Some important elements in this type of meteorite:
Ordinary chondrite: A major class of chondrites, characterized by sub-solar Mg / Si and refractory / Si ratios, oxygen isotope compositions plotted above the terrestrial fractionation line, and a large volume percentage of chondrules, with only 10-15 vol% fine-grained matrix.
LL group: The chemical group low-iron, low-metal (LL) of common chondrites, characterized by its low siderophilic element content, fairly large chondrules (~ 0.9 mm), and oxygen isotope compositions that are further above the terrestrial fractionation line than those of other common chondrites. .
Type 3: Denotes chondrites that are characterized by abundant chondrules, low degrees of aqueous change and unbalanced mineral deposits. Many of the low-Ca pyroxene grains are monoclinic and show polysynthetic twin. The type 3 chondrites can be divided into subtypes from 3.00 (at least metamorphosed) to 3.9 (almost metamorphosed to type 4 levels). If there is primarily intestinal glass in the chondrules, it belongs to type 3
