There are three types of rock found on Earth. These are igneous, metamorphic and sedimentary. Each rock type is formed in a different way. For example, the rock malachite is mostly made of the ...

Thundereggs look like regular rocks from the outside, but contain intricate and colorful mineral patterns inside — often made ...

Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the ...

Figure 1: Comparison of the whole-rock chemical compositions of the Idiwhaa tonalitic gneiss with Icelandic igneous rocks and Archaean TTGs. Figure 2: Zircon phase relations and correlated zircon U–Pb ...

If you’ve ever studied geography, looked at fossils in a museum, or even looked up at a craggy cliffside or a steep mountain, you’ll know that rocks usually take millions of years to form. However, ...

A rock commonly found in the southeast corner of the Arabian Peninsula could be used to soak up carbon dioxide and slow down global warming, scientists say. When carbon dioxide comes in contact with a ...

During the nearly 14 months that it has spent on the red planet, Curiosity, the Mars Science Laboratory (MSL) rover, has scooped soil, drilled rocks, and analyzed samples by exposing them to laser ...

This picture shows a very famous outcrop where nearly horizontal black and white layers are observed. The BIC made of layers of igneous rock in a basin shape, formed over a period of about 1 million ...

The first rock that scientists analyzed on Mars with a pair of chemical instruments aboard the Curiosity rover turned out to be a doozy -- a pyramid-shaped volcanic rock called a "mugearite" that is ...

The multi-coloured layers of banded iron formations could connect ancient changes on earth’s surface—like the emergence of photosynthetic life—to planetary processes like volcanism and plate tectonics ...

Scientists report on the analysis of a surprisingly Earth-like Martian rock, discovered by the Mars Science Laboratory rover Curiosity, that offers new insight into the history of Mars's interior and ...
