A temperature jump of 400°C at a depth of 2 km—it’s possible in Krafla to cook a steak!
This study explains the heat transfer between a magma reservoir and the surrounding rock in the high-enthalpy geothermal exploration area of Krafla, Iceland. Thermomechanical numerical models explain the sudden jump […]

Climate warning for archaeological sites
From the Chauvet cave to the Ile d’Yeu, prehistoric sites are under close surveillance. The hope: to understand how climate change threatens them. And prevent the disappearance of cave paintings. […]

The origins of continents: continental crust shaped by water
ow did continents appear on Earth? This question, crucial to understanding the emergence of civilizations and life itself, remains one of the great mysteries of the early stages of planetary […]
Scientific result
Oxygen oases in the oceans 500 million years before oxygenation of the atmosphere
2.9-billion-year-old marine sedimentary rocks from Canada’s Red Lake region reveal areas of oxygen accumulation at a time when the oceans were globally anoxic and iron-rich. These oxygen oases played a […]

Assessing air quality with plants: yes, but for which elements?
Epiphytic plants, which absorb their nutrients exclusively from the air, are good indicators of the chemical composition of atmospheric particles and are often used in the literature as diagnostic tools. […]

Understanding the formation of iron-rich banded rocks
Until now, scientists have considered the absence of microfossils and the low level of organic carbon in banded iron formations, deposited between 2 and 3 billion years ago, to be […]

Deep long-period earthquakes discovered beneath Massif Central volcanoes
A recent study, published in Geophysical Research Letters, reveals atypical seismic signals beneath the volcanoes of the Massif Central. These signals, combined with the active presence of magma at depth, […]

How can uranium isotopes help trace the history of the Earth’s oxygenation?
A recent study reveals the existence of a uranium isotopic signature specific to oxygen-depleted environments. This discovery could help to better understand the history of the co-evolution between animal life […]
