X-ray Crystallography: X-ray Crystallography is a technique in crystallography in which the pattern produced by X-ray diffraction through the closely spaced lattice of atoms in a crystal is recorded and then analyzed to reveal the nature of that lattice. Uses: X-ray...

Miller Indices: Miller indices for crystallographic planes are the reciprocals of the fractional intercepts (with fractions cleared), which the plane makes with the crystallographic x, y, and z axes of the three nonparallel edges of the unit cell. It consists of a...

Crystal twinning is the symmetrical intergrowth of two or more crystals, related by a symmetry operation known as a twin element. Twin elements can include mirror planes, rotation axes (typically two-fold), and rotation inversion, which are distinct from the natural...

Crystal symmetry refers to the regular arrangement of faces, edges, and other structural features in a crystal. This regularity constitutes the crystal’s symmetry. The degree of symmetry varies in different minerals and is employed in the classification of...

A Crystal system includes all the symmetry classes that share a similar constant of lattice parallelepiped. The classes are grouped into six crystal systems based on the absence or presence of certain types of rotation axes. Also, we can say that the basis of...

Before we learn about mineral types, we must know what minerals are. There are a few characteristics before we identify or call a mineral. Characteristics are: Naturally Occurring – Substances produced in the lab or the industry are not...
