Geological layer generator for [Minetest] "rocks"
Aim of this mod is to replace all generic stone (default:stone) and generate underground layers of different rocks.
Features
- layers of different rocks: sort of working
- ore veins: being added
- extensibility, api: changed million times
** Work in progress! **
This mod nor minetest_game/default do not define meaningful biomes. So if you do not want unlimited grassland I suggest installing the Paramat's biomesdev mod and adding "rocks?" to depends.txt file inside the biomesdev folder. This is needed, becouse "rock" overrides the standard biome registration callback to patch in it's own sedimentary rocks.

Documentation
How the underground is generated: todo.
Mod has been rewritten, so no doc yet.
The sedimentary layer
Is implemented by modifiing MGv7 biomes to use rocks's sedimentary rocks. This means that you need mapgen v7 enabled. I also suggest enabling caves and dungeons, as they are cool.
Soil is normlly 50-70 cm deep in real life, so I made soil (dirt) only 1 block thick. Under this thin layer of dirt an sedimentary layer is located. In RL, there is clay and other stuff.
Currently 2 sedimentary formations exists:
Coal
Large panes of coal spawn directly under grass. But be warned, they are really large and not-so-common. Best strategy is to follow rivers (MGv7 ridges) or randomly walk around and dig 2 block hole to see if coal is there.
Clay
Spawn simillary to coal, but not as large.
The Igenous layer
Default stone is aliased to basalt, but for some reason the alias is not working so please treat stone as basalt until I find way to fix it.
Everything below sedimentary and (unimp) metamorphic layer is of igneous origin. Primary rock is basalt. But about half of basalt is replaced by granite. Some smaller fraction (like 20%) is then replaced by diorite and gabbro. These are the primary rocks, and more should come.
Mineral distribution
Mineral ore is placed only in nodes of correct rock and only if the region for the ore is right. These "mineral biomes" can and do overlap and change every like 100 nodes. Following regions are defined:
| Region | minerals |
|---|---|
| Copper | Chalcopyrite, Malachyte |
| Pb/Zn | Sphalerite, Galena |
| Iron | Magnetite |
Skarn deposits
Are larg-ish (15-20m) blobs of skarn stone. They spawn only in granite and limestone. Copper, Lead, Zinc and Iron ores often enrich the skarn stone. Some deposits may (unimp) contain considerable amounts of Molybenium, Uranium and Wolfram ores.
Concentration of the minerals is quite high, as to regard the player for finding a not-so-common skarn vein.
