The Flux of Meteorites to the Earth: Determinations by Terrestrial Techniques

The flux of meteorites to Antarctica

It is premature to report firm conclusions regarding the past meteorite flux rate from the Antarctic record, as variables related to ice flow, meteorite catchment area, weathering and removal rate are not well constrained. The relative population of meteorite types appears to be broadly compatible with the modern fall population, although there are minor differences. In particular, there are populations of small unusual irons, carbonaceous chondrites and lunar samples not found among the modern falls. In addition, slight compositional differences between modern and old (Antarctic) H chondrites may signal a time-dependent change in the flux to Earth of more common meteorites.
