How can contact metamorphism result in the deposition of ore deposits?
A)Magma differentiates during cooling, leaving the ores to settle out to the bottom of the magma chamber.
B)Hot, mineral-rich water exits the seafloor, resulting in instant precipitation of minerals.
C)Hot magma burns the country rock, which experiences a mineral phase change.
D)Hot fluids in contact with the country rock can result in chemical reactions that facilitate the migration of metallic ions.
