    Sammanfattning : This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigation are compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromite grains ( >63 ƒÊm ) per kilogram limestone were found.
