Editing v0.31 Talk:Volcano

:Which, y'know, kinda makes sense based on the geological processes behind volcanoes and sedimentary rocks.  That is, volcanoes form igneous rock around them, bringing the temperature and pressure up on the surrounding rock and converting it to metamorphic.  So the presence of a brook would indicate that the volcano is dormant enough for water flows to create channels in the area, and also dormant enough that sedimentary rock (and not just plain sediment, or soil) could form and continue to exist.  Just to be clear:  when you say "on an embark tile with a volcano", you ARE talking about a 1x1 region on the Local map of the Embark screen?  And not the 4x4 region which is the usual embark site? --[[User:DeMatt|DeMatt]] 07:03, 27 June 2010 (UTC)

::Aside from that, in my pseudo smartguy terms, volcanoes are upwellings of "new" rock, and are as geologically different from ancient coal-bearing rock (coal is a '''fossil fuel''' y'know) as you can possibly have on the same planet.  Although in the current version, if the embark screen does not list sedimentary rock as one of the layers for the selected biome, you aren't going to find it anywhere in the map no matter how large it is.  I get the impression this is more a game mechanic thing to balance the relative advantages of playing in a volcano area (huge amounts of high value ores and obsidian, easy access to magma with low/no risk).[[User:FleshForge|FleshForge]] 01:42, 7 August 2010 (UTC)

It appears to be simply simple impossible to get coal on a volcano map regardless of what rock layers are shown on the embark screen.  On the other hand, you can make charcoal from burning wood, so the easy access to magma is still a pretty great advantage and you can still make steel eventually.[[User:FleshForge|FleshForge]] 07:00, 14 August 2010 (UTC)
