Ore-Bearing Potential Evaluation Index System of Mafic and Ultramafic intrusions Used to Search for Magmatic Sulfide Deposits

In Brder to choose magmatic sulfide deposits faster and more economical from mafic and ultramafic intrusions,we try to discuss ore-hearing potential evaluation index system.The evaluation index system consists of tectonic setting,the nature of magma source region,original magma,rock types,mag..matic differentiation degree,mass balance,magmatic water content,assimilation,mineralogy,chemistry of rock-forming minerals,geochemical of major elements,geophysical and geochemicaI anomalies.The index system is set up initially,it requires a continuously deepening and irztproving process.
