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.

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.

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.

USGS scientist Sara Zeigler records habitat characteristics in iPlover at an ‘exclosed’ nest. On some beaches, managers erect netting around nests to protect eggs/chicks and adults from predators, allowing movement of chicks and parents to and from the nest but excluding predators

Groundwater data were collected in the spring and fall of 2008 from three sites representing different geological settings and biogeochemical conditions within the surficial glacial aquifer of Long Island, NY.

Map showing the surficial geology of Vineyard and western Nantucket Sounds with equivalent onshore geology (adapted from Stone and DiGiacomo-Cohen, 2009). The areal extents over which offshore subsurface geologic units crop out at the sea floor were interpreted from seismic-reflection data.

USGS Research Geologist Jessica Rodysill and USGS-NAGT Student Intern Kristen Steele inspect a sediment core from Bearsden Pond near the Fredericks Hall fault, one of three subsidiary faults that broke in response to slip along the main Quail fault on 23 August 2011 during the M5.8 earthquake.  This research is a collaborative project between the USGS Land Use

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.
