This mod changes the blocks generated when lava and water meet. So, when Cobblestone, Stone or Obsidian would be generated, there are chances that other blocks are generated.
By default, only when Stone would be generated there are chances that iron ore, gold ore, redstone ore, lapis ore or diamond ore is generated instead, but this can be sufficiently customized, check out the wiki.
