An intriguing introduction to mineralogy and to related specialities such as petrology.Gems, Granites and Gravels is a valuable introduction to mineralogy and to related specialities such as petrology, crystallography and soil science. Discoveries in these fields are described in a historical context, while the authors explain what minerals and rocks are, how they are distributed around the world, how we depend on them, and where to see the most beautiful specimens of both minerals and rocks.Gems, Granites and Gravels is a valuable introduction to mineralogy and to related specialities such as petrology, crystallography and soil science.
