Re: [meteorite-list] H2 or L2 CLASS METEORITES

Steve, No. By definition, ordinary chondrites have a petrologic classification of 3 to 6. Sometimes 7 depending on the meteoriticist. Petrologic types 1 and 2 do not occur in ordinary chondrites Richard Norton R.F.S. 2ed pg 185 Richard Norton has much more to say about this in both

Re: [meteorite-list] H2 or L2 CLASS METEORITES

I was thinking about this today and I have not had time to research it. Hello Steve, I hope you can do some research sometime, Steve. As H and L are thought to be two unique and real parent bodies, your question can be stated alternately: Were there any places on the H parent body or the L

Re: [meteorite-list] H2 or L2 CLASS METEORITES

No, and there probably never will be, at least I don't think such a classification would ever be widely accepted. Type 2 is an old convention, and has only ever been applied to carbonaceous chondrites. It originated with Wiik (1956), who divided the carbonaceous chondrites into 3 chemical

Re: [meteorite-list] H2 or L2 CLASS METEORITES

Dear Steve; Check the updated pages in your Meteorites A to Z For new list members, it is quite a useful book to determine classification information. It was authored by our own list members Anne Black and the Jensen brothers! I cherish my signed copy that brings me luck! DF steve arnold
