Final answer:
Deep weathering of feldspar-rich rocks is NOT the result of metamorphism, which is the process of altering rocks by heat and pressure, while weathering is the surface-level breakdown of rocks.The correct option in the final answer is D.
Step-by-step explanation:
The option that is NOT the result of metamorphism is D. Deep weathering of feldspar-rich rocks. Metamorphism involves the alteration of pre-existing rocks by heat and pressure, leading to changes such as the growth of new minerals, development of alignment within the rock body (foliation), and the recrystallization of minerals.
However, deep weathering is a process that happens at the Earth's surface and is related to the breaking down of rocks through chemical alteration and physical disintegration, which is not associated with the metamorphic process.
Conglomerate pebbles deformed into long, elliptical shapes can be a result of pressure applied during metamorphism causing the pebbles to elongate.
