Formation
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
