PETROLOGIC DATA

Rock Number: 1

Rock Type:
Field Description:

-this outcrop is odd (it is also 5:20 as unsual)
-into a cataclastitic/mylonite zone
-this looks like another example of tectonic interlayering of diverse rock types, most of which are reduced to augen gneisses and layered mylonite gneisses
-several layers are identifiable as intrusive-a pink leuco granite that looks late and a grey augen TNLT that looks like CWB
- in with it are slices of GR-MV same as last station, HB wackes as previous station and even an amphibolite with intrusive texture that could be a gabbro
-in general supracrustal layers are separated by mylonitic granite or augen TNLT
-the whole point is much the same but with MV-GR sandstones dominant to north and mafic wackes and "gabbro" to south
