Definition

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

Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava

Formation

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

Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

All about Conglomerate and Andesite Properties

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