Existence, survival and recognition of icy meteorites on Antarctica with respect to palaeotemperatures
On the basis of characteristics of some meteorites (cold meteorites after falling, fragility), of the
chemical condensation model Of the Solar System, and also according to the main components of comets icy
meteorites can be suspected to exist. Firstly, the reasons are listed which make it plausible that icy meteorites can
indeed exist. Secondly, we enumerate arguments for their preservation on Antarctica, where they might be
collected. The survival of an ammonia-bearing icy meteorite implies temperature constraints for Antarctic
palaeotemperatures. An Appendix recapitulate and comment the scientific report on a possible icy meteorite fall in
