Shear zone with a op-to-the NE sense of shear in the high-grade metamorphic rocks with granulite facies relics, Wilson Terrane, Ross Orogeny (Antarctica). The age is nearly 440 Ma.
\nIn the lower part: dolerite dyke; in the upper part amphibolites. A small leucogranite dyke is progressively deflected and stretched entering in the shear zone. PhotoID193<\/p>\n
