Peering Into the Earth’s Violent Past : New techniques see origin of ancient volcanic eruptions

Peering Into the Earth’s Violent Past : New techniques see origin of ancient volcanic eruptions

Tracing a 65 million year history of the Earth is no easy task, but researchers at the University of Quebec have found a new method. By taking a tango through time, they created a new tool for modeling our past Earth, and have used it to discover a second hotspot origin for the Deccan traps.

A Rocky Road to the Past: Scientists Discover Trends in Long-Term Climate Change

Using new analytics to understand tiny mineral crystals, a Yale G&G team has discovered evidence for the effect of volcanic activities on global climate. Because the zircon crystals that were investigated have a particularly long lifetime, this innovative technique carries potential for the future of climate change research.

Bridging the Depths of the Earth with its Surface

Bridging the Depths of the Earth with its Surface

“Bridgmanite” is hardly a household name. And yet, bridgmanite is likely the most abundant mineral on Earth, composing much of the mantle, the thickest layer of our planet. This mineral may provide clues into how the solid Earth—and its atmosphere—has evolved over its long history.

Adolescent Crisis, Stable Maturity: The Life Story of Earth’s Magnetic Field

Most of us are familiar with the Earth’s magnetic field as the invisible force directing our compasses to the north. But if you took a time machine back 800,000 years and followed the red needle, your compass would send you
