Porphyry vs Limestone

Porphyry vs Limestone 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 Limestone Reserves. Porphyry is a reddish-brown to purple igneous rock containing large phenocrysts of various minerals embedded in a fine-grained matrix. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. 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 Limestone information and Porphyry vs Limestone characteristics in the upcoming sections.

Porphyry vs Limestone 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 Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Porphyry and Properties of Limestone. Learn more about Porphyry vs Limestone in the next section. The interior uses of Porphyry include Decorative aggregates and Interior decoration whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Porphyry and Limestone, they have various applications in construction industry. The uses of Porphyry in construction industry include Construction aggregate and that of Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.

More about Porphyry and Limestone

Here you can know more about Porphyry and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Porphyry and Limestone consists of mineral content and compound content. The mineral content of Porphyry includes Biotite, Chert, Feldspar, Garnet, Graphite, Quartz, Silica and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Porphyry vs Limestone, 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, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Porphyry is Dull and that of Limestone is Rough and Banded. Properties of rock is another aspect for Porphyry vs Limestone. The hardness of Porphyry is 6-7 and that of Limestone is 3-4. The types of Porphyry are Rhomb Porphyry whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Porphyry and Limestone is white. The specific heat capacity of Porphyry is Not Available and that of Limestone is 0.91 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 Limestone is pressure resistant.
