Rock Types??? HELP!!?!?!?!?

Okay, so Iggy is an igneous rock during the last ice age. He's formed in an oceanic rift, like in Greenland. That's how you can fit in plate tectonics. In the second paragraph, he experiences both physical and chemical weathering. Physical: freeze-thaw cycle breaks him into pieces. Chemical: glacial river dissolves him and washes him downstream. In the next paragraph, he is deposited in a glaciomarine delta. That's deposition. The sea level recedes as the glacier melts and the area experiences rebound, and that delta becomes a soil as organic matter is added.
