Understanding how gold forms is crucial for knowing where to find it and how to extract it sustainably. McGill researchers have answered a long-standing question in geology that could lead to new ore discoveries. Researchers traveled to...
Earth system models (ESMs) help us understand climate and environmental changes. With advances in computing power, ESMs can now be run at kilometer-scale (k-scale) resolutions, capturing very fine details to better predict extreme weather and understand...

Researchers uncover source rocks of the first real continents

Geoscientists have uncovered a missing link in the enigmatic story of how the continents developed—a revised origin story that doesn't require the start of...

New technique enhances imaging of fluid-filled rocks, finds connection to microearthquakes

An international team of scientists led by Dr. Xin Liu, Assistant Professor of the Department of Earth Sciences, The University of Hong Kong (HKU),...

Asteroid rocks may hold secrets to the origin of the solar system

Early Sunday morning, NASA's OSIRIS-REx spacecraft released a container that subsequently landed in Utah containing material from Bennu, a carbon-rich asteroid in the solar...

Iron-rich rocks unlock new insights into Earth’s planetary history

Visually striking layers of burnt orange, yellow, silver, brown and blue-tinged black are characteristic of banded iron formations, sedimentary rocks that may have prompted...

In-situ observations of marine sedimentary rocks suggest ancient northern ocean on Mars

An international research team led by Professor Long Xiao from the School of Earth Sciences of China University of Geosciences (Wuhan) has discovered the...

Scientists make ‘disturbing’ find on remote island: plastic rocks

There are few places on Earth as isolated as Trindade island, a volcanic outcrop a three- to four-day boat trip off the coast of...

Why are most rocks on Earth much younger than the planet itself?

The rocks on Earth are not all the same age. In fact, most are significantly younger than the planet itself. The oldest sections of...

Possible organic compounds found in Mars crater rocks

A study published in Science analyses multiple rocks found at the bottom of Jezero Crater on Mars, where the Perseverance rover landed in 2020,...

How did Earth avoid a Mars-like fate? Ancient rocks hold clues

Approximately 1,800 miles beneath our feet, swirling liquid iron in the Earth's outer core generates our planet's protective magnetic field. This magnetic field is...

Rocks unravel the secrets of the Earth’s magnetic field

More than 350 million years ago something odd was going on with the Earth's magnetic field. Scientists now propose that the field was really...

Grain size of rocks in Earth’s mantle affects tectonics

The planet is shaped by forces deep within its interior. These push the plates of the Earth's crust against each other, causing mountains and...

Researchers discover Archean continental rocks at the Southwest Indian Ridge

In between Earth's rigid tectonic plates above and its convecting mantle below is a hot and soft layer known as the asthenosphere. At mid-ocean...
