文摘
- •
Metasedimentary rocks occur associated with intrusive amphibolites in a linear belt.
- •
Volcano-sedimentary association confined to the western margin of the BGC-I.
- •
Cannibalism is inferred as cause of heterogeneity in geochemistry and low CIA.
- •
Inferred source rocks include the mafic enclaves and the host basement gneisses.
- •
Aravalli craton was part of the Ur supercontinent.
