Definition
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Origin
-
European Foreland Basins
Discoverer
Unknown
Arnold H. Bouma
Etymology
From its mineral and compound content and its relation with Basalt and Andesite rock
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Archaeological Significance
Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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 Basaltic Trachyandesite and Turbidite Properties
Know all about Basaltic Trachyandesite and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Basaltic Trachyandesite belongs to Igneous Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Basaltic Trachyandesite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Turbidite is Mud-rich, Sandy. Basaltic Trachyandesite appears Dull and Soft and Turbidite appears Dull and Banded. The luster of Basaltic Trachyandesite is while that of Turbidite is metallic. Basaltic Trachyandesite is available in black, brown, light to dark grey colors whereas Turbidite is available in black, brown, green, grey, pink colors. The commercial uses of Basaltic Trachyandesite are an oil and gas reservoir, commemorative tablets, creating artwork and that of Turbidite are cemetery markers, creating artwork.
