5 Formation

5.1 Formation

Trachyandesite 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.

Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
