The Iranian Journal of Crystallography and Mineralogy (IJCM) published quarterly aims to develop and enhance research in crystallography and mineralogy areas and to present the latest scientific research findings at the national level ensuring authors gain maximum impact and visibility for their work. The science of crystallography and mineralogy containing the sub-branches of the academic basic sciences such as geology, chemistry, physics, materials engineering and mining engineering discerns the arrangement and bonding of atoms in crystalline materials according to the principles of crystallography. Crystallography science concerns determining the position of atoms and ions in crystal lattice, the lattice symmetry and the space group of crystal structure. Nowadays, different X-ray based methods are employed to determine the nature of crystalline material, the internal structure and even the chemical composition of materials. Particularly, X-ray diffraction (XRD) is an important method to characterize the structure of crystalline material; X-ray fluorescence (XRF) spectroscopy is a well-established technique used to determine the chemical composition of a wide variety of samples with a detection limit at sub ppm levels. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are utilized for morphological and microstructural analyses. All the researches on the mentioned crystallography and mineralogy-related subjects are in scope of IJCM.
