Scientists have shown how the freezing of a ‘slushy’ ocean of magma may be responsible for the composition of the Moon’s crust.
Scientists from the University of Cambridge and the Ecole normale supérieure de Lyon, have proposed a new model of crystallisation where crystals remained suspended in liquid magma over hundreds of millions of years as the lunar ‘slush’ froze and solidified.
Study pinpoints timing of Chicxulub asteroid impact
Groundbreaking study confirms time of year when asteroid wiped out dinosaurs and 75 percent of life on Earth.

“Volcanic winter” likely contributed to ecological catastrophe 250 million years ago
A team of scientists has identified an additional force that likely contributed to a mass extinction event 250 million years ago.
The world’s oldest mercury poisoning revealed in Copper Age Iberia
A recent paper published in the International Journal of Osteoarchaeology and in which researchers from the University of Seville participate, explores the complex relationship between humans and mercury over time.
Researchers present evidence that a cosmic impact destroyed a biblical city in the Jordan Valley
In the Middle Bronze Age (about 3600 years ago or roughly 1650 BCE), the city of Tall el-Hammam was ascendant.
Extreme volcanism did not cause the massive extinction of species in the late Cretaceous
A study published in the journal Geology rules out that extreme volcanic episodes had any influence on the massive extinction of species in the late Cretaceous.
Pictograms are first written accounts of earthquakes in pre-Hispanic Mexico
The Codex Telleriano Remensis, created in the 16th century in Mexico, depicts earthquakes in pictograms that are the first written evidence of earthquakes in the Americas in pre-Hispanic times, according to a pair of researchers who have systematically studied the country’s historical earthquakes.
Ancient meteorite found in England could reveal the origins of life on Earth
A 4.6-billion-year-old meteorite found in a field in Gloucestershire, England, is likely a remnant of cosmic debris left over from the birth of the solar system and could answer questions about how life began on Earth.
Comet strike may have sparked key shift in human civilization
A cluster of comet fragments believed to have hit Earth nearly 13,000 years ago may have shaped the origins of human civilisation, research suggests.
The ‘Great Dying’
The Paleozoic era culminated 251.9 million years ago in the most severe mass extinction recorded in the geologic record.
New research uncovers continental crust emerged 500 million years earlier than thought
The first emergence and persistence of continental crust on Earth during the Archaean (4 billion to 2.5 billion years ago) has important implications for plate tectonics, ocean chemistry, and biological evolution, and it happened about half a billion years earlier than previously thought, according to new research being presented at the EGU General Assembly 2021.
Human land use wasn’t always at nature’s expense
Nearly three-quarters of Earth's land had been transformed by humans by 10,000 BC, but new research shows it largely wasn't at the expense of the natural world.
Lightning Strikes Played a Vital Role in Life’s Origins on Earth
Lightning strikes were just as important as meteorites in creating the perfect conditions for life to emerge on Earth, geologists say.
Organic Molecules Found in 3.5 Billion-Year-Old Rocks
A research team including the geobiologist Dr. Helge Missbach from the University of Cologne has detected organic molecules and gases trapped in 3.5 billion-year-old rocks.
Study Shows Tasmanian Aboriginals Witnessed the Laschamp Geomagnetic Excursion.
Drilling a 270,000-year old core from a Tasmanian lake has provided the first Australian record of a major global event where the Earth's magnetic field 'switched '- and the opportunity to establish a precedent for developing new paleomagnetic dating tools for Australian archaeology and paleosciences.
