A ∼1.6 Ga accretionary event in the polymetamorphic Lesser Himalaya, India: Insights into late-stage assembly of the Columbia supercontinent A series of collisions among most of the continental fragments between 2.1 Ga and 1.8 Ga culminated in the assembly of the Columbia supercontinent. Ve…

New paper alert!

I have always wanted to work in old rocks and my Indian colleagues, especially my good friend Biraja, made that possible!

Colour illustration of rock formations with wheat growing on them, entitled 'View in the Great Chasm of Axmouth Landslip.' Looking Westward. Reaping the Wheat 25th August 1840.' The illustration includes depictions of people in 19th century clothing.

This beautiful colour plate shows rock formations on the East Devon coast caused by landslips between December 1839 & February 1840. Corn grew on the rocks that had fallen from the fields above, attracting fascinated visitors.

AI Is Inventing Academic Papers That Don't Exist -- And They're Being Cited in Real Journals Academic articles from authors using large language model are creating an ecosystem of fake research that threatens human knowledge itself.

Do not cite an academic paper unless you’ve read it

It's Trilobite Tuesday! The Devonian trilobites that emerge from outcrops aligning Bolivia's sky-high Altiplano plateau, like this Belenopyge, rank among the most difficult-to-obtain trilobites in the world—mostly because they're located more than 11,500 ft (3,505 m) up in the Andes Mountains.

Rotations took place between 66 and 55 million years ago, and after the main folding event that shaped the range. Although the exact tectonic mechanism remains unclear, we suggest that subduction in eastern Mexico played the key role in driving the bending of the Sierra Madre Oriental.

We analyzed the magnetic signal preserved in the rocks together with fracture patterns in 25 folded structures.

Our results show that the mountain belt rotated almost 90° to the left (counterclockwise) in the northern part of the orocline and about 30° to the right (clockwise) in the southern part.

Curves of this kind are known as oroclines. The exact timing and the process that created the orocline in northeast Mexico remain uncertain, with previous estimates ranging from 120 to 50 million years ago. To better understand its formation, we studied Cretaceous rocks across this curved region.

The Sierra Madre Oriental in Mexico is a curved mountain range formed as a result of the subduction of the Pacific Ocean plates beneath North America.

Its curve, about 100° wide and opening to the southwest, developed after the mountains were already built.
