Yttrium zoning in garnet from the Xihuashan granitic complex and its petrological implications

引用

Chinese Science Bulletin 2003年第15期48卷 1611-1615页

作者： WANG Rucheng, HU Huan, zhang aicheng, XU Shijin & WANG Dezi State Key Laboratory for Mineral Deposits Research, Department of Earth Sciences, Nanjing University, Nanjing 210093, China Correspondance should be addressed to Wang Rucheng (e-mail: rcwang@***) State Key Laboratory for Mineral Deposits Research Department of Earth Sciences Nanjing University Nanjing China

The Xihuashan granitic complex is characterized by enrichment in rare-earth elements (REE). In particular, the second-stage granite (G-b) is markedly enriched in yttrium, and therefore contains complex associations of Y-bearing minerals. In this granite, garnet displays specific yttrium zoning with an Y-rich core and a 揷lean?rim. Besides minute inclusions of Y-bearing minerals, garnet involves a striking amount of Y and HREE in its central area. It is suggested that enrichment in Y in the garnet core accords with that in the melt as a result of REE magmatic fractionation. However, the 揷lean?rim may be the direct result of accumulation of fluid phases in the magma, which is virtually unfavorable for the entrance of REE in the garnet structure.

自然界中最常见的铯矿物主要有铯沸石、富铯的云母类矿物和富铯的绿柱石类矿物,它们产于稀有金属花岗岩和LCT(Lithium-Cesium-Tantalum)型稀有金属伟晶岩脉体的中心部位或围岩接触带附近,形成于初始富含铯和挥发组份、处于稳定构造环境且经过高度演化分异的原始花岗质岩浆.由于天然富铯矿物中铯含量一般可达15%,它们的合成相可作为核废料中放射性元素137Cs的前景载体相,而且富铯矿物各自的化学成分和结构等矿物学特征,对137Cs核废物载体相及相应的深埋藏地质环境的选择和载体相在不同地质环境下的行为预测都有较好的指导意义.
