clinkstone

/ ˈklɪŋkˌstəʊn /

noun

(c.) Phonolite (Clinkstone) is a trachytic rock, composed essentially of sanidine, nepheline, and augite or hornblende.

A fissile texture is occasionally assumed by clinkstone and other trap rocks, so that they have been used for roofing houses.

Some varieties are slaty, and are frequently mistaken for clinkstone, which they closely resemble.
