5.1 Formation

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

Hornblendite 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.
