"Majorite" and "silicate perovskite" mineral compositions in xenoliths from Malaita.
Mineral Compositions in Xenoliths from Malaita The report by Collerson et al. (1) of transition zone and lower mantle phases in mantle-derived material from alnöite pipes on Malaita, Solomon Islands, is highly significant in view of the rarity of such natural assemblages. Malaita is part of the obducted southern margin of the Ontong Java Plateau, an area of overthickened oceanic crust (2–7) tha...
متن کاملTEM OBSERVATIONS OF AMORPHIZED SILICATE-PEROVSKITE, AKIMOTOITE AND Ca-RICH MAJORITE IN A SHOCK-INDUCED MELT VEIN IN THE TENHAM L6 CHONDRITE
Introduction: Tenham is a famous highly shocked L6 chondrite. Previous studies revealed a series of high-pressure minerals in the melt vein, including ringwoodite, majorite, wadsleyite, magnesiowüstite, akimotoite, silicate-perovskite, and hollanditestructured plagioclase [1-8]. These high-pressure minerals have been studied intensively in static highpressure experiments [9,10]. The presence of...
متن کاملHow much heat and REE in calcium silicate perovskite?
A number of geochemical arguments suggest the existence of a deep mantle reservoir enriched in noble gases and heat producing elements and having a subchondritic Nd/Nd ratio [1-4]. To test this hypothesis, the affinity of these elements for the phases involved in the differentiation of the deep mantle must be determined. Partitioning data between Mgand Ca-silicate perovskites and silicate melts...
متن کاملComputer Simulations of Iron in Magnesium Silicate Perovskite
We use atomistic computer simulation techniques to investigate the site partitioning of iron in (Mg,Fe)SiO 3 perovskites. Our calculations predict that the most energetically favourable reaction for iron substitution will be a direct exchange ofFe 2+ for Mg 2+. Substitution f Fe into the octahedral site and Si into the 8-12 fold coordinated site, as proposed by Jackson et al. [1987], is predict...
