Ion microprobe U-Pb dating of phosphates in Chelyabinsk meteorite
On February 15,2013, a meteorite fell into the area of Chelyabinsk in Russia .The petrology, mineralogy and geochemistry suggests that the Chelyabinsk meteorite is unambiguously classified into LL5 ordinary chondrite with an intensive shock metamorphism (Galimov et.al 2013). For understanding the thermal and/or impact history of the parent body of Chelyabinsk meteorite, we have performed the ion microprobe U-Pb dating of the phosphates in Chelyabinsk meteorite, which are the host-mineral of U in the ordinary chondrite.
