Similar relationship to that shown in MS-03 but with some interesting differences. The gneiss in the foreground has a porphyroblastic texture: large white feldspar crystals are set in a finer matrix. These may represent feldspar megacrysts from an originally magmatic, broadly granitic rock. Note that felsic material invades the margin of the amphibolite unit. This may indicate that the "granitic" material was mobilised (by partial melting) during injection of the basic magmatic sheet and that this resulted in back-veining of the sheet. Alternatively, the mobilisation could have occurred during subsequent metamorphism.
