STRUCTURAL DATA
Structure type | Strike | Dip | Separation |
---|---|---|---|
schistosity | 130 | 75 |
-foliation and layering appear to be parallel although there also appears to be some minor cataclasis at a slightly divergent angle that confuses the pattern
PETROLOGIC DATA
Rock Number: 1
-siliceous grey white psammite containing 60 to 65 % quartz permeated containing black muscovite nods
-plane of flattening is dominantly the foliation plane but there is some random orientation of the muscovite plates
-some units appear to have blastic plagioclase while the outcrop is largely psammitic there is around 10% muscovite rich semi-pelite
-there are scattered hornblende diopside calc-silicate layers
-in general, this can probably be correlated containing the SNDS to the E of Middle Channel
