I'm more a person who tends to be more mathematical. But I'm interested in this amazing material because it makes me think about life and death itself, almost eschatological (being connected with the aridity and dryness of the desert, which is my mind is the death of rivers and the life around them; the collection or purifying of fossil fuels...)
I've read the sepiolite Wikipedia, and it talks some about the formation, but I would like to know more details about the formation, and particularly the timeline of the formation. If possible (it is not obligatory) with a diagram/drawing explaining the process of formation of sepiolite as time goes on. Feel free to add any further references if you have them.
I add also that I know the article Palaeochannel from Wikipedia that refers information about what is a palaeoriver, if this can be useful for answer my question.
