Abstract

A low-cost universal stage with an angular resolution of 1.8 degrees is described; it can be mounted on an ordinary powder X-ray diffractometer. The attachment is used to characterize the microstructure (orientation of mineral grains). Microstructures of polycrystalline materials of diverse origin (eggshell, tufa and mollusc shell) were characterized by registering the intensity of diagnostic lattice reflections for a particular mineral in 3D space using a polar coordinate plot (hemispherical projection). Pole figure distributions were used to decipher the potential growth mechanisms that produced the observed microstructures in these mineral aggregates.
