PETROLOGIC DATA

Rock Number: 1

Rock Type: amphibolite
Descriptors:
layered
MLNT
Field Description:

-cm layered sheared sequence of black amphibole gneiss and grey siliceous sandstone
-primary layering is completly destroyed and transposed into the shear
-the sequences was probably sedimentary interbedded tuffs and sandstones
-the units are discontinuous in the mylonite but may reach dimensions of 10 cm x 4 m
-the angle between primary layering and shear may have been fairly low
-as usual these are 10 to 20 m pink granite mylonite layers
