Above Centre Pass, Dusky Track
Just a short climb above Centre Pass (1050m) toward Mt Memphis (1405m) you reach the ridge bristling with tarns. The rock exposure is superb. Fiordland gneiss, I suspect. This is heaven on earth for a geologist. Beautiful structures, leucosomes, etc. Well worth the 30-40 minute climb up from the pass. Mt Memphis is a further 20-30m along the ridge.

Roderick In gneiss or migmatie (high grade metamorphic rocks), you see these segregations of light and dark bands. These bands can often be very folded and contorted. The light-coloured ones, which may represent the beginnings of granite liquid separation, are known as leucosomes. I have a rather poor photograph of one of these, but if you look carefully, you can see these irregular contorted white segregation bands - these are the leucosomes I refer to.

matthew Beautiful. Just curious: do you have a photograph of a leucosome?
