5 Formation
5.1 Formation
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.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

Porphyry vs Tonalite 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 Tonalite Reserves. Porphyry is a reddish-brown to purple igneous rock containing large phenocrysts of various minerals embedded in a fine-grained matrix. Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture. 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 Tonalite information and Porphyry vs Tonalite characteristics in the upcoming sections.

Porphyry vs Tonalite 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 Tonalite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Porphyry and Properties of Tonalite. Learn more about Porphyry vs Tonalite in the next section. The interior uses of Porphyry include Decorative aggregates and Interior decoration whereas the interior uses of Tonalite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Porphyry and Tonalite, they have various applications in construction industry. The uses of Porphyry in construction industry include Construction aggregate and that of Tonalite include As dimension stone, Cement manufacture, Cobblestones, Construction aggregate, For road aggregate.

More about Porphyry and Tonalite

Here you can know more about Porphyry and Tonalite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Porphyry and Tonalite consists of mineral content and compound content. The mineral content of Porphyry includes Biotite, Chert, Feldspar, Garnet, Graphite, Quartz, Silica and mineral content of Tonalite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Porphyry vs Tonalite, the texture, color and appearance plays an important role in determining the type of rock. Porphyry is available in black, brown, colourless, green, grey, red, rust, white colors whereas, Tonalite is available in black, brown, light to dark grey, white colors. Appearance of Porphyry is Dull and that of Tonalite is Banded and Foilated. Properties of rock is another aspect for Porphyry vs Tonalite. Hardness of Porphyry and Tonalite is 6-7. The types of Porphyry are Rhomb Porphyry whereas types of Tonalite are Dacite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Porphyry is white while that of Tonalite is bluish black. The specific heat capacity of Porphyry is Not Available and that of Tonalite is 0.92 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 Tonalite is heat resistant, pressure resistant, water resistant.
