Abstract

A large number of micron sized native iron nuggets (micro iron nugget) occurs in the Triassic-Permian bedded chert Judging from PIXE analyses and microscopic observations, an interstellar origin is deduced. The occurrence of micro iron nuggets is remarkable and is strongly suggestive of the existence of a new accretional mechanism in space.
