Shock metamorphism of ordinary chondrites
WebIdentification of astronomical dust composition rests on comparison of Infrared (IR) spectra with standard laboratory spectra; frequently, however, a single mineralogical composition is assumed for spectral matching. Web10 Apr 2024 · The stability of the remanent magnetization in ordinary chondrites is a function of the amt. of the cloudy zones of the zoned taenite grains rather than the bulk amt. of tetrataenite. The Fe-Ni phase diagram indicates that precursor of tetrataenite is paramagnetic when the metamorphic temp. was above 350-400 °C.

WebAll the presolar grains are susceptible, to varying degrees, to destruction by the aqueous alteration and/or thermal metamorphism that lithified the chondrites. Nanodiamonds are arguably the most robust and, possibly, the most abundant type of presolar grain – their abundance is ∼ similar-to \sim ∼ 1400 ppm in chondrite matrices. Webmantle peridotites.
