Formation

Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

Foidolites 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.
