Dislocation-related defects in minerals govern globally important rheological processes such as mantle convection in the deep Earth where dislocation creep is a common deformation mechanism of the constituent minerals. Understanding such processes requires the direct observation of individual dislocations in minerals and across their interfaces. Using electron channelling contrast imaging (ECCI) in a conventional field emission scanning electron microscope (FE-SEM), we successfully observed… 
Direct observation of dislocation nucleation in pyrite using combined electron channelling contrast imaging and electron backscatter diffraction
Crystal‐plastic deformation is one of the main mechanisms that can accommodate large amounts of strain within the lithosphere. Despite the requirement of understanding dislocation nucleation and
Advances in electron channelling contrast imaging and electron backscatter diffraction for imaging and analysis of structural defects in the scanning electron microscope
In this article we describe the scanning electron microscopy (SEM) techniques of electron channelling contrast imaging and electron backscatter diffraction. These techniques provide information on
Scanning Electron Microscopy versus Transmission Electron Microscopy for Material Characterization: A Comparative Study on High-Strength Steels
Detailed comparison of the microstructure characterization of quenched and tempered high-strength steels with TEM and SEM electron channeling contrast techniques is presented to help the material science community develop characterization techniques at lower cost and higher statistical significance.
Transmission Kikuchi diffraction study of submicrotexture within ultramylonitic peridotite
Deformed polycrystalline rocks show various crystallographic textures reflecting their imposed deformation histories. However, the textures of ultrafine grains, which are in the submicrometer to
Electron channeling to achieve the full potential of mineralogy
Electron channeling phenomena in electron microscopes are under the spotlight. The determination of site occupancies of select atoms in mineral structures is one of the most intriguing targets in
Defects in olivine
Abstract. Olivine, a ferromagnesian orthosilicate, is the most abundant mineral in Earth's upper mantle and is stable down to the olivine–wadsleyite phase transition, which defines the 410 km depth


The application of electron backscatter diffraction and orientation contrast imaging in the SEM to textural problems in rocks
Abstract In a scanning electron microscope (SEM) an electron beam sets up an omni-directional source of scattered electrons within a specimen. Diffraction of these electrons will occur simultaneously
Scanning electron microscope observation of dislocations in olivine
Dislocations in olivine decorated by oxidation in air were observed with a scanning electron microscope (SEM) using a backscattered electron image (BEI). The decorated dislocations (and grain
Deformation Analysis of Forsterite Olivine Using Electron Channeling Contrast Imaging and Electron Backscatter Diffraction
The dynamics of the Earth system is expressed in a number of ways such as earthquakes, mountain building and plate tectonics. The rheology of Earth materials at the conditions of Earth’s interior
Rotation contour contrast reconstruction using electron backscatter diffraction in a scanning electron microscope
The microstructure of a deformed Mg–Al–Ca alloy was imaged using an electron-beam energy of 20 keV in a cold field-emission scanning electron microscope. The backscattered electron (BSE) micrographs
A dynamical theory for the contrast of perfect and imperfect crystals in the scanning electron microscope using backscattered electrons
Abstract A many-beam dynamical theory, which apporoximately takes into account multiple inelastic scvattering, has been formulated and used to calculate the intensity of electrons backscattered from
Orientation contrast imaging of microstructures in rocks using forescatter detectors in the scanning electron microscope
Abstract We have developed a system using 'forescatter detectors' for backscattered imaging of specimen surfaces inclined at 50−80°C to the incident beam (inclined-scanning) in the SEM. These
