In which type of magma can I find magnetite? Peraluminous or peralkaline? I've been looking and the peraluminous magma have a lot of oxides so I thought it would be reduced magma so it would have magnetite but I'm not pretty sure.
Probably both but I'd expect to see more in a peraluminous melt. The more mafic the melt the more iron based mineralisation you're going to see.
