Hello, I have putted on my website three specimens (mirror polished) of my JAH 626 (in fact found by my lucky girlfriend, her second meteorite found !)... Classified by Tony Irving, this meteorite is realy highly shocked and melted :
"The level of shock experienced by this specimen was equal to that in some Martian meteorites, based on the features in plagioclase ! " Polymict breccia composed of both basaltic eucrite and cumulate eucrite clasts plus related debris. Pigeonite of various compositions (some exhibiting exsolution lamellae of clinopyroxene within orthopyroxene), calcic plagioclase, silica polymorph, chromite, troilite and rare zircon. Low-Ca pigeonite (Fs32.1-39.3Wo6.3-5.1; FeO/MnO = 29.5-31.2), clinopyroxene exsolution lamellae (Fs30.6-33.5Wo31.9-29.8; FeO/MnO = 30.7-31.0), pigeonite (Fs51.8Wo12.7; FeO/MnO = 30.8). Plagioclase has been transformed by shock into aggregates of fine anisotropic blades in a subspherulitic texture, indicative of quenching from melt. http://www.wwmeteorites.com/JAH626.html Regards, Fabien Fabien Kuntz Météorites (ventes, expertise, conférences) Animation scientifique et technique WWMETEORITES (Siret : 511 850 612 00017) www.wwmeteorites.com ______________________________________________ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
