Coupling Phase Equilibrium Modelling and Apatite‐in‐Garnet Elastic Barometry to Unravel the P–T Path of the Micaschist Unit From the Zicavo Metamorphic Complex (Corsica, France)

Journal of Metamorphic Geology, Volume 43, Issue 7, Page 681-705, September 2025.
ABSTRACT To gain insights into the pressure–temperature evolution of a scarcely studied portion of the Variscan basement of Corsica in southern Europe, we combined phase equilibrium modelling, Zr‐in‐rutile thermometry and apatite‐in‐garnet elastic barometry. We investigated Grt‐St micaschist rocks containing garnet grains of several millimetres in size

Structure of the NE Oman Mountains: A Review of Robust Geochronological Constraints for Tectonic Models of Ophiolite Obduction and Continental Subduction

Tectonics, Volume 44, Issue 8, August 2025.
Abstract The Late Cretaceous Semail ophiolite, Oman was emplaced onto the previously passive continental margin of Arabia. Recent geochronology from the ophiolite, its metamorphic sole, and associated high‐pressure (HP) metamorphic rocks have resulted in a proliferation of new tectonic models explaining the sequence of events associated with ophiolite ...

The Distribution of Major and Trace Elements Across a Garnet Population From the Kalak Nappe Complex (Finnmark, Scandinavian Caledonides): Evidence for Size‐Dependent Growth and Compositional Equilibration in the Garnet Zone

Journal of Metamorphic Geology, Volume 43, Issue 6, Page 613-640, August 2025.
ABSTRACT A garnet population from the lower Kalak Nappe Complex in Finnmark (Arctic Norway) was characterized using high‐resolution X‐ray micro‐computed tomography, electron probe micro‐analysis and laser ablation inductively coupled plasma mass spectrometry mapping to assess the extent of compositional equilibration and the controlling crystallization

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

Геофизический 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 ...
