镁铁质-超镁铁质岩体含矿性评价指标体系——应用于寻找岩浆硫化物矿床

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 system consists of tectonic setting, the nature of magma source region, original magma, rock types, magmatic differentiation degree, mass balance, magmatic water content, assimilation, mineralogy, chemistry of rock-forming minerals, geochemical of major elements, geophysical and geochemical anomalies. The index syst em is set up initially, it requires a continuously deepening and improving process.
