Raman Spectroscopy of Shocked Olivine in the Hungarian L-Chondrite, Mócs

Introduction. The Mócs meteorite is L5-type chondrite, which fell in 1882, Kolozs county. The meteorite major modal composition are: olivine, pyroxene, plagioclase feldspars, and opaque minerals. The meteorite is highly fractured, and shock induced veins are also discernible. The fractures are filled by iron rich material. The sample contains shock-metamorphic effects (especially in olivine), such as weaklymoderately olivine shock mosaicism, and planar fractures (PF’s) as well as planar deformation features (PDF’s) (Fig. 1). Relatively low interference color in plagioclase and reduce one in pyroxene are also observable in this sample. We have investigated a PDF’s enriched olivine grains using Raman spectroscopy, and searching for evidence for the shock-metamorphic effects in the lattice vibrational changes.
