User blog comment:Unownshipper/Metallurgists Wanted: Rapture's Natural Resources/@comment-24819226-20140810131157

Actually, we need a geologist rather than a  metallurgist. :)

Couple of things, while the soil around volcano's is VERY good for growing, that is the case after proccesses on the surface have been working on it a while. I am not sure those some proccesses occure in deep water though. So "volcanic soil" made need to be proccessed by Rapture before it can be used as soil for growing. It should be able to be done though.

As for metals? Rapture is screwed IMO. Most of the most important metals are found in sedimentary rock. Rapture being in the region of the Mid Atlantic ridge means that the nearby rock is (geologicaly) new. (It's an expansion zone) Now Rapture could find a natural "Iron Plume" but I doubt it would be easy to get large amounts of iron (or any other desolved metal) out of it on a large scale. (Note the only iron plume I found a reference for is in the South Atlantic) sm
