Formation
Theralite 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.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
