Writeup from MB 106:
Abbans-Dessous 47°7.905’N, 5°52.533’E Franche-Comté, France Find: 2015 Jul 25 Classification: Ordinary chondrite (LL6) History: On 25 July 2015, while he was looking for fossils in the Franche-Comté region, geologist Quentin Louis discovered a small black stone in the vicinity of Abbans-Dessous village, and recognized it as a possible meteorite. On 3 August 2015, he contacted Fabien Kuntz, a meteorite hunter living nearby in Besançon, who confirmed the stone was a meteorite. Despite several days of hunting together in the area over the summer 2015, and a notice to the local population, no other stones were found. Physical characteristics: A single, fully crusted, roughly cubic stone. Petrography: Microscopic observations on a polished section show a recrystallized chondritic texture with chondrules making most of the volume. Plagioclase to 100 μm. Chromite to 150 μm. The bulk density (bulk volume from X-ray microtomography) is 3.15 g/cm3 in agreement with the average LL value (3.21±0.22, N=39 falls, see Britt and Consolmagno, 2003). Geochemistry: Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.20. Saturation magnetization (measured on the full stone) is 3.74 Am2/kg. Other magnetic properties indicate that a significant fraction of the FeNi metal is tetrataenite. Olivine Fa29.0±0.1 (N=2), Orthopyroxene Fs23.9±0.3 Wo2.0±0.2 (N=2). Classification: LL6. Specimens: Type specimen (including a polished section) at CEREGE. Main mass with the finder Quentin Louis. | ||||||||||||||||||||||||||||||||||||
