| 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. |
