The meteorite crashed on a flat metal roof of a house, went through it and then struck the floor, leaving a depression that was roughly 2 inches in diameter. The high-velocity impact caused the main mass to break into several smaller pieces. The shards\u2019 total recovered mass was <1 kg. The major silicate minerals olivine (Fa29) and low-Ca pyroxene (Fs24) are highly equilibrated and homogenized and petrologically classified as LL type. The brecciated matrix contains a variety of lithic, chondrule and mineral clasts that further resemble a \u2018fragmental breccia\u2019 and are believed to be the remanent of a larger impact that affected the entire LL parent body. The Kopargaon experienced thermal metamorphism, and the peak metamorphic temperature is estimated to be around 727\u00b0C. It was subjected to a low to moderate degree of shock stage S2-3. The post-peak thermal metamorphism includes a cloudy zone in metals (Fe\u2013Ni) formed due to the spinodal decomposition of taenite, which is indicative of slow cooling (preferably below 400\u00b0C). Locally, the presence of shock-melt veins argued for faster cooling during post-shock metamorphism. The mineralogical and chemical characteristics of the meteorite align with those of the stony meteorite samples returned by the Hayabusa mission (JAXA) from the asteroid Itokawa.”<\/p>\n","protected":false},"excerpt":{"rendered":"
