Writeup from MB 103:
Jinju 35°16.8’N, 128°7.4E Gyeongsangnam-do, South Korea Fell: 2014 Mar 9 Classification: Ordinary chondrite (H5) History: A fireball was observed in many places in Korea on 2014 Mar 9, 20:04 (local time) and recorded by numerous car-dashboard cameras. The fireball traveled more than 100 km and disappeared above Gyeonsangnam-do, Jinju area. Many people heard the sonic boom. The next morning a farmer in Jinju found a 9 kg stone at the bottom of his paprika farm (plastic greenhouse). The stone made a hole in the roof of the greenhouse. The second (4.1 kg), third (0.4 kg) and fourth (20.5 kg) stones were found in next few days within 5 km of the first meteorite, bringing the total recovered mass to 34 kg. The stones were brought to either Seoul-NU or KOPRI, in which they were examined and confirmed as chondrites by Byeon-Gak Choi (Seoul-NU) and Jong Ik Lee (KOPRI) Physical characteristics: Four stones are almost completely covered with dark-black fusion crust: their interiors are fresh-looking gray with shiny metal. In the third and fourth stones, found after rain in the area, rusty discoloration is visible along or just beneath the fusion crust. Petrography: Four stones are identical in their petrological characteristics. The rocks consist of olivine, orthopyroxene, plagioclase, diopside, Fe-Ni metal, troilite and minor amount of chromite and apatite. Excluding porous space, vol.% of Fe-Ni metal is ~7.6 and troilite ~3.5. No fine-grained matrix minerals exist. Minerals are chemically equilibrated. Chondrule-matrix integration varies: some chondrules are poorly delineated, while there are many chondrules with sharp edges. Average chondrule size is ~0.57 mm in diameter (n = 225). Geochemistry: Olivine Fa18.29±0.17 (n = 24); orthpyroxene Fs16.18±0.19Wo1.34±0.21 (n = 24); plagioclase An12.48±0.57 (n = 12); chromite Fe/Fe+Mg = 0.83, Cr/(Cr+Al) = 0.86 in atomic ratio. Classification: Ordinary chondrite, H5 Specimens: 312 g and a few thin sections are in Seoul-NU and KOPRI as type specimens. | ||||||||||||||||||||||||||||||||||
