Abstract根据对新疆阿尔泰3号伟晶岩脉各结构带中磷灰石的微量元素组成的系统研究,并综合了目前世界上对不同演化程度的酸性岩浆岩(I型和S型花岗岩、过铝质花岗岩、花岗伟晶岩)的研究成果,对通常具有相似离子半径和相同离子电价的元素对比值变化以及稀土元素“四重效应”产生的原因进行了分析。研究认为,这些元素对的分异和稀土元素“四重效应”的产生与富含挥发分流体相的存在密切相关,流体/熔体相作用的程度可能是制约元素对分异和稀土元素“四重效应”大小的主要因素。
Other AbstractBased on the studies on apatites from the Altay No.3 granite pegnmtite,Xinjiang,China.together with those peraluminous granites and pegmatites from various刮 in the world, this paper discusses the fractionation of the coherent elemental pairs that have similar ionic radii and SS1Tte valences ,and also the origin of the lanthan ide tetrad effect. It is suggested that the fractionation of the coherent elemental pairs and occurrence of the lan thanide tetrad effect are genetically related to formation of volatile—rich fluid during magmatic evolution,an d that the fractionation of the elemental pairs an d the intensity of the lanthanide tetrad effect ar1e depe ndent on the extent of fluid—melt interactions.
