Let’s clarify right away: currently, the excavations in the Archeology Update modification are not available – the creator plans to implement this in upcoming versions. At this time, it introduces new blocks to Minecraft.
Features of the Archeology Update Mod
Disclaimer from the creator: everything included in the modification is based on leaked information and rumors from the developers of Minecraft. There is no guarantee that all of this will make it into the game. The creation adds:
Mossy slate – will later be found in a new biome of the game
Ancient remains – similar to vanilla fossils
Marble – a beautiful building block in MCPE
Limestone – is expected to become widely available
Gneiss is produced by heating a granite block.
