Definition
Trachyandesite is an extrusive igneous rock.
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology
From French trachyandésite, trachy + andésite andesite, a lava intermediate in composition between trachyte and andesite
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Trachyandesite and Conglomerate Properties
Know all about Trachyandesite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Trachyandesite belongs to Igneous Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Trachyandesite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Conglomerate is Clastic. Trachyandesite appears Dull and Soft and Conglomerate appears Shiny and Rounded. The luster of Trachyandesite is earthy while that of Conglomerate is dull. 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 Trachyandesite are creating artwork, pottery and that of Conglomerate are cemetery markers, in aquifers, tombstones.
