I'm the author of the original Realistic Ores.
I found out about this mod now, as I was updating my mod for Factorio 2.1. (Btw, the texture of stromatolites in 2.1 changes so you have some work.)
This is a nice continuation of my concept. More or less how I would do this, maybe a little too gray. (I was basing my texture on the most colorful type of real-life ore that I could find.)
Anyway, I like it. I've added a link to this mod into the description of mine.
