Kristályrendszerétl
Kristályrendszerétl is a term used in mineralogy to describe a crystal system that does not fit into the standard seven crystal systems: triclinic, monoclinic, orthorhombic, tetragonal, trigonal, hexagonal, and cubic. This category includes minerals that exhibit unique or complex crystal symmetries that do not conform to the regular geometric shapes associated with the standard crystal systems. Examples of minerals that may fall into this category include those with non-periodic or aperiodic crystal structures, such as quasicrystals, or those with highly distorted crystal lattices. The study of such minerals is an active area of research in mineralogy and crystallography, as it challenges traditional notions of crystal symmetry and structure. The term kristályrendszerétl serves as a placeholder for these unconventional crystal forms, encouraging further investigation and classification.
