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.

Abstract: 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.
