Luster of Minerals Geology In

Minerals possessing metallic luster are opaque and very reflective, possessing a high absorptive index. This type of luster indies the presence of metallic bonding within the crystal lattice of the material. Examples of minerals which exhibit metallic luster are native copper, gold, and silver, galena, pyrite, and chalcopyrite.
