Master Thesis title: Classification of chondritic meteorites from Oman using X-ray diffractometry.
Description:During meteorite research campaigns in Oman many so-called „ordinary chondrites“ have been found. Traditionally, classification of these meteorites is performed by a combination of optical microscopy and electron microprobe analysis of petrographic thin sections. With this project a classification based on powder X-ray diffractometry data yielding iron content of silicates and absolute abundances of main mineral phases (pyroxenes, olivine, plagioclase, iron sulfide) is attempted with the goal to provide a means to speed up the classification of large numbers of chondrite meteorites and to determine paired specimens. Previously classified meteorites will be used as a reference, and the study will also include the use of the standard classification method with thin sections. Option for participation in a field campaign in Oman with all steps of meteorite field research.
