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 ...

A XANES and EPMA study of Fe3+ in chlorite: Importance of oxychlorite and implications for cation site distribution and thermobarometry

open access: yesAmerican Mineralogist, 2019
Chlorite is a ubiquitous product of metamorphism, alteration of magmatic rocks and hydrothermal processes owing to its large stability field and wide compositional range.

Compressional origin of the Naxos metamorphic core complex, Greece: Structure, petrography, and thermobarometry

open access: yesGSA Bulletin, 2019
The island of Naxos, Greece, has been previously considered to represent a Cordilleran-style metamorphic core complex that formed during Cenozoic extension of the Aegean Sea.

Relation between xenoliths and magnetotelluric (MT) conductors in the Pannonian Basin (PB) - Short review [PDF]

open access: yes, 2014
MT deep soundings in the PB detected Conductive Anomalies (CA) both in the crust and at the Lithosphere Asthenosphere Boundary (LAB) in the upper mantle. The shallow depth of the LAB (60-70 km) correlates well with the high heat flow in the PB.

Crustal growth: Some major problems [PDF]

open access: yes
Fundamental problems with models currently used to explain the genesis and evolution of continental crust were raised. These problems focus around the difficulty of generating the upper continental crust from a lower crustal or mantle protolith without ...
