REE in two samples of augite skarns from Inner Mongolia were determined by the method of ICAP. It has been discovered that in the condition of contact metasomatism the diagram of normalized REE patterns of rocks show "REE tetrad effect" characterized by four concave curves joining each other and may not follow Coryell rule on smooth curves for REE patterns.The REE tetrad effect express that REE exist in the form of stable complex ions in the basic water solution of early stage during the formation for the skarns and it is difficult for REE in large quantities to enter into augite skarns forming earlier, so the REE contents of the augite skarns from Inner Mongolia are very low.

通过对内蒙白音诺和浩布高两地区辉石矽卡岩中稀土元素(REE)的测定,证明了在接触交代作用的条件下,岩石中REE分布模式可以不服从Coryell关于球粒陨石标准化后的曲线是一条平滑曲线的规律,而是呈现出以4条相连的凹形弧线为特征的“四分组效应”。辉石矽卡岩中REE的“四分组效应”的存在,为进一步研究矽卡岩形成的某些物理化学条件和REE在矽卡岩形成过程中的地球化学行为提供了新的途径。
