PETROLOGIC DATA
Rock Number: 1
-sandy textured, moderately mafic, probably associated with the volcanics section.
-numerous small garnet - hornblends amphibolite clots
- 80 cm rusty gossan zone within foliation (parallel to layering).
-garnets fractured, highly included with biotite rims.
-layering is quite delicate with "suggestion" of tops overturned, based on grading.
-gossen appears to be associated with a more massive coarse amphibolite. There are several fairly continuous medium grained to pegmatitic granodiorite lit, parallel to bedding.
-pinch and swell and boudinage are common but extensional separation is quite limited.
-there is no evidence of a mobilisate developing in the greywacke
