Dodecahedral minerals
WebThe meaning of DODECAHEDRAL CLEAVAGE is cleavage in a mineral parallel to the faces of the rhombic dodecahedron. WebSpecific gravity is the ratio between the mass (weight) of a mineral and the mass (weight) of an equal volume of water. A mineral's specific gravity (SG) can be determined by dividing its weight in air by the weight of an equal volume of water. For instance, quartz with a density of 2.65 is 2.65 times as heavy as the same volume of water.
