Basalt
A hard and heavy rock with some uses in construction. Basalt forms directly from lava erupted volcanically, making it an extrusive igneous rock. The basis of all bedrock in the oceans.
Notes
Basalt is a hard, extrusive igneous rock that forms the basis of ocean bedrock and must be mined using a tier 5 pickaxe. It serves as a versatile industrial ingredient used to produce mortared stone, ashlar, crushed basalt, mill stones, and basic geology research papers. Because each block weighs 7,500 grams and stacks only up to 20, players should plan transport carefully or process the rock near extraction sites to avoid excessive encumbrance.
