A collaborative team of scientists has discovered that life on Earth over three billion years ago relied on the metal molybdenum, which was incredibly scarce in the environment at the time. The study, ...

Earth exhibits a distinct bimodal distribution of continental and oceanic crust, a feature that differentiates it from other terrestrial planets in the solar system (Dilek and Polat, 2008; Dhuime et ...

The Nuvvuagittuq Supracrustal belt in northern Quebec is a rare similar to 9 km(2) fragment of the Earth's early crust. The belt contains a metamorphosed volcano-sedimentary sequence that is at least ...

The Eoarchean (>3.65 Ga) quartz-pyroxene rock from Akilia, Greenland, represents a key fragment of Earth’s earliest rock record. By integrating novel potassium isotope data with petrological ...

“Our study focuses on chemical sedimentary rocks found in the Saglek-Hebron. These rocks, among the oldest on Earth, dating back 3.9 billion years, are created through oceanic precipitation,” said ...

The isotopic composition of carbon in iron formations from the Saglek-Hebron Complex in Nunatsiavut (northern Labrador) has been seen as evidence of the earliest traces of life on Earth. But a new ...

Sketch of an outcrop (site 8A/A) in banded iron formation (BIF) intruded by mafic dykes shows the overprinted (baked) and not overprinted (unbacked) magnetite. A to D explain in schematic cartoons how ...

Magnetic fields make life possible on Earth by protecting the planet from the Sun's harmful cosmic rays. A new study found the oldest evidence yet of this field’s existence in iron-rich rocks in ...

A group of scientists finds the oldest signal of the planet’s magnetic field in the the Isua Greenstone Belt in Greenland In southwest Greenland, surrounded by ancient ice, lies the Isua Greenstone ...
