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 ...

Introduction -- Physical properties of magma -- Intrusion of magma -- Forms of igneous bodies -- Cooling of igneous bodies and other diffusion processes -- Classification of igneous rocks -- ...

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 ...

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 ...

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 ...

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 ...

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 ...

Rock is a solid mass of minerals that have joined together over time. Geology is the study of how the Earth is formed and the things that happen to the Earth. As part of this, geologists study rocks ...
