The mineralogy of Earth is determined by its chemical composition, its physical conditions, and its evolution over time. About 5,000 minerals have been found on Earth and every year some new ones are ...

Today 5,000 to 7,000 minerals are formally recognized on earth and every year some new ones are discovered. Most were hidden in rocks for million years, found only at a few sites or small crystals and ...

Minerals are geologic time capsules of the environments in which they form. With the right approach, their mysteries can be cracked open to reveal key features of the ancient Earth or other planets.

Interactions between iron, water, oxygen and ions quickly become complex. MTU scientists developed a more precise method to observe how iron minerals like rust form. One can easily see with the naked ...

The impact of Earth’s geology on life is easy to see, with organisms adapting to environments as different as deserts, mountains, forests, and oceans. The full impact of life on geology, however, can ...

To prepare for this lab, you should review the background information about the three rock types on p.52-58. You already should know something about igneous and sedimentary rocks from last week. This ...

Iron in the ground has quietly been doing climate work for centuries, binding carbon in soils so effectively that it can stay ...

Researchers say they are one step closer to finding out if life ever existed on Mars. An international team has found “compelling evidence” of multiple mineral-forming events just below the planet’s ...

Like many abandoned mines, the Eureka uranium mine in northern Spain is a maze of long, dank tunnels. Water seeping down the walls carries dissolved substances that percolated through rocks overhead.
