This is a view of the Mediano anticline, strata dipping to the left into the lake waters. This large-scale fold structure is a witness of ancient deformation associated with the rise of the Pyrenees in the middle Eocene, 45 Million years ago. Excellent exposure of rocks in this dry area allow today’s geologists to study

Volcano Mutnovsky Kamchatka, Russia. (Stock image) Credit: © Tatiana / Fotolia Geochemical fingerprinting links microscopic ash found on the bottom of a Svalbard lake to volcanic event happening 7000 years ago and 5000 km away. Eruptions are cataclysmic events that may impact people living far from their volcanic sources. Just think back to the summer

These are Ordovician-Silurian marine fossils from the museum of Tohoku University. Credit: Kunio Kaiho Researchers in the USA and Japan say they may have found the cause of the first mass extinction of life. There have been five mass extinctions since the divergent evolution of early animals 600 -450 million years ago. The cause of

Earth’s mantle information is shown.

The new findings suggest that the mantle does not flow ubiquitously, as has been previously thought — and that it is

Spherical bubbles preserved in 3.48 billion-year-old rocks in the Dresser Formation in the Pilbara Craton in Western Australia provide evidence for early life having lived in ancient hot springs on land.

Calcite crystals precipitated in response to microbial activity. Tweezers shown for scale. Size of crystals ~5 mm (height). Credit: Henrik Drake It is becoming more and more appreciated that a major part of the biologic activity is not going on at the ground surface, but is hidden underneath the soil down to depths of several

Zircon crystals as old as 4.4 billion years were found in sandstone at Jack Hills of Western Australia. Credit: Stuart Hay, ANU Scientists at The Australian National University (ANU) say the early Earth was likely to be barren, flat and almost entirely under water with a few small islands, following their analysis of tiny mineral

Conventional theory holds that all of the early Earth’s crustal ingredients were formed by volcanic activity. Now, however, earth scientists have put forth a theory with a novel twist: some of the chemical components of this material settled onto Earth’s early surface from the steamy atmosphere that prevailed at the time.
