mechanisms of Eclogite in the Southern Appalachians and Evidence for Post-Cherokee Orogeny Movement [PDF]

open access: yes, 2015
The Bakersville, NC eclogite bodies in the southern Appalachians record peak metamorphic conditions of the Taconic orogeny. These high-pressure rocks are surrounded by amphibolite-facies rocks of the Ashe Metamorphic Suite.

Two Contrasting Exhumation Scenarios of Deeply Subducted Continental Crust in North Pakistan

open access: yesGeochemistry, Geophysics, Geosystems, 2022
In Western Himalayan Syntaxis, the India‐Asia continental collision occurred at ca. 50 Ma, while its uplift history and exhumation mechanism are still in dispute despite decades of studies. A new type of eclogite was found in Naran, located ca.

Garnet Lu-Hf geochronology and P-T path of the Gridino-type eclogite in the Belomorian Province, Russia [PDF]

open access: yes, 2019
Eclogites are commonly seen as markers of subduction and thus their presence in Proterozoic and Archean orogenic provinces is crucial information for determining the initiation of modern plate tectonic.

Partial melting of zoisite eclogite from the Sanddal area, North-East Greenland Caledonides [PDF]

open access: yesEuropean Journal of Mineralogy, 2020
Metamorphic textures and a pressure–temperature (P–T) path of zoisite eclogite are presented to better understand the metamorphic evolution of the North-East Greenland eclogite province and this particular type of eclogite.

New data on the composition of growth medium of fibrous diamonds from the placers of the Western Urals

open access: yesЗаписки Горного института, 2023
This article presents the results of studying microinclusions of fluids/melts in diamonds from the placers of the Krasnovishersky District (western slope of the Middle/Northern Urals), which make it possible to establish the evolution of diamond-forming ...
