GeoStrata is a small mod to diversify underground world generation, making mining and caves more interesting, while simultaneously adding many aesthetic and functional building materials.
Its basic premise is that it adds a bunch of real-world rock types which overwrite 10-20% of vanilla stone. These rocks generate at realistic depths, and in realistic biomes (for example, shale and limestone, being silt/mud rocks, spawn more often in oceans, and cannot spawn in deserts).
GeoStrata cobble can be used as vanilla cobble for use in properly-coded recipes.
