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
Oil Shale is a fine-grained sedimentary rock from which oil is extracted

Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.

All about Basaltic Trachyandesite and Oil shale Properties
Know all about Basaltic Trachyandesite and Oil shale 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 Oil shale belongs to Sedimentary Rocks.Texture of Basaltic Trachyandesite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Oil shale is Splintery. Basaltic Trachyandesite appears Dull and Soft and Oil shale appears Muddy. The luster of Basaltic Trachyandesite is not available while that of Oil shale is dull. Basaltic Trachyandesite is available in black, brown, light to dark grey colors whereas Oil shale is available in black, brown, buff, green, grey, red, yellow colors. The commercial uses of Basaltic Trachyandesite and Oil shale are an oil and gas reservoir, commemorative tablets, creating artwork.
