The lack of fragments along the veins suggests no shearing movement happened, and the small number of weak shock signatures points to S2 level, and the oriented pressure in the parent body might come from burial induced pressure. The meteorite might came from a location in the CV-CK parent body where melting, and weak impact related fracturing and vein filling happened. In this an environment alteration of the primitive material started, possibly from a zone transitional between the shallow, less processed CV, and the deeper, more processed CK chondrites.
