摘　　要：对地质矿物中的尖晶石-富钙辉石难熔包体进行了矿物化学研究,包体近似球形,边部为斜长石和橄榄石层。包体中残留颗粒较小的铁镍金属,包体外部形态不是由气-固凝聚形成,大多数情况下是由于熔融结晶形成,本文结合前人对难熔包体的研究,更清晰的描述了不同类型难熔包体的特征,我们按照富钙-铝包体中的主体矿物或矿物颗粒的大小来对难熔包体类别进行区分,有助于对难熔包体的分类进行深入研究。In this paper,the MINEROCHEMICAL study of spinel rich pyroxene refractory inclusions in geological minerals is carried out.The inclusions are nearly spherical,with plagioclase and peridotite layers at the edge.In this paper,the characteristics of different types of refractory inclusions are described more clearly based on the previous research on refractory inclusions.According to the size of the main minerals or mineral particles in the calcium aluminum rich inclusions,the types of refractory inclusions are classified It is helpful to study the classification of refractory inclusions.
