Under such circumstances, the mobilization from Dictyonema shale, transport and redeposition of carbon on and in the fine materials of impact breccias obtain outlines of a very short-term and short-distance process that runs within the highly turbulent impact plume.

For this study, the weighed particles were placed in a tube and wetted with a minimal amount of 70% ethyl alcohol, nominally 10 [micro]L for 1-2 mg PM, and the alcohol was evaporated under vacuum to allow redeposition of any alcohol-soluble species on the particles before adding the cell culture medium.
Recent work including dating of pure secondary uranium phases at Palmottu and another nearby site clearly indicate postglacial mobilization of uranium from primary (mainly uraninite) and secondary uranium phases (uranophane) in open fractures and the rock matrix and redeposition as uranophane after very short travel distances downwards (scale of meters) (Read et al.
