Iron:Copper:Coal ratio on map

[Qilili]

Is there any data about how these resources are distributed with default settings?

Are they 1 : 1 : 1 ?

Is there any data about how these resources are distributed with default settings?

With default map generation settings, minerals are generated in the approximate ratios:
iron-ore 10
copper-ore 8
coal 8
stone 4
uranium-ore 0.9
(these are from 'base_density' in 'resources.lua')

Great info, exactly what I needed.
