An ore vein is a rare terrain feature that consists of a long streak of ore and rock.

Structure

An ore vein consists of large, long, streaking collections of ore and a filler rock material. At and above Y=0, ore veins consist of copper ore mixed with granite. Below Y=0, veins consist of iron ore mixed with tuff. They can also contain raw metal blocks.

Generation

Ore veins are rare and huge, containing a large quantity of ore blocks.[more information needed]
