The extrusive igneous rock equivalent of granite is rhyolite.

Is porphyry granite.

Porphyry is an igneous rock characterized by porphyritic texture. Appearance of granite is veined or pebbled and that of porphyry is dull. 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 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. A granitic rock with a porphyritic texture is known as a granite porphyry. Porphyry is an igneous rock that contains larger crystals phenocrysts in a fine grained groundmass. Porphyry has been used as a paving surface as far back as the roman era.

The groundmass is composed of indistinguishable crystals aphanites as in basalt or easily distinguishable crystals phanerites as in granite. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral. Porphyry copper deposits and read more. Granite is available in black grey orange pink white colors whereas porphyry is available in black brown colourless green grey red rust white colors.

Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. K feldspar phenocrysts in this sample. 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. It forms from the slow crystallization of magma below earth s surface.

Porphyry definition is a rock consisting of feldspar crystals embedded in a compact dark red or purple groundmass. Among the most distinctive hydrothermal deposits is a class known as porphyry copper deposits so called because they are invariably associated with igneous intrusives that are porphyritic meaning the rock is a mixture of coarse and fine mineral grains. The word porphyry comes from the latin word for purple which was the color of nobility to the romans. It s a type of granite that has naturally extruded through the earth s crust.

Porphyritic refers to the texture of the rocks. Porphyry is a diversity of igneous rock consisting of large grained crystal such as quartz and feldspar scattered in a fine grained groundmass. Granitoid is a general descriptive field term for lighter colored coarse grained igneous rocks. Traditional porphyry is a variable thickness stone.

Properties of rock is another aspect for granite vs porphyry.
