PETROLOGIC DATA
Rock Number: 1
-Pinkish grey weathering, homgeneous
-has numerous 1 to 3 mm oval HM stains
-rock is PORT with MC phenocrysts up to 1 cm
-there may also be phenocrysts of quartz up to 5 mm
-the rock has an unusual textural appearance unlike anything associated with CWB
-THe impression it leaves is of a young rock even though it is strongly foliated with AUGN-MEGA.
-the nearest occurence that this reminds me of the grey PORT from Spod Bay
-this represents an interesting possibility as the position in a structural sense is equivalent for the two bodies
-this rock should be chemically analyzed
-GRDR is cut by numerous pink pegmatites with pearly-lustery white or pale green primary MC's, GR, TL and bright waxy green MV.
-There are wispy inclusions of fine grained, grey, GRDR and also appears to be slightly PORT
