Stone layers

BACK ← → NEXT

In Underdog, there are layers of stone that generate depending on biomes.

• Igneous Extrusive:
  Andesite, Basalt
  (Top)

• Igneous Intrusive:
  Diorite, Granite, Gabbro
  (Bottom)

• Metamorphic:
  Quartzite, Marble, Slate
  (Middle)

• Sedimentary:
  Dolomite, Limestone, Sandstone
  (Middle)

Stone layers generate in the following way:
Igneous Extrusive 🔹
Any 🔹
Composite Rocks 🔸
Any🔹
Igneous Intrusive 🔹

🔸 Between 60 - 70 blocks, there is always a Composite Rocks layer. That is composed mainly of Quartzite. This layer is also the most unstable and can contain boulders. It generates is all the biomes.

🔹 After the Composite Rocks layer, there are always two other stone layers under and above. That can vary depending on biomes.

Ok, you might think. But where do all the different stones generate, actually?
Well, let me explain there...
