Maybe the triboelectric charging is responsible for laminated flow, seen for example at the Mt St Helens eruption.
A laminated flow in space could produce the stratified comets and asteroids. Or the laminated flow produced the rocks on Earth and they got blasted intact into space.
If a laminated flow is produced by triboelectric charging instead of gravity sorting, then the number of layers in such a flow could be huge. Thus the geological column could more easily be produced by just a few events.
