Related to the last comment - I'm just now getting around to a new world, and discovered this mod conflicts with 'Dry Mines' (no aquifers). I don't know if adding the CUT tag to each inorganic layer would help, or if a no-aquifers version of the mod is required separately.

An unforeseen consequence of this mod is that it spikes the number of stone types that can be aquifers from three to eight. I've had a couple of embarks in a row with absolutely oppressive aquifers because there's just layer after layer of different sandstones.

Love these logical aesthetic mods. Though I haven't embarked in a desert for awhile, between this and the Giant Scorpion, it may be time.

Thanks for the tip! I updated the mod with switched out tokens.

[IS_SANDSTONE] is not a valid token. You can add [REACTION_CLASS:SANDSTONE] to distinguish these rock types for reactions, but entirely new tokens can't be processed by the game.

Other than that, awesome mod! I hope I can find banded sedimentary layers in one of my embarks someday.
