BYTOWNITE , a See also:rock-forming See also:mineral belonging to the See also:plagioclase (q.v.) See also:series of the felspars. The name was originally given (1835) by T. See also:Thomson, to a greenish-See also:- WHITE

white felspathic mineral found in a See also:boulder near Bytown (now the See also:city of See also:Ottawa) in See also:Ontario, but this material was later shown on microscopical examination to be a mixture. The name was afterwards applied by G. Tschermak to those plagioclase felspars which See also:lie between See also:labradorite and See also:anorthite; and this has been generally adopted by petrologists. In chemical See also:composition and in See also:optical and other See also:physical characters it is thus much nearer to the anorthite end of the series than to See also:albite. Like labradorite and anorthite, it is a See also:common constituent of basic igneous rocks, such as See also:gabbro and See also:basalt. Isolated crystals of bytownite bounded by well-defined faces are unknown. (L. J.
