5 Formation

5.1 Formation

Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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.

Latite vs Porphyry 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 Latite and Porphyry Reserves. Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture. Porphyry is a reddish-brown to purple igneous rock containing large phenocrysts of various minerals embedded in a fine-grained matrix. 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 Latite vs Porphyry information and Latite vs Porphyry characteristics in the upcoming sections.

Latite vs Porphyry 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. Latite vs Porphyry characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Latite and Properties of Porphyry. Learn more about Latite vs Porphyry in the next section. The interior uses of Latite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Porphyry include Decorative aggregates and Interior decoration. Due to some exceptional properties of Latite and Porphyry, they have various applications in construction industry. The uses of Latite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Porphyry include Construction aggregate.

More about Latite and Porphyry

Here you can know more about Latite and Porphyry. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Porphyry consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Porphyry includes Biotite, Chert, Feldspar, Garnet, Graphite, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Latite vs Porphyry, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas, Porphyry is available in black, brown, colourless, green, grey, red, rust, white colors. Appearance of Latite is Rough and that of Porphyry is Dull. Properties of rock is another aspect for Latite vs Porphyry. The hardness of Latite is 5-5.5 and that of Porphyry is 6-7. The types of Latite are Rhomb porphyries whereas types of Porphyry are Rhomb Porphyry. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Latite and Porphyry is white. The specific heat capacity of Latite is 0.92 kJ/Kg K and that of Porphyry is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Latite is heat resistant, pressure resistant whereas Porphyry is heat resistant, impact resistant.
