Fig. 6. CI chondrite-normalized REE, Al and Mg abundance patterns of mesostasis in (a) non-porphyritic chondrules, (b) porphyritic (type I) chondrules, and (c) porphyritic (type II) chondrules from the Allende meteorite. CI chondrite values are from Lodders (2003). REE in mesostasis from all types of chondrules are 10–20 times enriched compared to CI chondrites and are mostly unfractionated.
