altered over time through geological processes, the Australian rocks have remained relatively unchanged since their inception 3.47 billion years ago. contains 16 protons and 16 neutrons in its nucleus ...

Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when ...

Organic debris slowly settles to the seabed, where it is consumed by microorganisms. Initially, some microbes use molecular oxygen to oxidize this organic matter, much like we do in the process of ...

For the first time, researchers have been able to show hard data that a large injection of sulfur impacted Earth's atmosphere after an asteroid strike caused the planet's mass dinosaur extinction 66 ...

A research team led by Prof. SHEN Yan'an from the University of Science and Technology of China (USTC) has made significant progress in studying the sources and formation mechanisms of haze. Through ...

Research shows that variations in pyrite sulfur isotopes may not represent the global processes that have made them such popular targets of analysis and interpretation. A new microanalysis approach ...

Strange gas signatures in some of Earth’s oldest rocks may have been produced in a different way than previously thought. When sulphur dioxide reacts with sunlight it creates sulphur and oxygen ...

A study utilizing ALMA observations of Io's atmosphere reveals a significant depletion of lighter sulfur isotopes, suggesting extensive and prolonged volcanic activity throughout its 4.57 billion-year ...

American geologist and astronaut Harrison Hagan Schmitt takes rock samples from the surface of the moon during America's last lunar landing mission of the 20th century, Apollo 17, December 1972.

The disappearance of mass-independent sulfur isotope fractionation (S-MIF) within the c. 2.3-billion-year-old (Ga) Rooihoogte Formation has been heralded as a chemostratigraphic marker of permanent ...
