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
Egypt

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.

All about Turbidite and Porphyry Properties
Know all about Turbidite and Porphyry properties here. All properties of rocks are important as they define the type of rock and its application. Turbidite belongs to Sedimentary Rocks while Porphyry belongs to Igneous Rocks.Texture of Turbidite is Mud-rich, Sandy whereas that of Porphyry is Porphyritic. Turbidite appears Dull and Banded and Porphyry appears Dull. The luster of Turbidite is metallic while that of Porphyry is dull. 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. The commercial uses of Turbidite are cemetery markers, creating artwork and that of Porphyry are creating artwork, gemstone, jewelry.
