Definition
Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Formation
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Trachyte and Conglomerate Properties
Know all about Trachyte and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Trachyte belongs to Igneous Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Trachyte is Aphanitic to Porphyritic whereas that of Conglomerate is Clastic. Trachyte appears Banded and Conglomerate appears Shiny and Rounded. The luster of Trachyte is metallic while that of Conglomerate is dull. Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Trachyte are cemetery markers, creating artwork and that of Conglomerate are cemetery markers, in aquifers, tombstones.
