PETROLOGIC DATA
Rock Number: 1
-moderately sheared volcanic derived seds comprising mixed basalt andesite material
-thin remnants of felsic silts and a lite grey weathering plag quartz HB matrix material
-epidote pods are common
-shearing probably took place at high angle to layering so all beds disrupted and rotated into foliation
-the original rock was probably an interlayered series of mafic mudstones and siltstones, poss. with some thin mafic conglom. horizons
-there may have been basaltic flows within sed. section as there are relativly well preserved massive amphibolite layers
