Definition
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Porphyry is a reddish-brown to purple igneous rock containing large phenocrysts of various minerals embedded in a fine-grained matrix
Origin
European Foreland Basins

Etymology
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939
From Old French porfire, from Italian porfiro and in some cases directly from Latin porphyrites

Formation
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.
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.

Turbidite 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. Turbidite vs Porphyry characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Turbidite and Properties of Porphyry. Learn more about Turbidite vs Porphyry in the next section. The interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Porphyry include Decorative aggregates and Interior decoration. Due to some exceptional properties of Turbidite and Porphyry, they have various applications in construction industry. The uses of Turbidite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement and that of Porphyry include Construction aggregate.
More about Turbidite and Porphyry
Here you can know more about Turbidite and Porphyry. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Porphyry consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand and mineral content of Porphyry includes Biotite, Chert, Feldspar, Garnet, Graphite, Quartz, Silica. You can also check out the list of all . When we have to compare Turbidite vs Porphyry, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas, Porphyry is available in black, brown, colourless, green, grey, red, rust, white colors. Appearance of Turbidite is Dull and Banded and that of Porphyry is Dull. Properties of rock is another aspect for Turbidite vs Porphyry. The hardness of Turbidite is 3 and that of Porphyry is 6-7. The types of Turbidite are Not Available 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 Turbidite and Porphyry is white, greenish white or grey. The specific heat capacity of Turbidite 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.Turbidite is heat resistant whereas Porphyry is heat resistant, impact resistant.
