Jan 25, 2017 (A Wilson) - A large area has been stripped and trenched on a granite pegmatite and quartz syenite pegmatite body intrusive into a larger area of syenite along the southern boundary of the Glamorgan granite mass. In places the pegmatite is highly feldspathic (red microcline) with a very low quartz content but for the most part it contains green to black hornblende. The more hornblendic. parts tend to be plagioclase-rich. An inclusion of coarse-grained syenite within the pegmatite has a marginal concentration of hornblende
