Grove Mountains 051558 (GRV 051558) 72°56’8"S, 75°19’10"E Antarctica Find: 11 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 3.09 g, the edges and corners are obvious, and it is reddish brown in color. Petrography: The section shows a close-packed aggregate of chondrules, ranging up to 3 mm in maximum dimension; a variety of types is present, mainly including porphyritic, barred olivine, and cryptocrystalline. The small amount of matrix is fine-grained and opaque, and contains a few grains of nickel-iron and troilite. Olivine and pyroxene have variable composition. The shock veins are vclearly visible. The texture and variable mineral compositions are those of type 3, and the amount of metal suggests L group, hence the meteorite is tentatively classified L3. Geochemistry: Olivine Fa24.67±2.12, range Fa19.83-30.34. Pyroxene Fs20.24±6.36, range Fs8.28-34.07. Specimens: The main mass and one thin section are on deposited at PRIC. | ||||||||||||||||||||||||||||||||||
