1.1 Definition

Rhyodacite is an extrusive volcanic rock intermediate in composition between dacite and rhyolite

During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

5 Formation

5.1 Formation

Rhyodacite 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.

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.

All about Rhyodacite and Suevite Properties

Know all about Rhyodacite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Rhyodacite belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Rhyodacite is Earthy whereas that of Suevite is Earthy. Rhyodacite appears Skeletal and Suevite appears Banded. The luster of Rhyodacite is greasy to dull while that of Suevite is earthy. Rhyodacite is available in black to grey, dark greenish - grey colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Rhyodacite are cemetery markers, creating artwork and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
