They are also classified as petrologic type 3, indicating an abundance of chondrules, minimal alteration, and distinct mineral features such as monoclinic low-Ca pyroxene grains with twinning. This classification represents a subtype within type 3 chondrites, signifying a certain degree of metamorphism and mineral composition.
