Dec 05 2020 0183 32 Minerals are the building blocks of rocks and therefore are the building blocks of our planet s structure They are specifically defined as naturally occurring crystalline as used in mineralogy this means that they have an ordered internal structure solids that are made inorganically not by biological methods...

Crystal structure

Unit cell Crystal structure is described in terms of the geometry of arrangement of particles in the unit cell The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure The geometry of the unit cell is defined as a parallelepiped providing six lattice parameters taken as the lengths of the cell edges a b c and the angles between them α...
