Writeup from MB 110:

Grove Mountains 050168 (GRV 050168)        72°58’35.8"S, 75°15’55"E

Antarctica

Find: 6 Jan 2006

Classification: Ordinary chondrite (L3)

History: During 2005/2006 field season, 5354 meteorite samples have been selected by CHINARE in Grove Mountains, East Antarctica.

Physical characteristics: This meteorite weighs 7.39 g, has a fusion crust shell and is reddish brown in color.

Petrography: The section shows a closely packed mass of chondrules (0.1-3 mm diameter) and irregular crystalline aggregates with interstitial metal/sulfide and a relatively small amount of matrix. A considerable variety of chondrules is present, many porphyritic chondrules and barred olivine; other types include cryptocrystalline, as well as a few radial olivine chondrules. The mean composition of the olivine and the amount of nickel-iron suggest L group, so the meteorite is classified as L3.

Geochemistry: Olivine Fa17.13±7.86, range Fa4.76-33.16. Pyroxene Fs15.94±6.47, range Fs4.75-22.89.

Specimens: The main mass and one thin section are on deposited at PRIC.
