通过对亳县陨石中一颗斑状橄榄石球粒的分析，研究了该球粒的凝聚和结晶作用。结果表明这种球粒是由气体直接凝聚成超饱和的亚稳熔体液滴，而后熔体中结晶出成分较均一的橄榄石斑晶。由于温度迅速下降，残余熔体被“冻结”成为玻璃质。同时球粒熔质中橄榄石的结晶，导致残余熔体朝富Ｃａ、富Ａｌ方向演化，形成富Ｃａ、Ａｌ的球粒玻基。 Through the analysis of a porphyritic olivine pellet in the meteorite in Bo County, the cohesion and crystallization of the pellet were studied. The results show that the pellets are directly condensed by gas into super-saturated metastable melt droplets, and then the melt is crystallized into a more uniform olivine plaque. As the temperature drops rapidly, the residual melt is “frozen” into vitreous. At the same time, the crystal of olivine in the pellet melt leads to the evolution of the residual melt towards Ca-rich and Al-rich phases, forming a Ca-rich and Al-containing pellet.
