1 Geological layer generator for [Minetest] "rocks"
4 Aim of this mod is to replace all generic stone (default:stone) and
5 generate underground layers of different rocks.
10 * layers of different rocks: sort of working
11 * ore veins: being added
12 * extensibility, api: changed million times
14 ** Work in progress! **
16 * git clone git://repo.or.cz/rocks.git ([show](http://repo.or.cz/rocks.git/))
17 * (old) Git clone: [https](https://gitorious.org/mt/rocks.git)
18 * Forum [post](https://forum.minetest.net/viewtopic.php?f=9&t=11779)
20 This mod nor minetest_game/default do not define meaningful biomes.
21 So if you do not want unlimited grassland I suggest installing the
22 [Paramat's biomesdev mod](https://github.com/paramat/biomesdev) and adding
23 "rocks?" to depends.txt file inside the biomesdev folder. This is needed,
24 becouse "rock" overrides the standard biome registration callback to patch
25 in it's own sedimentary rocks.
35 * My Code: GNU General Public License v2 or higher.
36 * Media: see txt files in the texture folder
37 * stated in the corresponding file
42 How the underground is generated: *todo*.
44 Mod has been rewritten, so no doc yet.
49 Is implemented by modifiing MGv7 biomes to use rocks's sedimentary rocks.
50 This means that you need mapgen v7 enabled. I also suggest enabling caves
51 and dungeons, as they are cool.
53 Development notes in [Sed.txt](Sed.txt) file!
55 Soil is normlly 50-70 cm deep in real life, so I made soil (dirt) only 1
56 block thick. Under this thin layer of dirt an sedimentary layer is located.
57 In RL, there is clay and other stuff.
59 Currently 2 sedimentary formations exists:
63 Large panes of coal spawn directly under grass. But be warned, they are
64 really large and not-so-common. Best strategy is to follow rivers (MGv7
65 ridges) or randomly walk around and dig 2 block hole to see if coal is
70 Spawn simillary to coal, but not as large.
75 Default stone is aliased to basalt, but for some reason the alias is not
76 working so please treat stone as basalt until I find way to fix it.
78 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.
79 These are the primary rocks, and more should come.
81 ### Mineral distribution
83 Mineral ore is placed only in nodes of correct rock and only if the region
84 for the ore is right. These "mineral biomes" can and do overlap and change
85 every like 100 nodes. Following regions are defined:
89 | Copper | Chalcopyrite, Malachyte
90 | Pb/Zn | Sphalerite, Galena
95 Are larg-ish (15-20m) blobs of skarn stone. They spawn only in granite and
96 limestone. Copper, Lead, Zinc and Iron ores often enrich the skarn stone.
97 Some deposits may (unimp) contain considerable amounts of Molybenium,
98 Uranium and Wolfram ores.
100 Concentration of the minerals is quite high, as to regard the player for
101 finding a not-so-common skarn vein.
105 Spawn only in granite. Are bit larger than skarn veins. Contain minerals
106 like skarn and more exotic minerals.
