The ancient history of Earth has always been hard to read. Most of the planet’s earliest crust has been lost, buried, or melted by geologic processes over billions of years. The rare remnants that ...

Nickel (Ni) and cobalt (Co) are critical elements for modern technologies, with high-grade Ni and Co ores becoming ...

Earth formed about 4.6 billion years ago, during the geological eon known as the Hadean. The name "Hadean" comes from the ...

The rocks at the surface of the modern Earth are broadly divided into two types: felsic and mafic. Felsic rocks are generally relatively low density — for a rock — and light in colour because ...

Interactions of mantles at different depths.Molybdenum isotopes in mafic igneous rocks record slab-mantle interactions from subarc to postarc depths (IMAGE) University of Science and Technology of ...

We are exploring the geodynamics of mafic and ultramafic rock complexes in southern Mexico and the economic potential for their exploitation. This multi-disciplinary project involves: detailed ...

Scientists believe that the primitive crust largely comprised dark, silica-poor mafic rocks, so there has been a question over how the Acasta River felsic rocks could have formed.

Some of the Earth’s oldest rocks may have formed from the high temperatures of meteorite impacts, a new study reports. Granite-like, or felsic, rocks in northwest Canada dating back to the Earth ...

Scientists now think early Earth contained light-colored rocks, like the granite within Yosemite’s Half Dome. Such rocks likely formed via plate tectonics.

Formed in 2012, Ontario-based Mafic Inc. produces composite fibers made from basalt rock, which is formed by the rapid cooling and solidification of lava exposed to the earth’s surface. The ...

The titanium timeline suggests that the primary trigger of the surge of phosphorus was the change in the makeup of mafic rock over time.
