Crystal Faces • Common crystal faces parallel surface of unit cell, e.g., - isometric minerals often cubes - hexagonal minerals often hexagons • Other faces often simple diagonals through lattice • Codified into two laws: (1) Law of Hauy: - Crystal faces make simple rational intercepts on crystal axes (2) Law of Bravais: - Common crystal faces are parallel to lattice planes that have high lattice node density Miller Indices • Shorthand notation for axial intercepts - works because of Law of Hauy • Miller index = integers that are inversely proportional to intercept of face or crystallographic plane with edges of unit cell.
