Autor: E. Zinngrebe, K. Andreev, P. Put, A. Laurent, M. Boursin, Sido Sinnema

Publikováno v: Journal of the European Ceramic Society. 34:523-531

Furnace linings of magnesia-carbon and micro-porous carbon bricks experience cyclic compressive loads. An experimental programme has been carried out to assess the sensitivity of these materials to compressive fatigue failure. Next to room temperatur

Experimental investigations of Si isotope fractionation between Si-bearing metal alloy and silicate phases have to date been limited to high pressure (1–7 GPa) and high temperature (1800–2200 °C) conditions at highly reducing conditions, to opti

A new model for Sb deposition in the French Massif Central based upon thermodynamic modeling of the mineralizing fluid

Autor: C.J. de Wijs, E. Zinngrebe, V.J. Van Hinsberg, Simon P. Vriend

A new model for antimony (Sb) deposits in the Haut-Allier area of the French Massif Central is proposed, based on thermodynamic modeling of the mineralizing fluid. The Sb deposits in the research area contain stibnite and berthierite as Sb minerals,

The largest differentiation event in Earth and other terrestrial planets was the high-pressure, high-temperature process of metal core segregation from a silicate mantle. The abundant element silicon (Si) can be partially sequestered into the metalli

Precambrian and Early Paleozoic evolution of the Andean basement at Belen (northern Chile) and Cerro Uyarani (western Bolivia Altiplano)

Autor: Hans-Gerhard Wilke, R Rössling, Judith Lezaun, E Zinngrebe, A. Beck, Gerhard Wörner, F Lucassen, V. Heber

Publikováno v: Journal of South American Earth Sciences. 13:717-737

Exposures of metamorphic basement in the Central Andes are scarce and reconstructions of the history of the Pacific margin of Gondwanaland must rely on a few isolated outcrops. We studied two areas of exposed basement in northernmost Chile (Belen) an

Metasomatism in mantle xenoliths from Gees, West Eifel, Germany: evidence for the genesis of calc-alkaline glasses and metasomatic Ca-enrichment

Autor: Stephen F. Foley, E. Zinngrebe

Publikováno v: Contributions to Mineralogy and Petrology. 122:79-96

We have investigated new samples from the Gees mantle xenolith suite (West Eifel), for which metasomatism by carbonatite melt has been suggested. The major metasomatic change is transformation of harzburgites into phlogopite-rich wehrlites. Silicate

A Model for Eclogite-Peridotite Interactions: Activity-Driven Metasomatism, with Evidence from the Zero Eclogite Suite, South Africa

Autor: E. Zinngrebe

Publikováno v: Mineralogical Magazine. :1705-1706

It is well known that the dehydration and melting of basaltic oceanic crust in subduction zones is of crucial importance for the geochemical signature of magmatic-arc. At the same time, deep-seated kimberIite-borne eclogite xenolith suites both of So

Metasomatism in Two Natural Peridotites: Effects of Low-aSiO2 Melts

Autor: E. Zinngrebe

Publikováno v: Mineralogical Magazine. :1006-1007

Metasomatism of upper mantle peridotites is a crucial process in the genesis and evolution of magmas in the mantle, yet the knowledge about actual metasomatic agents and processes during metasomatism is still imperfect. No clarity exists about chemic
