Ancient source of oxygen for life hidden deep in the Earth’s crust — ScienceDaily

Scientists at Newcastle University have discovered a source of oxygen that may have influenced the evolution of life before the advent of photosynthesis. The pioneering research project, led by Newcastle University’s School of Natural and Environmental Sciences and published today in Nature Communications, uncovered a mechanism that can generate hydrogen peroxide from rocks during the … Read more

Huge, 170-carat pink diamond is window into Earth’s origins

A 170-carat pink diamond found in Angola may be the largest such stone to be unearthed in 300 years. “Only one in 10,000 diamonds is colored pink,” Stephen Wetherall, CEO of the Lucapa Diamond Company, told The Associated Press. “So you’re certainly looking at a very rare article when you find a very large pink … Read more

New paleomagnetic research suggests Earth’s solid inner core formed 550 million years ago and restored our planet’s magnetic field — ScienceDaily

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 invisible but is vital for life on Earth’s surface because it shields the planet from solar wind — streams of radiation from the sun. About 565 million years ago, however, the … Read more

Earth’s crust is dripping ‘like honey’ into its interior under the Andes

Earth’s crust is dripping “like honey” into our planet’s hot interior beneath the Andes mountains, scientists have discovered. By setting up a simple experiment in a sandbox and comparing the results to actual geological data, researchers have found compelling evidence that Earth’s crust has been “avalanched away” across hundreds of miles in the Andes after … Read more

The Earth’s crust has been ‘dripping’ beneath the Andes Mountains for millions of years: Researchers

Just like honey slowly dripping from a spoon, parts of the rocky outermost layer of Earth’s shell are continuously sinking into the more fluid layer of the planet’s mantle over the course of millions of years. Known as lithospheric dripping – named for the fragmentation of rocky material that makes up Earth’s crust and upper … Read more

Geoscientists confirm millions-year-old dripping of Earth’s crust beneath Andes Mountains

Just like honey slowly dripping from a spoon, parts of the rocky outermost layer of Earth’s shell are continuously sinking into the more fluid layer of the planet’s mantle over the course of millions of years. Known as lithospheric dripping – named for the fragmentation of rocky material that makes up Earth’s crust and upper … Read more

What a Martian meteorite can teach us about Earth’s origins — ScienceDaily

These days, not so much. But more than 4.5 billion years ago, it’s possible the Red Planet had a crust comparable to Iceland today. This discovery, hidden in the oldest Martian fragments found on Earth, could provide information about our planet that was lost over billions of years of geological movement and could help explain … Read more

New model shows Earth’s deep mantle was drier from the start — ScienceDaily

Earth’s mantle is the thick layer of silicate rock between Earth’s crust and its molten core, making up about 84% of our planet’s volume. The mantle is predominantly solid but, on geologic time scales, it behaves as a viscous fluid – as difficult to stir and mix as a pot of caramel. But, sticking with … Read more
