mediumOreRock:0 is Barite, which is very much not a Carbonate-class ore.

Unless of course I'm mistaken on the block ID. I very well could be, but that's what shows up when I go in-game.

You may be much more of a geologist than me, but just quoting Wikipedia: "Baryte commonly occurs in lead-zinc veins in limestones".

Ah, I misunderstood your intent here. Carbonate minerals contain the carbonate ion (Barite does not - I actually made a mistake earlier with my list of carbonate minerals, I was looking at another list at the time and got confused). Not a big deal, just a little confusing.

Closing since the generation still works properly, it's just a semantics difference.
