Chapter 7 A review of the current status of the Older
The Older Metamorphic Group and the Older Metamorphic Tonalite Gneiss are classic examples of Palaeaoarchaean high-grade metamorphic rocks of the Singhbhum Craton of India. The Older Metamorphic Group is a supracrustal assemblage that was probably deposited as a greenstone belt-type succession before c. 3.32 Ga, the low-grade equivalents of which are found in parts of the Iron

What Makes Metamorphic Rocks So Unique?
Sep 18, 2019 · As strain increases, the foliation becomes more intense, and the minerals may sort themselves into thicker layers. The foliated rock types that form under these conditions are called schist or gneiss, depending on their texture. Schist is finely foliated whereas gneiss is organized in noticeable, wide bands of minerals.
