| Abstract: | In this paper, physical properties, chemical compositions and microstructural characters of cosmic dusts from different strata in some areas at China are dis-cussed, and contrasted with magnetic spherules from various oceans. It is believed that these cosmic dusts are of extraterrestrial origin. It might be the droplets sprayed from the fusion crust of a meteorite as it is ablated by grazing in atmo-sphere . |
