Is quartz feldspar porphyry metamorphic

No, quartz feldspar porphyry is not a metamorphic rock; it is an igneous rock. It forms from the slow crystallization of magma beneath the Earth's surface, leading to larger crystals of quartz and feldspar embedded in a finer-grained matrix. Metamorphic rocks, on the other hand, are formed from the alteration of existing rocks due to heat, pressure, or chemically active fluids.
