1 Definition

1.1 Definition

Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

5 Formation

5.1 Formation

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

Tachylite 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.
