Mark with small triangles the site where the youngest igneous rocks are.
Bonus points for an example.
Collisional mountain belts have a long and complex history. For example, the Himalayas have been forming over a period of 40 million years. Put the following processes that shape mountain belts in a reasonable geologic order starting with 1 as the earliest in the progression. Draw a picture of what a fold might look like in the deep, soupy migmatite bowels of a mountain belt. Circle the one that requires some sort of seal.
