Abstract
Many microspherules were extracted from the shale of the Permian-Triassic boundary of Wanmo section in the Guizhou province of China. Their number abruptly increased at one place leading to an interesting pattern similar to previous studies. The chemical patterns of these microsperules determined by PIXE analysis were compared with previous results from magnetic components of shale and meteorites. In contention with previous studies illustrating the intrusion of microspherules into the Solar System, it is postulated that the Solar System encountered the giant molecular clouds and the microspherules of the present study came from there.
