Question

why are metallic minerals found in igneous rocks​

Answer 1

Answer:

The development of metallic ores in intrusive rocks, such as porphyry copper deposits, is related to the partial melting and rising of crustal material along subduction zones. Metal in these systems may also be contributed from sea‐floor deposits that were subducted and became part of the new magma.
