Regional Ore Distribution & Cave Ecosystems

!GeoCaves. Ore, geode and caves update

GeoCaves is a vanilla Minecraft datapack that completely rewrites underground ore generation, adds biome‑specific cave vegetation, decorative stone layers, custom geodes, and TNT veins. Now every biome group has its own set of ores, cave plants, and hidden surprises – making mining a regional adventure.

Regional Ores

All vanilla ore entries are removed. Each biome group receives a fixed set of ores at specific heights (upper layer: y ≤ 32, lower layer: y ≤ -32). The table below shows the ores for each region and the list of biomes they cover.

Compass – Always Know What to Mine

When holding a compass in either hand, an actionbar message appears showing the ores available in your current region. It updates once per second (20 ticks) to reduce performance impact.

There is also a convenient advancement system that tells you which ores belong to which region. To unlock an entry, simply visit the region and go underground.

New Geodes!

Amethyst geodes are now exclusive to the Magical region. In their place, we’ve added several new geodes with unique contents – and they appear not only in the Overworld, but also in the Nether and the End!

Geode Type	Where to Find	Special Contents
Diamond	Mountain & Snowy biomes	Diamond ore, air‑filled
Emerald	Calm biomes	Emerald ore, slime blocks, froglight
Lapis	Aquatic biomes	Lapis ore, prismarine, sea lanterns
Amethyst	Magical biomes	Amethyst blocks, calcite, buds (tiny & giant variants)
End	Small End Islands	Raw iron/gold/copper blocks
Nether Quartz	Nether Wastes	Quartz ore, glowstone
Nether Diamond	Basalt Deltas	Deepslate diamond ore, filled with lava

⚠️ Compatibility & Limitations

❌ Incompatibility with some other datapacks

GeoCaves completely overrides every vanilla overworld biome, as well as basalt deltas, nether wastes, and small end islands. This means it is incompatible with any other datapack that modifies biome JSON files (e.g., global ore rebalancing, world generation overhauls, etc.). Only one such datapack can be active at a time.

❌ Modded biomes

GeoCaves does not affect biomes added by mods or other datapacks. Those biomes will retain vanilla ore distribution, which breaks the regional balance.

Roadmap

• English translation
• NeoForge and Fabric versions with more compatibility
• Backport to Minecraft 1.21.5
