Find 2002

Eucrite polymict Nuevo-laredo group 



History: Meteorite stones scattered in an area of 4 km2, were found in the desert of Oman. 
Several additional pieces were collected 1 km SW of the main strewn field in February 2002.

Physical characteristics: The total weight of 27 pieces is 651 g. The stones are dark green without fusion crust.  

Petrography: (Lorenz C. and Nazarov M., Vernad): The meteorite is a polymict breccia consisting of lithic fragments and mineral clasts, 
embedded into a fine-grained clastic matrix. Melt pockets and glass veins occur in the breccia. The lithic fragments are mostly 
fine- and medium-grained pyroxene-plagioclase rocks of porphyritic, gabbroic, minor poikilitic and granular textures. 
The exsolution texture of inverted pigeonite is disturbed by shock. The pyroxenes show mosaicism. Plagioclase is partially isotropic. 
Minor phases are olivine, ilmenite, spinel, silica calcium phosphate, troilite and FeNi metal. 
Geochemistry: (Kononkova N., Vernad., EMP): major phases: orthopyroxene: En35.6Wo3.3 (Fe/Mn=33); 
clinopyroxene En29.8Wo40.5 (Fe/Mn=33); feldspar An89.2Ab10.4; olivine Fa79.2 (Fe/Mn=48). Spinel is represented by Al-Ti-chromite. 
Bulk chemistry (wt%) (Roshchina I., Vernad., RFA): SiO2 52,48, TiO2 0,690, Al2O3 11,01, Cr2O3 0,19, FeO 18,15, MnO 0,490, 
MgO 5,32, CaO 10,81, Na2O 0,84, K2O 0,113. 
(Lorenz A., Vernad., INAA): ppm La 4.45, Ce 10.0, Nd 5.78, Sm 1.75,  Eu 0.33, Tb 0.44, Yb 1.72, Lu 0.30, 
Sr 415, Ba 640, Sc 31.8, Ni 190, Co 7.34. 
Oxygen isotopes composition (Franchi I., OU): d17O=1.848 ‰  d18O=3.963 ‰. 

Classification: This meteorite is a moderately shocked weathered polymict eucrite that belongs to the Nuevo-Laredo group.

Specimens: A total of 89 g of sample and one thin section are on deposit at Vernadsky Institute. 
An anonymous collector holds the main mass.
