This is a sample of rutile, one of the primary mineral sources of titanium. While as a metal, titanium is well known for corrosion resistance and for its high strength-to-weight ratio, approximately 95% of titanium is consumed in the form of titanium dioxide (TiO2), a white pigment used in paints, paper, and plastics.

A sample of azurite, the blue mineral, and malachite, the green mineral. Both azurite and malachite are copper minerals that were once used as pigments but are now mostly valued as collectors minerals. They do serve as good indicators of copper deposits that can be developed.

These two minerals are apophyllite and prehnite. Both apophyllite, the clear crystals, and prehnite, the green mineral, are primarily prized as collectors minerals.
Sample provided by Carlin Green, USGS. Sample originated from Virginia Crushed Stone Quarry, Virginia, and is 4.6cm in size.

This sample is clinozoisite, a calcium aluminum silicate mineral. It is mostly prized as a collectors mineral rather than a source of its industrial mineral commodities.
Sample provided by Carlin Green, USGS. Sample originated from Hachupa, Pakistan, and is 6.0cm in size.

Pyrrhotite is an iron sulfide mineral related to iron pyrite, which is one of the minerals known as Fool's Gold. Pyrrhotite, although not one of the Fool's Gold minerals, is sometimes called magnetic pyrite as it is weakly magnetic. It is most valued as a collectors mineral.

The quality of the water we drink can potentially impact our health. The USGS has several programs and cooperative projects that characterize the quality of selected rivers and aquifers used as sources of drinking water to community water systems in the United States.

Researchers survey Elwha River elevation and depths. Clockwise from upper left: setting up a traditional survey instrument above the river; measuring river depths from a kayak with sonar and GPS; walking the beach with GPS backpacks; and determining offshore depths using a personal watercraft with GPS and sonar.

This sample is of the mineral cerussite, once an important source of lead for paints and pigments. With the phasing out of lead-based paints, cerussite is now mostly valued as a collectors mineral.
Sample provided by Carlin Green, USGS. Sample originated from Mibladen, Morocco, and is 5.6cm in size.
