<u>Called as mantel melting</u>
Explanation:
- The mantel rocks can break and melt without the increase in temperature due to the overexerted pressure of the rocks.
- This process is called decompression melting. Rocks can melt in the mantel due to dehydration thus producing molten magma and lava.
- As the rocks don't melt homogeneously there is a complex mixture of mineral content during the subduction and presence of volatile substances like the water or CO2.
