Discovery of the Fe-analogue of akimotoite in the shocked Suizhou L6 chondrite
We report the first natural occurrence of the Fe-analogue of akimotoite, ilmenite-structured MgSiO3, a missing phase among the predicted high-pressure polymorphs of Fe-pyroxene, with the composition (Fe2+0.48Mg0.37Ca0.04Na0.04Mn2+0.03Al0.03Cr3+0.01)Σ=1.00Si1.00O3. The new mineral was approved by the International Mineralogical Association (IMA 2016-085) and named hemleyite in honour of Russell ...
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 کاملRingwoodite Microstructures in L-chondrites Rc106 and Acfer040: Implicatoins for Transformation Mechanisms
1. Introduction Ringwooodite, produced by shock metamorphism, is common in and adjacent to melt veins in highly shocked chondrites. Although ringwoodite can crystallize from the silicate melt in the shock-vein or pockets, most of the easily observed ringwoodite in shock veins is formed by the transformation of olivine in host-rock fragments entrained in the melt or olivine along shock-vein marg...
متن کاملRingwoodite Lamellae in Olivine from the L6 S6 Chondrite Tenham: Constraints on the Transformation Mechanism
1. Introduction High-pressure minerals, produced by shock metamorphism, are common in and around melt veins in highly shocked chondrites [1-8]. These minerals either crystallized from silicate melt in the shock-vein or formed by solid-state transformed from host-rock fragments entrained in the melt or along shock-vein margins [3]. The study of these high pressure minerals can give us a better u...
