Hello Bernd, How can this technically be an 4-5 if there are no chondrules? I could understand sparse but isn't "devoid" a 6 or IMB? I have some 4and 5 grade Chondrules and while some may be weakly outlined they are still present. Or does this mean none actually "none visible to the naked eye?"
Are we looking at another weird chondrite with chondrule voids? Does it appear to be friable/loosely consolidated? Does this matrix resemble any other widespread meteorite that comes to mind?
