摘　　要：为了能够快捷、经济地从众多镁铁质-超镁铁质岩体中筛选出有利于赋含岩浆硫化物矿床的岩体,尝试着论述了岩体含矿性评价指标体系。构成该体系的要素包括:构造环境、岩浆源区性质、原生岩浆、岩体类型、岩浆分异程度、质量平衡、岩浆含水量、同化混染、矿物学、造岩矿物晶体化学、主量元素地球化学和物化探异常等。该指标体系仅仅是初步建立,尚需一个不断深化、完善的过程。In order to choose magmatic sulfide deposits faster and more economical from mafic and ultra- mafic intrusions, we try to discuss ore-bearing potential evaluation index system. The evaluation index sys- tem consists of tectonic setting, the nature of magma source region, original magma, rock types, mag- matie differentiation degree, mass balance, magmatic water content, assimilation, mineralogy, chemistry of rock-forming minerals, geochemical of major elements, geophysical and geochemical anomalies. The in- dex system is set up initially, it requires a continuously deepening and improving process.
