The Hadean origin of the Archean Napier Complex (East Antarctica)

Autor: Martin Guitreau, Mhammed Benbakkar, Abdelmouhcine Gannoun, Maud Boyet, Jean-Louis Paquette, Krzysztof Suchorski, Jean-Marc Hénot, Zoltán Konc

Details regarding the early evolution of the mantle-crust system are still poorly constrained due to the great scarcity of >3.7 Ga rocks in the geological record. The Napier complex (East Antarctica) is an Eoarchean craton that contains some of Earth

Structure and composition of the subcontinental lithospheric mantle beneath the Sangilen Plateau (Tuva, southern Siberia, Russia): Evidence from lamprophyre-hosted spinel peridotite xenoliths

Autor: Claudio Marchesi, Zoltán Konc, Carlos J. Garrido, Victor V. Sharygin, Csaba Szabó, Károly Hidas

Publikováno v: Lithos. :253-263

We present new data on spinel peridotite xenoliths hosted in Agardag alkaline lamprophyres from the Sangilen Plateau (Tuva, South Siberia, Russia), sampling at ~ 450 Ma the subcontinental lithospheric mantle of the Tuva-Mongolian micro-continent that

A camptonite dike swarm (Agardag alkali-basalt complex) in the western part of the Sangilen Upland abounds in mantle xenoliths. Mineralogical, petrographic, and petrochemical studies show that the dikes are composed of lamprophyres of two groups, bas
