May 07, 2013 (A Wilson) - A railway cut exposes a large pink syenite pegmatite dike cutting hornblende-plagioclase gneiss. The pegmatite has irregular patches and veins of apatite-fluorite-carbonate. The veins range in sized from 5 cm to 1 m in width and are very irregular in shape. The area is underlain by marble, quartzo-feldspathic gneisses, minor biotite-hornblende paragneisses and calc-silicate gneisses.
