WebA migmatite is a metamorphic rock formed by anatexis that is generally heterogeneous and preserves evidence of partial melting at the microscopic to macroscopic scale. Migmatites represent the transition from metamorphic to igneous rocks in the rock cycle. WebTexture refers to the sizes and shapes of grains, the relationships between neighboring grains, and the orientation of grains within a rock. They are small scale features in a rock that are penetrative, which means that the texture occurs virtually throughout the rock bodies at microscopic scale. flow weighted composite sampleWebLooking for crystalloblastic texture?
