STRUCTURAL DATA

Planar Structures:
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

Rock Type: greywacke
Field Description:

-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

Minerals of Note
