Galena contains about 86 percent lead, is very heavy (density of 7.4-7.6), gray in color with a metallic luster, and is easily cleaved. Silver may be an impurity, and if appreciable, it can be a by-product. Galena frequently forms with sphalerite. It is an accessory in granite, rhyolite, and granitic pegmatites and may be found in contact aureoles adjacent to silicic plutons. It is often associated with lithium and tin mineralization. Associated minerals include quartz, feldspar, muscovite, tourmaline, fluorite, cassiterite, apatite, and beryl.Although the galena cube under discussion was symmetrical in surface contour, examination of its interior structure showed that its component blocks did not parallel the surface planes. This de-viation was more pronounced with increase in distance from the outer faces of the cube and amounted to a distinct curvature in the block arrangement. The unit cell of galena has been converted into primitive cell to reduce number of atoms per unit cell. The primitive cell of galena contains two atoms [10]. The geometrical optimization for lattice of galena with respect to the unit cell size and internal positions of atoms has been performed by using the GGA-PBE framework system [25], [26].
