Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate
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

All about Limestone and Basaltic Trachyandesite Properties
Know all about Limestone and Basaltic Trachyandesite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Basaltic Trachyandesite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Basaltic Trachyandesite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Limestone appears Rough and Banded and Basaltic Trachyandesite appears Dull and Soft. The luster of Limestone is dull to pearly while that of Basaltic Trachyandesite is .
