PETROLOGIC DATA
Rock Number: 1
-dominantly sedimentary sequence
-interlayered white, grey and black cataclastic gneisses seems to comprise interlayers of quartz rich sandstone, sheared psammitic gneiss and hornblende rich amphibolitic wacke
-minor massive ampb-discontinuous
-deformation is so high that all I'd speculate is that it is a sedimentary sequence and may be upper cycle
-a-[sammitic is - amphibalitic wacke - c-quartz rich sandstone
Rock Number: 2
-pink laminated mylonite gneiss
-occurs as sills through the seds.
-averages 30 cm, max. 1.2 m
-could be derived from previous grey granite or augen pink granite
-cut by numerous pegmatite/aplite seams
