Feb 18, 2011 (A Wilson) - The granite pegmatite breccia occurs as matrix supported mono-mineralic and poly-mineralic clasts from 2- 10 cm in diameter in both clast-supported and matrix-supported configurations. The clasts comprise unstrained crystals of quartz and microcline which are apparently very well cemented by a medium to coarse grained cataclastic matrix. In one identifiable dike with offsets the breccia which is clast-supported averages a width of 15 metres for some 300 metre length. Vertical joint separation averages in excess of 15 metres. In another occurrence the dike of matrix-supported breccia is 130 metres wide. The purple and pink migmatite is a composite layered rock generally containing medium to coarse grained layers of the felsic gneiss and a regular fine to medium grained purple or mauve layer comprising quartz, feldspar, biotite, almandine and hematite. Frequently a milky to buff rock of medium to coarse grained. The amphibolite gneiss is a medium greyish black, medium to coarse grained, thinly to thickly layered rock. The amphibolite flanks a thick continuous granite pegmatite dike and the various textures in evidence reflect the gradational and tectonic boundary relationships between the two units.
