Definition

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

Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase

Formation

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

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.

All about Conglomerate and Anorthosite Properties

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