Minecraft Java Edition · Earth Overworld overhaul

There is more
beneath.

The familiar world above. A new world below.
SUBSTELLAR begins with the Earth underground.

01 / The working column

Depth is a
change of place.

From recognizable surface stone to the quiet of the Core. Each depth has its own ground, caves, and minerals.

Working column
Y=-352 through Y=319
Sea level

World height
Working hypothesis

Illustrations explain the direction. They are not in-game captures. The section is schematic, and only features marked Done below are shipped.

02 / Earth underground

Shallows

The world you know, before the deeper world begins.

Base stone
Vanilla underground

Vanilla ore ranges

Vanilla ranges, unchanged: coal, copper, iron, gold, redstone, lapis, diamond near the old floor, emerald in mountains.

Schematic geological section

03 / Earth underground

Deepwilds

Wide stone. Water. Room to explore.

Base stone
tuff
Biomes
fracture halls · river lowlands · grove

Minerals in this depth

Tin, zinc, silver, sulfur, apatite.

Original generated illustration

A threshold in stone

Light band

A warped stone threshold. The band stays solid, and the ore chart leaves it empty.

04 / Earth underground

Underreach

Still water and a closer kind of ground.

Base stone
dripstone block
Biomes
drip galleries · still lakes · tunnel maze

Minerals in this depth

Lead, nickel, bauxite, fluorite, salt, certus quartz, niter. Certus quartz generates as a mineral in this depth, not as a surface meteor. Salt is a mineral beside the lakes.

A threshold in stone

Dark band

The next descent is earned through stone. Aligned routes stop at the solid band.

05 / Earth underground

Abyss

Tighter passages. A quieter, darker world.

Base stone
polished deepslate
Biomes
close warren · magma vents · quiet vaults

Minerals in this depth

Osmium, uranium, cinnabar.

Original generated illustration

A threshold in stone

Magma band

The stone threshold below the three depths. Heat is localized; there is no lava sea.

06 / Earth underground

Mantle

A narrow crack through immense stone.

Base stone
Basalt
Biomes
basalt seams · cinder pockets · closed foundry

No chart minerals in this depth.

07 / Earth underground

Core

Pale stone. Rare cracks. The deepest quiet.

Base stone
Smooth quartz
Biomes
pale galleries · bright cracks · still heart

Minerals in this depth

Draconium. Only in the smooth quartz. None in the Mantle.

Original generated illustration

The current floor

Bedrock.

Y=-352

The bottom of the working world. Final coordinates remain a hypothesis.

02 / The ground under the look

Built in checkpoints.

The illustrated direction includes terrain still in progress. This status comes from the committed roadmap.

Explore the full roadmap

03 / The planet pays

Minerals follow the depths.

The chart is generated in the Overworld. The bands and Mantle have none. Draconium belongs to the Core; oil remains pockets beside the Underreach lakes.

Mantle + bandsNo chart minerals.
Liquids in the column

Sea water at Y=63, river water in the Deepwilds, lake water in the Underreach, crude oil pockets in the Underreach, lava in the magma-vent pockets, and the thin lava band under Y=-208. Crude oil is pockets beside the Underreach lakes. A bucket can pick it up. Machine fluids, including creosote, biodiesel, and the Mekanism acids and gases, are not world layers.

04 / Current work

Vertical routes.

Connected routes through the three depths, still with solid bands and no lava sea.

Sprint 10.2 on the roadmap
