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
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology
From its mineral and compound content and its relation with Basalt and Andesite rock
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

Archaeological Significance
Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Basaltic Trachyandesite and Conglomerate Properties
Know all about Basaltic Trachyandesite and Conglomerate 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 Conglomerate belongs to Sedimentary Rocks.Texture of Basaltic Trachyandesite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Conglomerate is Clastic. Basaltic Trachyandesite appears Dull and Soft and Conglomerate appears Shiny and Rounded. The luster of Basaltic Trachyandesite is while that of Conglomerate is dull. Basaltic Trachyandesite is available in black, brown, light to dark grey colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Basaltic Trachyandesite are an oil and gas reservoir, commemorative tablets, creating artwork and that of Conglomerate are cemetery markers, in aquifers, tombstones.
