 This means that you need mapgen v7 enabled. I also suggest enabling caves 
 and dungeons, as they are cool. 
 
-Development notes in [Sed.txt](Sed.txt) file!

 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:

-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

-there.
