Key Concepts

Flux Melting

Flux melting refers to the phenomenon where the addition of volatiles, especially water, reduces the melting point of rocks. This process is important because even a small amount of water can cause mantle rocks to melt at temperatures where they would normally remain solid in dry conditions.

Mantle Rock Behavior under Extreme Conditions

Mantle rocks exist under high pressure and temperature conditions deep within the Earth. The melting behavior of these rocks is highly influenced by these parameters as well as by their chemical composition. The introduction of water can lower the solidus—the temperature at which melting begins—thus initiating partial melting even when conventional temperatures are insufficient.

Role of Volatiles in Magmatic Processes

Volatiles such as water are critical in driving magmatic processes and volcanic activity. They influence the physical properties of mantle rocks, facilitating melting and thereby playing a significant role in the generation of magma. This volatile-induced melting is a key concept in understanding the dynamics of Earth's interior and the formation of magmatic systems.
