Don't like Create's stone variants? Create has a config option to disable all worldgen, but that also disables Zinc Ore. Since Zinc is a crucial component in many contraptions, disabling it locks you out of a big part of the mod's content (assuming you're in survival). This mod only disables Create's stone variants, while keeping the mod playable.
Features:
Prevents Striated Ores (Asurine, Crimsite, Limestone, Ochrum, Scoria, Scorchia and Veridium) from generating in your world. Also disables all their recipes.
