STRUCTURAL DATA

Planar Structures:
Structure type Strike Dip Separation
cataclastic foliation 39 73

PETROLOGIC DATA

Rock Number: 1

Rock Type: amphibolite
Descriptors:
layered
hornblende - garnet bearing

Field Description:

-sedimentary amphibolites with old GRDR mobilizate parallel to layering and some injected lee
-extreme deformation has produced a swirled-marble cake texture with total disruption of primary layering
-numerous old quartz veins augened in foliation plane
-some HB and DP layers may be reminents of volcanics
-dominantly the outcrop is fairly fine grained, laminated BO, HB, samitic gneiss
