To trace how crucial ingredients for life arrived at Earth, scientists track noble gases. Now, improved methods are drawing new clues from krypton, the most cryptic of noble gases.
Extended periods of volcanism known as flood basalt eruptions lead to volcanic winters, which are often followed by an extended period of warming. But it was more than just carbon dioxide that warmed the globe.
The flooding that carved eastern Washington State 20,000 to 12,000 years ago could have been 80% smaller than the canyons’ volume today.
The geochemistry of basalt millstones and mixers from the city of Volubilis suggests a local origin—and that rocks were picked for specific purposes, from crushing olives to mixing dough.
The algorithm RevPET automatically reverses the complex multi-phase fractional crystallization path of oceanic basalts and offers new perspectives for advancing mantle thermobarometry.
Slow earthquakes beneath the accretionary prism updip from the locked portion of a subduction zone can be caused by basaltic blocks embedded in a shale matrix.
Scientists have shown that mineral carbonation can permanently capture and store carbon quickly enough and safely enough to rise to the challenge of climate change.
Scientists find evidence that a 50-meter-deep pit on the Moon's surface could be a skylight opening to an intact lava tube tens of kilometers long.
Isotopic signatures in volcanic basalts show that Earth's interior is even less uniform than scientists previously thought.
Drilling into the Rangitoto Island Volcano in the Auckland Volcanic Field in New Zealand offers insight into a small monogenetic volcano, and may improve understanding of future hazards.
