A lot of this just makes me think of precipitate. I’m sure there are papers on the Mars environment, I.e. low temperature low pressure geology and physics, but I didn’t immediately see any references. I recall reading another paper indicating there is an unresolved increase and decrease of methane ? in the Martian atmosphere as well. But I’m still inclined to think this is geological not biological.
