PETROLOGIC DATA

Rock Number: 1

Rock Type: multi-component schlieric gneiss

Field Description:

-complex mixture of CWB TNLT at least 2 probably 3 generations of TNLT of fine grained grey siliceous TNLT that I haven't encountered before
-a medium grained buff weathering Leuco-GRDR
-deformation comprises migmatite light flowing and disharmonic folding
-cataclasis is not particularly strong
-there are scattered inclusions of amphibolite strung out on the foliation plane
-there is a possibility that some of the pale felsic gneisses could be resorbed sediments
