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

Chemically active fluids aid in the movement of dissolved ions and silicate constituents from parent minerals and facilitate growth of new metamorphic mineral grains. This is a major effect of chemically active fluids during metamorphism. They help in the development of new crystal structure and textures in rocks.
