WebMelting of solid rock to produce magma is commonly caused by reducing pressure. This occurs when solid rock is buried to great depths within the Earth's crust where temperatures are high, but pressure is also high due to the weight of the overlying rock. Web6 mei 2024 · Although there are many exceptions to this trend, mafic magmas typically have 1% to 3% volatiles, intermediate magmas have 3% to 4% volatiles, and felsic magmas have 4% to 7% volatiles. Differences in viscosity and volatile levels have significant implications for the nature of volcanic eruptions.
