A)Magmatic differentiation
B)Hydrothermal alteration
C)Decompression melting
D)Partial melting

Question

Quizplus · Accepted Answer

Magmatic differentiation is the process by which a single parent magma can give rise to multiple secondary magmas with distinct chemical and mineralogical characteristics through various physical and chemical processes such as crystal settling, assimilation, and fractional crystallization. Hydrothermal alteration involves the interaction of hot fluids with pre-existing rocks which can modify their original mineralogy and chemistry. Decompression melting occurs when pressure on a rock is reduced leading to the melting of the rock. Partial melting is the process by which only some minerals in a rock melt while others remain solid.
