Mineral Resource of the Month: Cultured Quartz Crystal

Cultured quartz crystal, also known as electronic-grade quartz crystal, is single-crystal quartz that has properties that make it uniquely useful in electronic circuits for precise filtration, frequency control and timing for consumer and military use. Common uses for cultured quartz crystal include aerospace hardware, commercial and military navigational instruments, computers, clocks, games, television receivers, toys and communications equipment like cell phones.

USGS finds giant gas hydrate deposits on North Slope

Buried beneath Alaska's North Slope are about 85.4 trillion cubic feet of technically recoverable natural gas hydrates, according to a new U.S. Geological Survey assessment. That would be a significant source of energy to add to the U.S. energy mix — enough natural gas to heat 100 million homes for 10 years, Secretary of the Interior Dirk Kempthorne announced Wednesday.

Mineral Resource of the Month: Graphite

Graphite, a grayish black opaque mineral with a metallic luster, is one of four forms of pure crystalline carbon (the others are carbon nanotubes, diamonds and fullerenes). It is one of the softest minerals and it exhibits perfect basal (one-plane) cleavage. Graphite is the most electrically and thermally conductive of the nonmetals, and it is chemically inert.

Mineral Resource of the Month: Antimony

Today, antimony is used in everything from flame retardants, batteries, ceramics and glass. About 40 percent of the primary antimony consumed in the United States goes into flame retardants, chemicals that when applied to or coated on a variety of materials (such as aircraft, automotive seat covers and children’s clothing and toys) make them more resistant to combustion. The remainder is used primarily in glass for television picture tubes and computer monitors, in pigments, in stabilizers and catalysts for plastics, and in ammunition, cable coverings, friction bearings, lead-acid batteries, pewter and solders.

Gustav and the rising waters

Right now, Hurricane Gustav is lashing the Gulf Coast with its Category-2 (177 kph/110-mph) winds. Around 11 a.m. this morning, the hurricane made landfall, slamming into the coast about 110 kilometers to the southwest of New Orleans instead of driving straight into the city.
