HAH 237 is = formally classified as being a CH (petrologic type 3) chondrite and S3, = W2. However, I've seen it listed on many websites as a CH-BEN (Metal = rich Bencubbinite). I thought that CB or Bencubbinites are now a = separate classification including the 5 members: Bencubbin=20 Gujba NWA 1814 QUE 94411 Weatherford So what am I missing? Is it just a general lag or reluctance in taking = up a new Carbonaceous group? Or do I have it completely wrong and this = meteorite is somehow different. Would appreciate any answers with this = one!
