Abstract

The bulk Tsarev L5 ordinary chondrite powdered matter and chemically extracted orthopyroxene powder were studied using X-ray diffraction, magnetization measurement and Mössbauer spectroscopy. The unit cell parameters for orthopyroxene in the bulk material and in the extracted powder were the same. Magnetization data also showed similar behavior. However, X-ray diffraction and Mössbauer spectroscopy revealed residual iron-bearing phases in the extracted powder such as Ca-rich clinopyroxene, chromite and hercynite which were observed in the bulk matter. Additionally, the minor ferrous and ferric components were found in the chemically extracted orthopyroxene powder.
