Protocol for electron backscatter diffraction (EBSD) analysis of fossil eggshells

Choi, Seung ; Park, Yong ; Moreno-Azanza, Miguel (Universidad de Zaragoza)

Resumen: Electron backscatter diffraction (EBSD) is an analytical technique using diffraction patterns (called Kikuchi pattern) originated from the back-scattered electrons diffracted by the lattice plane of the material which satisfies the Bragg’s angle (Baba-Kishi, 2002; Kikuchi, 1928; Nishikawa & Kikuchi, 1928; Prior et al., 1999). The EBSD detector is an apparatus that attaches to either a scanning electron microscope (SEM) or transmission electron microscope (TEM). It is used by diverse fields of geology because EBSD data permit investigation of various mineralogical properties such as phase, grain size, shape, orientation, and boundary information (Prior et al., 2009). This type of analysis was initially introduced to paleontology by invertebrate paleontologists because many invertebrate fossils have mineralized hard parts that are composed of calcium carbonate (CaCO3) and are relatively easy to prepare for EBSD analysis (Pérez-Huerta et al., 2007; see Cusack, 2016; Pérez-Huerta et al., 2018 and references therein)...
