Jan 27, 2017 (A Wilson) - This locality is near the extreme southerly end of the nepheline syenite band, the specimens being collected on the south side of the Monck road where it crosses this lot. The rock is rather coarse in grain with a crude foliated structure, and is dark in colour, being rich in iron-magnesia constituents. Little red specks can be seen dotting the fresh surface of fracture, and consisting of the altered nepheline. This mineral is not very abundant in the rock as a whole, but occurs in large masses in certain coarser grained schlieren, where it is often associated with zircon crystals.
