Rock chunk

A rock chunk is any stone chunk, either found throughout the world naturally or spawned with a ~25% chance for each tile of rock mined. Each type of rock will spawn its own chunk, so mining marble will spawn a marble chunk. Each chunk can be cut at the stonecutter's table to yield 20 Stone blocks of the same kind. Rock chunks cannot be sold without first being turned into blocks.

Stone chunks will not be moved automatically, even from a home area, and must be manually designated by the player to be hauled. They can be hauled to any stockpile with the appropriate settings, however dumping stockpile zones default settings include rock chunks.
