Saint-Aubin Meteorite – meteorite ferroso con Distinct Patterns da Francia The Saint-Aubin meteorite is a large meteorite ferroso, discovered in the Saint-Aubin region of Francia. It belongs to the IIIAB class of meteorite ferrosos, which places it among meteorites con a high iron and nickel content. It is estimated to have fallen to Earth approssimativoly 55,000 years ago. Discovery History and Finds The Saint-Aubin meteorite was discovered in 1968 duanello agricultural work, when a farmer encountered a large pezzo of ferrous material. Subsequent excavations led to the discovery of additional fragments. In 2018, modern searches using metal detectors led to the discovery of many more pezzi. Among the largest discovered fragments are pezzi weighing 472 kg and 177 kg.
