Porphyry
Definition:
(n.) A term used somewhat loosely to designate a rock consisting of a fine-grained base (usually feldspathic) through which crystals, as of feldspar or quartz, are disseminated. There are red, purple, and green varieties, which are highly esteemed as marbles.
Example Sentences:
(1) Sometimes fragments of the giant Reichschancellery, due to the recycling habits of East Germans, are seen: the walls and platforms of one U-Bahn station are inlaid with great lumps and plates of porphyry, fragments prised from the floors across whose glassy and obsessively waxed surfaces foreign dignitaries once had to pick their way into the Führer's presence.
