Template:Distinguish Template:Infobox structure An ore vein is a rare underground Minecraft:terrain feature that provides massive amounts of Minecraft:ore. It has a chance to be either an iron or copper based vein. Depending on the ore it is, it will rarely spawn a few raw blocks of that ore. Template:Relevant tutorial
Structure
Ore veins occur as large branching networks of a filler rock, paired with high concentrations of an associated ore type. Copper veins generate between Y=0 and Y=50 and contain Minecraft:copper ore and raw copper, with Minecraft:granite as the filler material. Iron veins generate below Y=-8 and can reach as deep as Y=-60, and contain Minecraft:iron ore and raw iron, with Minecraft:tuff as the filler material.
Ore veins generate similarly to spaghetti caves and share their shape and scale. They snake and branch, forming large networks and eventually reaching dead ends. Where they intersect caves, the player can easily spot them in the floors, walls, and ceilings. The size of a single vein is virtually unlimited; in some cases, more than 2,000 of a particular ore can be found in a single vein.
Ore veins are a part of cave generation and are not decorators. This means they are overridden by caves, mineshafts or other underground structures. This also means they can generate in Minecraft:The Void biome.
The tuff or granite around an ore vein can be replaced by gravel, but the main mineral blocks (iron ore and copper ore) remain. So there can be ore blocks completely surrounded by gravel.
Generation
Ore veins generate the same way as noise caves, in particular spaghetti caves. They are thickest between Y=20 and Y=30 for copper veins and between Y=-40 and Y=-28 for iron veins, and taper off towards the limits of their generation at Y=0 to Y=50 and Y=-60 to Y=-8 respectively. 70% of the blocks within the vein are not changed. Of the remaining 30% between 10% and 30% is the ore material within the vein, with the rest being filler material. 98% of the non-filler blocks generate as normal ore blocks, while 2% are generated as raw ore blocks (Minecraft:block of raw copper and Minecraft:block of raw iron, respectively).
While the composition of veins is Template:W, datapacks may change the shape and size of veins by changing the vein_toggle, vein_ridged and vein_gap density functions supplied to the Minecraft:noise router.
