pecuniumSo this website has a news story on bacteria being a possible means of stabilising soil, to prevent liquifaction.
In it is this set of passages, A natural culture of Bacillus pasteurii along with oxygen and other nutrients causes calcium carbonate to form around sand grains, cementing them together. The structure of the soil is not changed; the gaps are simply filled in.
"Starting from a sand pile, you turn it back into sandstone," said Jason DeJong, an assistant professor of civil and environmental engineering at the University of California at Davis.
So, we now now that turning sand into sandstone doesn't involve a change in the structure. I guess the flip side, sandstone to sand; is the same, and I can level Monument Valley, cause hey, it's not a change in structure.
