These chondrites, part of the LL group, are characterized by their low iron and metal content, fairly large chondrules, and distinctive oxygen isotope compositions. Petrologic type 3 indicates that this chondrite has abundant chondrules, minimal aqueous alteration, and unique mineral properties, including monoclinic low-Ca pyroxene grains with polysynthetic twinning.
