WebView history. In crystallography, a crystallographic point group is a set of symmetry operations, corresponding to one of the point groups in three dimensions, such that each operation (perhaps followed by a translation) would leave the structure of a crystal unchanged i.e. the same kinds of atoms would be placed in similar positions as before ... WebMineralogy is the systematic study that deals with the characteristics of minerals. The mineralogy has more scientific branches such as the following: 1. Crystallography studies crystal forms, i.e. forms in which the minerals crystallize, as well as their internal structure, relations and distribution of atoms, ions or ionic groups in the crystal lattice.

WebThe emergence of crystallography (study of crystals) as an independent science was directly related to the development of optical instruments. Once the angles between crystal faces could be accurately measured then minerals could be described. The instrument developed to measure these interfacial angles became known as a goniometer.
