Porphyry is formed in two stages: the magma cools slowly deep within the crust or the magma is cools rapidly as it erupts from a volcano, creating small grains that are usually invisible to naked eye.

All about Porphyry and Tonalite Properties

Know all about Porphyry and Tonalite properties here. All properties of rocks are important as they define the type of rock and its application. Porphyry and Tonalite belong to Igneous Rocks.Texture of Porphyry is Porphyritic whereas that of Tonalite is Phaneritic. Porphyry appears Dull and Tonalite appears Banded and Foilated. The luster of Porphyry is dull while that of Tonalite is subvitreous to dull. Porphyry is available in black, brown, green, grey, red, rust, white colors whereas Tonalite is available in black, brown, light to dark grey, white colors. The commercial uses of Porphyry are creating artwork, gemstone, jewelry and that of Tonalite are cemetery markers, creating artwork.
