5 Formation

5.1 Formation

Tephrite 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.

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
