Mineral resource of the month: Garnet. Garnet is the general name given to a group of complex silie minerals, all with isometric crystal structure and similar properties and chemical composition. The most common garnet minerals are classified into three groups: the aluminumgarnet group, the chromiumgarnet group and the irongarnet group.

Smectite Group: Mineral information, data and localities.

Prior to circa 1975, the smectite group was called the montmorillonitesaponite group. Smectite minerals have large specific surface areas (10 700 m2/g) and exhibit a high expansion (swelling) capability in the presence of H2O. Smectite and vermiculite minerals are often referred to as "swelling" or "expandable" clay minerals.

Division of Geology and Mineral Resources Clay Materials

The se minerals belong to the clay mineral group distinguished by a layered crystal lattice structure that allows for the exchange of calcium, sodium, potassium, among other ions. This property makes certain clay minerals useful in industrial appliions for adsorption, filtration, oil refining, and as additives in paint and paper manufacture.

Environmental Characteristics of Clays and Clay Mineral

Clay minerals have a wide range of particle sizes from 10's of angstroms to millimeters. (An angstrom is a unit of measure at the scale of atoms.) Thus, clays may be composed of mixtures of finer grained clay minerals and claysized crystals of other minerals such as quartz, carbonate, and metal oxides.

Clay mineral Chemical and physical properties

Clay mineral Chemical and physical properties: Depending on deficiency in the positive or negative charge balance (locally or overall) of mineral structures, clay minerals are able to adsorb certain ions and anions and retain them around the outside of the structural unit in an exchangeable state, generally without affecting the basic silie structure.

1:1 Clay Mineral Structures: Kaolinite and its relatives. Recall that each layer of the 1:1 minerals is made from one tetrahedral sheet linked to one octahedral sheet. The octahedral sheet can be either dioctahedral or trioctahedral, which splits the 1:1 clay minerals into two subgroups. The kaolin subgroup minerals are dioctahedral,
