>>31384176Sorry for the lack of reply. Truth be told, I had been doing my reps since you first asked it, but I admit the subject's not something I know much about. What I can tell you is that the /rrat/ highlands are formed by collisional orogeny due to the two continental plate crashing against each other. Since subduction is rare due to the plates having similar density, the highland is both tall and widespread. It's also probably a hot orogeny like the Himalayas due to its height implying the orogeny has been going on for a while (compared with the Alps for example), which has different implications, but chief among which being that magmatism would be (relatively) more common as the subducted plate is starting to melt, thus creating porphyry copper deposit. I don't know its implications on iron ore quality or even availability, though, so I can't really help you with it. Sorry.
Geologically, a good chunk of /who/ would be a retroarc foreland basin (since the top of the /rrat/ highland belongs to the same plate), where the fold has since been filled up with sediments coming from the eroding highland and/or evaporation of water being trapped in the lowland.
