STRUCTURAL DATA

Planar Structures:
Structure type Strike Dip Separation
cataclastic foliation 331 64
schistosity 49 62

Dikes and Sills:
Rock Number Type Width (m) Strike Dip
0 pegmatite 0.00 49 62

-strong set of late 050 PGMT's
-take note of the odd direction of cataclasis and igneous layering
-this 330-340 degree is older than the 050 which folds it and offsets layering
