During metamorphism, what is the major effect of chemically active fluids like water and carbon dioxide?
A) aid in the movement of dissolved ions and silicate constituents from parent minerals and facilitate growth of new metamorphic mineral grains
B) facilitate the formation of schistosity and gneissic banding in hornfels and skarns
C) increase the pressures in deeply buried, regional- metamorphic zones
D) prevent partial melting so solid rocks can undergo very high temperature regional metamorphism

Question

Quizplus · Accepted Answer

Chemically active fluids such as water and carbon dioxide play a crucial role in metamorphism by aiding in the movement of dissolved ions and silicate constituents. This process facilitates the growth of new metamorphic mineral grains by enabling the transport and rearrangement of materials within the rock.
