Definition
Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Formation
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

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