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! **
|
|
|
|
* git clone git://repo.or.cz/rocks.git ([show](http://repo.or.cz/rocks.git/))
|
|
* (old) Git clone: [https](https://gitorious.org/mt/rocks.git)
|
|
* Forum [post](https://forum.minetest.net/viewtopic.php?f=9&t=11779)

|
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](https://github.com/paramat/biomesdev) and adding
|
|
"rocks?" to depends.txt file inside the biomesdev folder. This is needed,
|
|
becouse "rocks" overrides the standard biome registration callback to patch
|
|
in it's own sedimentary rocks.

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.
|

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.
|
|
|
|
### Pegmatite veis
|
|
|
|
Spawn only in granite. Are bit larger than skarn veins. Contain minerals
|
|
like skarn and more exotic minerals.
