WebLecture Crystallography - University of Notre Dame WebCrystal twinning occurs when two or more adjacent crystals of the same mineral are oriented so that they share some of the same crystal lattice points in a symmetrical manner. The result is an intergrowth of two separate crystals that are tightly bonded to each other. The surface along which the lattice points are shared in twinned crystals is called a …

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.
