Rock

The entries on this annotated, structured list of rocks all are items and blocks in Minecraft that: A few fictitious blocks are included in this list; namely, blackstone, deepslate, end stone, glowstone, netherrack, and redstone. Their actual nature is up to the player's imagination.
 * 1) bear a resemblance to real-world rocks,
 * 2) share a name with real-world rocks, or
 * 3) are fictitious but fulfill a similar role to rocks.

The first list here approaches the items as game elements, intended to be useful. The second iteration of this list provides real-world geologic analogies.
