Molybdenite Re-Os age, H-O-C-S-Pb isotopes, and fluid inclusion study of the Caosiyao porphyry Mo deposit in Inner Mongolia, China
文摘
The Re–Os dating indicates that the Caosiyao deposit formed at ca. 150 Ma. The ore-forming fluids are moderate–high temperature and great fluctuating salinity fluids. The ore-forming fluids of the deposit consist mainly of magmatic water. The ore-forming materials of the deposit mainly came from the Mesozoic magma. The multistage fluid boiling was the dominant mechanism for the deposition of materials.
