Parameters considered in models for shoreline change, barrier island characteristics, and piping plover habitat availability. Together, these three models allow for forecasts of most likely future barrier island characteristics and piping plover habitat availability given sea-level rise.

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 augelite and quartz. Augelite is an aluminum phosphate mineral, primarily prized for collecting rather than as a source for its industrial mineral components.

Sample provided by Carlin Green, USGS. Sample originated from Mundo Nuevo Mine, Peru, and is 3.7cm in size.

This is a sample of axinite with iron, making it ferroaxinite. Axinite is primarily used as a collectors mineral.

Sample provided by Carlin Green, USGS. Sample originated from Puiva Mount, Russia, and is 3.0cm 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.

Torbernite is a copper phosphate mineral that contains uranium, making it somewhat radioactive. Although it can be used as a uranium ore, it's more valued as a collectors mineral. It can be used as a good indicator of uranium deposits, however.

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.

Large layered nodule from the Roadside pit, Spor Mountain, Utah, showing fluorite, opal, and bertrandite mineralization. Beryllium is concentrated in the outer opal-fluorite zone; such samples can contain as much as 1-percent beryllium as bertrandite.
