Galena rocks
Specimens. Galena is a common and popular mineral for rock hounds. Its characteristic cubes, distinctive cleavage and high density make it easy to identify and a favorite in high school geology labs. The structure of Galena is identical to that of halite, NaCl. The two minerals have the same crystal shapes, symmetry and cleavage.10 x 7 x 4.5 cm - Cabinet. Tagged. ore mineral, sulfide.
