【摘要】 本文利用电子衍射、电子显微像和晶格像，研究了湖北大冶铁山矿床中葡萄石的完整／不完整晶畴、位错、堆垛层错、复杂界面和斑点状衍射衬度等微结构特征；并从地质温度压力特征、各种电镜现象和葡萄石、绿纤石和多硅白云母晶胞参数特征，探讨了三种矿物形成纳米级拓扑定向晶格共生的机理更多还原

【Abstract】 The paper presents the study on TEM microstructural characteristics of perfect and imperfect crystal domain,dislocation,stacking fault,complicated interface and motted diffraction contrast observed in the prehnite from Tieshan iron mineral deposit,Daye,Hubei province by electron diffraction pattern,electron micrographs and lattice images.Meanwhile,the formation mechanism of nanotopotactical intergrowth of prehnite,pumpellyite and phengite and muscovite is discussed according to the characteristics of geotemperature and geopressure,the observed of TEM phenomena and the cell parameters of the three minerals. 更多还原
