This meteorite is a breccia, a conglomerate of two kind of chondritic rock from the same parent body / astéroid. Lighter to white angular clasts are L6 chondrite type (metamorphosed), that was broken during a major impact event, and embedded in a matrix of more primitive L4 matrix (containing primitive "chondrules").
