An Analysis of an Appalachian Metamorphic Suite

open access: yes, 2011
The Blue Ridge is one of over a dozen provinces located in the much larger Appalachian Mountain Range which spans across the eastern United States. The Appalachian Mountains began to form close to 500 million years ago and rocks within the Blue Ridge ...

Insights from elastic thermobarometry into exhumation of high-pressure metamorphic rocks from Syros, Greece

open access: yes, 2021
Retrograde metamorphic rocks provide key insights into the pressureerature (P-T) evolution of exhumed material, and resultant P-T constraints have direct implications for the mechanical and thermal conditions of subduction interfaces.

Interaction of mantle convection with the lithosphere and the origin of kimberlites

open access: yesГеофизический журнал, 2013
Thermobarometry of xenolites/xenocrysts from 39 kimberlites of Eurasia, Africa, and North America demonstrates that the deepest xenolites, as well as all the other, are exhumed from the depleted lithosphere implying in agreement with petrologic and ...

Calorimetric thermobarometry of experimentally shocked quartz

open access: yes, 1994
Structural damage in experimentally shock-metamorphosed, granular quartz is quantitatively measurable by differential scanning calorimetry (DSC). Shock-induced loss of crystallinity is witnessed by disappearance of the alpha/beta phase transformation and

The magmatic system beneath the Tristan da Cunha Island: Insights from thermobarometry, melting models and geophysics

open access: yes, 2016
This study provides new insights on the conditions of melt generation and of magma transport and storage beneath Tristan da Cunha Island in the South Atlantic. Situated at the seaward end of the Walvis Ridge-guyot hotspot track, this island is related to

Exhumation of eclogite and blueschist (Cyclades, Greece): Pressure-temperature evolution determined by thermobarometry and garnet equilibrium modelling

open access: yes, 2018
International audienceHigh-pressure rocks such as eclogite and blueschist are metamorphic markers of paleo-subduction zones, and their formation at high-pressure and low-temperature conditions is relatively well understood since it has been the focus of ...
