RE: [meteorite-list] Achondritic inclusions
Bernd, Could you send me a copy of that JPEG as well? I have some of Dean's unclassified material, most probably NWA 869, and I too have gray, featureless areas in several of mine.

Hello Phil and List, Let me first of all say that your slice is a wonderful example of the many different looks NWA 869 specimens surprise us with! The lower part of your slice looks very much like L3.x or LL3.x material (no surprise as we all know that even L3.8 has been proposed for some NWA 869 lithologies). Those large mineralic clasts look like pyroxene or (especially the one on the right) like a mixture of pyroxene and olivine to me. The possibly achondritic material I was talking about in my post about a year ago, can be seen in O.R. Norton's ENCYCLOPEDIA, p. 144 (lower picture). This fine-grained material - so fine-grained that it remains featureless even under the microscope - is, according to O.R. Norton (p. 144), typical of basaltic achondrites. I am going to send you, Christian, and Maria, (the 869 fan club :-) a JPEG of such an inclusion in one of my NWA 869 specimens (purchased from Dean Bessey) in a private mail so you get a first-hand impression of what I was talking about. It is the gray, featureless area in the 9 o'clock position of the 30.8-gram piece on the left.

Re: [meteorite-list] Achondritic inclusions
ello I have a little to add too :-) In my big NWA869 there are some of the mysterious grey areas that contain metal grains and some that do not. Those witch contain metal grains seems to do that in the exact same way as the rest of the meteorite. In one clast there is a funny one... It looks like an armoured chondruls that has been cut in half and the two half's has been misplaced by a half centimetre, and more, it looks like the chondrule that was once there, is missing, and just leaving the armoured border ??? Metal grains in achondrittic material..no ???

RE: [meteorite-list] Achondritic inclusions
Hi Bernd and Maria and good morning list, I have a slice of Maria's NWA 869 and would like to compare mine to the ones you are talking about. Bernd would you be so kind to send me a copy too? Danke! And Maria, I tried to look at this URL and can't access your image. http://photos.yahoo.com/dragonsoup_maria.
