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

Chemically active fluids aid in the movement of dissolved silicate constituents and facilitate growth of the mineral grains during metamorphism. This can result in the formation of new minerals, changes in texture and structure, and the development of foliation or banding.
