PETROLOGIC DATA
Rock Number: 1
Multi-component schlieric gneiss
Extremely complex gneiss assemblage. Seems to have several components:
1. Base rock is old grey tonalite
2. Pods of younger grey porphritic granodiorite
3. Numerous ages of simple pegmatites lit
4. Amphibolite rafts - massive
5. Rafts and schlieric zones of fine grained grey psammitic textured rock - unknown rock type. Resembles greywacke metatexite - could be inclusion of early sediment or leucocratic fine early intrusive
