Geology and hydrothermal evolution of the Baituyingzi porphyry Mo (Cu) deposit, eastern Inner Mongolia, NE China: Implications for Mo and Cu precipitation mechanisms in CO2-rich fluids
Fluids are primarily of magmatic origin at Baituyingzi. Fluids belong to a vapor-dominated H2OCO2NaCl system. Cu precipitation is promoted by a decrease in temperature to below 400 °C. Mo deposition is a result of water-CO2 immiscibility below 350 °C.
