Wangqun's Meteorite Identified by CCTV Identification Group, Maybe Presolar Meteorite Wangqun's Meteorite, a very special meteorite, first identified by CCTV Identification Group, and then confirmed by "Meteoritechina". This unusual meteorite contains corundum Al2O3, spinel Al2MgO4, rutile TiO2, etal. Several minerals detetected belong to presolar grains, so this meteorite has the posibility to be a presolar meteorite. By using isotope analysis to detect the age of the meteorite, we can obtain a clear result if this meteorite is a presolar meteorite or not.
