NWA 3329

 

NWA 3329

Found Sahara, 2005

Differenciated Achondrite, Vestan (HEDO)

Diogenite

Specimen is a 0.72g thin slice with shiny crystals

 

 

Formed in different area of the HED parent body, NWA 3329 and NWA 2968 have been mixed as xenoliths in a new matrix (probably mesosideritic host) and have been found in the same strewnfield on Earth. A real diogenite and a real vestan dunite (the first, the only at this time!)

Look at :

From Meteoritical Society :

 

Physical characteristics: Multiple fragments of a single stone weighing 252 g.

Petrography: (A. Irving and S. Kuehner, UWS) Mostly orthopyroxene with interstitial plagioclase, silica polymorph, merrillite, and trace amounts of kamacite and troilite.

Mineral compositions: Orthopyroxene (Fs29.3–29.5Wo2.4–2.5; FeO/MnO = 26.6–28.6), plagioclase (An88.5–90.1Or0.2–0.3).

Classification: Achondrite (diogenite).

Type specimen: A total of 22.5 g is on deposit at Harper, and one polished thin section is on deposit at UWS. Kuntz holds the main mass.

NWA 3329 DIOGENITE灶神星隕石

NWA 3329

 

NWA 3329

Found Sahara, 2005

Differenciated Achondrite, Vestan (HEDO)

Diogenite

Specimen is a 0.24g slice

這是來自于灶神星母體的不同區域  NWA 33299(DIOGENITE) NWA 2968(Dunites)已經融合成一個基質再灶神星上 這是由於兩個不同的隕石衝擊融熔在灶神星母體上的結果

 

這是一個重大的科學發現 但是目前將NWA 3329歸類為(DIOGENITE) 而事實上他與Dunites是有關聯的
