Abundant inclusions/chondrules are present in the dark brown to black matrix. Areas of heavy oxidation exist.","THINSECTIONNUM":"2","THINSECTIONAUTHOR":"Brian Mason","THINSECTIONDESC":"The section shows a close-packed aggregate of chondrules and chondrule fragments, up to 2.4 mm across, in a black matrix which contains a small amount of nickel-iron and troilite. A variety of chondrule types is present, mainly granular and porphyritic olivine and olivine-pyroxene with some radiating and cryptocrystalline pyroxene. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa1-28, mean Fa10 (CV FeO is 76); pyroxene, Fs3-18. The meteorite is classified as an L3 chondrite (estimated L3.3).","OXYGENISOTOPEAUTHOR":"","OXYGENISOTOPEDESC":"","THERMOLUMINISCENCEAUTHOR":"","THERMOLUMINISCENCEDESC":"","ALUMINUMAUTHOR":"","ALUMINUMDESC":"","RECLASSIFICATIONNEWSLETTER":"AMN 44,2","RELCASSIFICATIONNOTES":"Reclassified as an L3.00 Chondrite based on Cr contents of Type II chondrule olivine.\r\nRighter, K., Schutt, J., Lunning, N., Harvey, R., & Karner, J.
