[QUOTE="user 4386, post: 653216, member: 4386"] It is visible. It is mostly with the quartz. Originally it was a normal gold-quartz vein containing gold, arsenopyrite and pyrite with probable white mica margins. It was buried to great depth (higher temperature and pressure) to the point where minerals reacted with each other and it partly melted to form a pegmatite . The original micas formed feldspars and kyanite (from memory), the arsenopyrite-pyrite converted to lollingite-pyrrhotite and the veins became tightly folded and dismembered - so discontinuoius clumps of pegmatitic material.
