Properties of rock is another aspect for granite vs porphyry. Porphyry is an igneous rock that contains larger crystals phenocrysts in a fine grained groundmass. Petrographic examination is required for identification of specific types of granitoids. Porphyry is a diversity of igneous rock consisting of large grained crystal such as quartz and feldspar scattered in a fine grained groundmass.

Porphyry copper deposits and read more. Unlike common granites pophyry has large light colored crystals of quartz or feldspar floating in a red or purple fine grained matrix of smaller crystals. Porphyry is an igneous rock characterized by porphyritic texture. Traditional porphyry is a variable thickness stone.

The romans used it because it had a naturally flat durable surface and the stone was easy to quarry. Hardness of granite and porphyry is 6 7. Porphyry definition is a rock consisting of feldspar crystals embedded in a compact dark red or purple groundmass. It forms from the slow crystallization of magma below earth s surface.

K feldspar phenocrysts in this sample. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. Porphyritic refers to the texture of the rocks.

Porphyry is a textural term for an igneous rock consisting of large grained crystals such as feldspar or quartz dispersed in a fine grained silicate rich generally aphanitic matrix or groundmass the larger crystals are called phenocrysts in its non geologic traditional use the term porphyry refers to the purple red form of this stone valued for its appearance. The groundmass is composed of indistinguishable crystals aphanites as in basalt or easily distinguishable crystals phanerites as in granite. The extrusive igneous rock equivalent of granite is rhyolite. It s a type of granite that has naturally extruded through the earth s crust.

Granite is available in black grey orange pink white colors whereas porphyry is available in black brown colourless green grey red rust white colors.
