Underground Biomes Stone Types and Statistics

The mod adds 24 stone types, each with its own physical properties. Igneous rocks are generally the hardest to mine, while Sedimentary rocks are the softest and often contain unique resources like fossils.

Igneous Rocks

Formed from solidified magma, these are the toughest stones in the mod.

Metamorphic Rocks

Rocks transformed by heat and pressure. They often appear in striking colors.

Sedimentary Rocks

Formed from compressed layers of sediment. These stones do not produce cobblestone when broken; they either drop themselves or specific items.
