In addition to that...............a HIGH percentage of NWA meteorites come
through Rissani.

>> Hello List, I am bored so I thought I would try something new, a
>> pre-classification (bid) sale! This meteorite is at NAU getting
>> classified
>> as you read this.
>> It has been given the name NWA 2906 and this is the ONLY FULL SLICE in
>> existence so if you like full slices, this is your only chance to have
>> one
>> from this new meteorite. The TKW of NWA 2906 was 194 grams. The rest of
>> this meteorite is in part slices and the main mass. This was purchased in
>> Rissani, Morocco, so unless nwa 869 is from Rissani, they should not be

>> "NWA 2906, L4, regolith breccia with an assortment of clasts
>> (7.6-gram slice from Tom)
>>
>> According to a preliminary analysis by Ted Bunch from NAU, NWA 2906 might

>> assortment of different clasts, chondrules, and chondrule fragments. It
>> is
>> fairly rich in troilite (FeS) and nickel-iron (FeNi) metal, several FeNi

>>
>> barred olivine chondrules (BO), porphyritic olivine pyroxene chondrules
>> (POP), armored chondrules, radiating pyroxene chondrules (RP), and a few
>> polysomatic BO chondrules. While several chondrules still have
>> well-defined
>> rims, others show poorly delineated rims which would be indicative of an
>> L4-5
>> or L5 chondrite.
>>
>> The degree of recrystallization of the matrix would also point to an L5
>> classi-

>> black,
>> glossy melt veinlets. *One totally amorphous, kidney-shaped, grayish

>>
>> *my note, this slice does not have this inclusion.* if you want a part
