Clay is a generic term for an aggregate of hydrous silicate particles less than 4 μm (micrometres) in diameter. Clay consists of a variety of phyllosilicate minerals rich in silicon and aluminium oxides and hydroxides which include variable amounts of structural water. Clays are generally formed by the chemical weathering of silicate-bearing rocks by carbonic acid, but some are formed by hydrothermal activity. Clays are distinguished from other small parti ...

Gibbsite, Al(OH)3, is an important ore of aluminium and is one of three minerals that make up the rock bauxite. Bauxite is often thought of as a mineral but is really a rock composed of aluminium oxide and hydroxide minerals such as gibbsite, boehmite (AlO(OH)), and diaspore (HAlO2), as well as clays, silt, and iron oxides and hydroxides. Bauxite is a laterite, a rock formed from intense weathering environments such as foun ...

Bentonite Clay and its spiritual properties: Intestinal cleanse of the colon is strongly recommended by Kalki and The Golden Age Foundation in order to be fully receptive for pranic energy. It is so vital that it should be the mandatory preparation before all deeper spiritual processes and as a continous maintenance of the body as an antenna of cosmic energies. Bentonite (also available at many pharmacies under alternative substance names to bentonite: bentonitum, montmorillonite) is believed to have exceptionally properties. This article from www.alternativemedicine.com desribes the genereal properties and use of bentonite.

Diamond is one of the two best known forms (or allotropes) of carbon, whose hardness and high dispersion of light make it useful for industrial applications and jewelry (the other equally well known allotrope is graphite). Diamonds are specifically renowned as a mineral with superlative physical qualities - they make excellent abrasives because they can only be scratched by other diamonds, which also means they hold a polish extremely well and retain luster. About 130 million carats (26,000 kg) are mined annually ... Including:

Clays are heavy in texture yet soft to the touch. Clay is a malleable substance when wet, which means it can be shaped easily with the hands. When dry, it becomes firm and when "fired," or hardened by intense heat, clay becomes permanently solid. A fireplace or oven specifically designed for hardening clay is called a kiln. These properties make clay an ideal substance for making durable pottery items, both practical and decorative, with different types of clay and firing conditions giving earthenware, stoneware and porcelain. Early humans d ...

Diamond - Formation. Diamond is formed by prolonged exposure of carbon bearing materials to high pressure and temperature. On Earth, the formation of diamonds is possible because there are regions deep within the Earth that are at a high enough pressure and temperature that the formation of diamonds is thermodynamically favorable (see the diamond phase diagram and geotherms here). Under continental crust, diamonds form starting at depths of about 150 kilometers (90 miles), where pressure is roughly 5 gigapascals ...

Geology of the Capitol Reef area - Cutler Group. In early Permian time Utah was on a continental shelf that was occasionally covered by a shallow arm of the Panthalassa Ocean. That part of Laurasia was on a passive continental margin not unlike the current west coast of equatorial Africa. The resultant formations are part of the approximately 290 to 250 million year old Cutler Group. Utah was nearly on the paleoequator while the first formations of the Cutler Group were deposited but it had migrated nearly to 10Â ...

Geology of the Capitol Reef area - Glen Canyon Group. All three formations of the Glen Canyon Group were laid down in the Mid to Late Triassic during a time of increasing aridity. Slightly clockwise and northward movement of the North American Plate was bringing the area into a dryer climatic belt. The direction of cross-bedding in Glen Canyon Group sand dunes suggests that prevailing winds from the north transported the sand into the region. Outcrops of the Glen Canyon Group's three formations are the most promi ...
