Porphyry vs Granite

Porphyry vs Granite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Porphyry and Granite Reserves. Porphyry is a reddish-brown to purple igneous rock containing large phenocrysts of various minerals embedded in a fine-grained matrix. Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Porphyry vs Granite information and Porphyry vs Granite characteristics in the upcoming sections.

Porphyry vs Granite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Porphyry vs Granite characteristics assist us to distinguish and recognize rocks.

Porphyry is available in black, brown, green, grey, red, rust, white colors whereas, Granite is available in black, grey, orange, pink, white colors. Appearance of Porphyry is Dull and that of Granite is Veined or Pebbled. Properties of rock is another aspect for Porphyry vs Granite. Hardness of Porphyry and Granite is 6-7. The types of Porphyry are Rhomb Porphyry whereas types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Porphyry and Granite is white. The specific heat capacity of Porphyry is 0.71 kJ/Kg K and that of Granite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Porphyry is heat resistant, impact resistant whereas Granite is heat resistant, wear resistant.
