The usual main purpose of the zircon investigation is to determine the precise age of particular rocks, applying the U-Pb isotope method. In this study we attempt to reveal the vast potential of zircons in understanding the magmatic and modification

The man-made periodical patterns executed in textile are especially suitable for the study of plane groups. The diversity of geometric patterns can be described based on the symmetry classification of the two-dimensional symmetry, anti-symmetry and c
