Formation

Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.  
Comendite is a type of Igneous rock which is formed due to cooling and solidification of lava or magma. It may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
