Down to Earth With: Sally Jewell

Most people who find their way into public office start locally, perhaps by running for a seat on the school board or city council. Sally Jewell’s first foray into public service came at the behest of President Obama, who last year nominated her as the 51st Secretary of the Department of the Interior (DOI) — the first Secretary in more than a decade with a background in geoscience.

January 26, 1905: The world's largest gem-quality diamond is unearthed

Each day, thousands of visitors to the Smithsonian Institution's National Museum of Natural History view the rare and spectacular Hope Diamond, a 45-carat blue diamond. And dozens of diamonds bigger than the Hope — with names like Excelsior, Incomparable and Jubilee — have also been retrieved, cut and polished to perfection.

December 27, 1888: The Geological Society of America is founded

When the Geological Society of America (GSA) held its first organizational meeting in December 1888, there were only about 200 geologists in North America. Today, as GSA celebrates its 125th anniversary, the organization has evolved into one of the world’s largest societies devoted exclusively to geology, representing more than 25,000 members — researchers, students, teachers and industry professionals with interests spanning the geosciences — in 107 countries.

Mineral Resource of the Month: Phosphate Rock

As a mineral resource, “phosphate rock” is defined as unprocessed ore and processed concentrates that contain some form of apatite, a group of calcium phosphate minerals that is the primary source for phosphorus in phosphate fertilizers, which are vital to agriculture.

Down to Earth With: Past American Geosciences Institute Congressional Geoscience Fellows

The American Geosciences Institute’s (AGI) William L. Fisher Congressional Geoscience Fellowship provides an opportunity each year for a geoscientist to work in Washington, D.C., as a staff member in the office of a member of Congress or congressional committee. Since the fellowship program began in 1998, many fellows have used the skills and knowledge they acquired to launch careers at federal and state agencies, nongovernmental organizations and universities.

Mineral Resource of the Month: Thallium

Thallium, a grayish-white metal similar to tin in appearance, was discovered spectroscopically in 1861. Like lead, it is heavy yet soft, and can be cut easily with a knife. When exposed to air, thallium’s luster quickly tarnishes to a blue-gray color owing to the formation of a film of thallium oxide. Its concentration in Earth’s crust is estimated at 0.7 parts per million; mostly it is found in association with potassium minerals in clays, soils and granites, but in general it is not commercially recoverable from those sources. Manganese nodules, found on the ocean floor, also contain thallium.
