PETROLOGIC DATA

Rock Number: 1

Rock Type: amphibolite
Field Description:

-this outcrop is a real mess
-the dominant rock type is basalt and associated mafic sediments
-primary layering is in a general N-S plane with fol. almost at right angles
-the bedding is almost totally disrupted so the outcrop is a random mixture of epidosite bearing basaltic HB ampb, grey BO+/-HB mafic wackes, quartz veins and grey augen leucoGRDR (GR) as transposed layers are stacked lenses
-the last way to represent this zone on the map will have to be as a mixed cataclastic gneiss
