Various blobs, in the form of patches of ore, dirt, diorite, granite, and gravel.

A blob[1][2][3] is a terrain feature consisting of a natural deposit of ores or other blocks in the ground.

Generation

Players can come across these blobs in caverns or anywhere where there is natural stone. Underground deposits of dirt and gravel are generated in this step, followed by the more precious ores: coal, iron, gold, redstone, diamond, emerald (in mountains biomes) and lapis lazuli. They can form only in stone, andesite, diorite and granite (also in their polished variants, replacing parts of structures), and do not replace each other or any other block. Note that two or more blobs can form next to each other and make it look like a blob made of more than one material.

The Overworld

This section is missing information about: generation of emerald ore (see here), does this match up with the values provided on the table below?.

The Nether

This section is missing information about: Java Edition patches, do they match Bedrock; 20w21a basalt deltas changes; does soul sand truly generate as a blob? apparently it doesn't show up in the same region of code}.

  1. ↑ can replace the same type block, if the replaced block aren't part of the said blob.
  2. ↑ a b c d This distribution follows its own rules: instead of a minimum and a maximum height, it is based on a center height and a spread value. By default, these values are set to 16 and 16 for Lapis Lazuli and 8 and 16 for Ancient Debris. Meaning that Lapis Lazuli and Ancient Debris generate mostly around level 15; i.e. a periodic gaussian distribution.
  3. ↑ This is the extra rolls for gold ore in badlands biomes.
  4. ↑ a b Ancient Debris can generate in 2 different ways.
