-this outcrop adn north flanked TNLT seem to be a slightly younger outcrop
-north flank was peristerite and called unit 9c by rousell
PETROLOGIC DATA
Rock Number: 1
-light grey white weathering med. grained TNLT --> GRDR
-variable 1 to 2% white MC megacrysts
-GR maybe assoc. with margins or near the margins of the in situ developed pegmatites
-fabric is shown by weak BO-foliation and quartz aggregate alignment
-appears to be the same unit as on north flank in SW Spod. Bay--young 'club' TNLT
Mineral | Abundance (%) |
