Etymology
From French trachyandésite, trachy + andésite andesite, a lava intermediate in composition between trachyte and andesite
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Formation
Trachyandesite 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.
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.

All about Trachyandesite and Turbidite Properties
Know all about Trachyandesite and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Trachyandesite belongs to Igneous Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Trachyandesite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Turbidite is Mud-rich, Sandy. Trachyandesite appears Dull and Soft and Turbidite appears Dull and Banded. The luster of Trachyandesite is earthy while that of Turbidite is metallic. Trachyandesite is available in black, brown, light to dark grey colors whereas Turbidite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Trachyandesite are creating artwork, pottery and that of Turbidite are cemetery markers, creating artwork.
