Suevite and Porphyry
Definition
Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Porphyry is a reddish-brown to purple igneous rock containing large phenocrysts of various minerals embedded in a fine-grained matrix

Formation
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.
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 Suevite and Porphyry Properties
Know all about Suevite and Porphyry properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Porphyry belongs to Igneous Rocks.Texture of Suevite is Earthy whereas that of Porphyry is Porphyritic. Suevite appears Banded and Porphyry appears Dull. The luster of Suevite is earthy while that of Porphyry is dull. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Porphyry is available in black, brown, colourless, green, grey, red, rust, white colors.
