| 摘 要： | 本文利用EXAFS方法对镁铝榴石、几种锰矿和不同铁含量的闪锌矿中有关阳离子的近邻结构进行了研究,得到了有关阳离子在相应矿物中的近邻结构参数.对闪锌矿的研究,得到了杂质Fe绝大部分以六配位的形式存在的结果,这与传统的观点不同;提出了闪锌矿不仅可作为地质温度计,还可能作为地质温度、压力变化记录仪的设想。

| Abstract: | The neighbouring structures of some cations in pyrope, Mn-bearing minerals and sphalerite samples with different Fe contents are studied with EXAFS technique.The data of the neighbouring structures have been obtained.The result that most of the iron in sphalerite are 6-fold coordinated is demonstrated and it is different from the traditional idea about the existing form of iron in sphalerite.It is assumed that natural sphalerite not only can be used as a geo-thermometer but also as a recorder of the developments of temperature and pressure. |
