Abstract:

本文样品是采自中国大陆科学钻探(CCSD)主孔的含金红石榴辉岩,在这些样品中常常含有锆石副矿物,锆石可以呈粒间矿物存在,也可以包裹在其他矿物(如石榴子石、金红石)中。背散射电子图像(BSE)显示这些锆石包裹体的亮度较弱,颗粒较小(约10~30μm),发育多晶面,晶体内部结构和成分均匀。采用能谱分析(EDS)方法来测量锆石的元素成分含量,结果表明:1这些锆石具有很高的Hf含量,金红石中达到1.51%~2.45%,石榴子石中为1.77%~2.13%;2Zr/Hf值约为35.92,比一般的基性原岩中的锆石的Zr/Hf值明显要低,这些特征说明它们很可能是形成在超高压条件下的变质锆石。
