Calcium Tschermak’s pyroxene, CaAlAlSiO6, from the Allende and Murray meteorites: EBSD and micro-Raman characterizations
Calcium Tschermak’s pyroxene (CaTs), CaAlAlSiO6, is well known as an important component in pyroxene. It is a member of the Ca clinopyroxene group in which Al dominates in the M1 site. Pyroxenes with more than 80 mol% CaTs were observed previously in Ca-,Al-rich refractory inclusions (CAI) from five carbonaceous chondrites. This study re-investigated the near end-member CaTs in the Allende and ...
متن کاملIntegrating EBSD and magnetic susceptibility data to decipher intensity of SPO and strain in deformed quartzite
Measurement of intensity of shape preferred orientation (SPO) is an important objective of many structural geological investigations. This not only helps in fabric quantification, but also enables in better correlation of the rock fabric with strain and strain-intensity variations that may have implications in regional tectonics. There are several methods available to quantify SPO – e.g. Launea...
متن کاملAllendeite and Hexamolybdenum: Two New Ultra-Refractory Minerals in Allende and Two Missing Links
Introduction: During our nano-mineralogy investigation of the Allende meteorite, we discovered two new minerals that occur as microto nano-crystals in refractory inclusions: Allendeite, Sc4Zr3O12, a new Scand Zr-rich oxide; and hexamolybdenum, (Mo,Ru,Fe), a Mo-dominant alloy. Allendeite, which may be an important ultra-refractory carrier linking Zr-, Scoxides and the more common Sc-, Zr-enriche...

متن کاملEBSD characterization of nano/ultrafine structured Al/Brass composite produced by severe plastic deformation
In the present work, nano/ultrafine structured Al/Brass composite was produced by accumulative roll bonding (ARB) up to eight cycles. The evolution of grain refinement and deformation texture and their effect on the mechanical properties were investigated. It was observed that by increasing the ARB cycles, due to the difference in flow properties of the metal constituents, brass layers necked, ...
