Geologists reveal ancient connection between England and France

The British mainland was formed from the collision of not two, but three ancient continental land masses, according to new research. Scientists have for centuries believed that England, Wales and Scotland were created by the merger of Avalonia and Laurentia more than 400 million years ago. However, geologists based at the University of Plymouth now […]

Global warming: Worrying lessons from the past

Fifty-six million years ago, Earth experienced an exceptional episode of global warming. In a very short time on a geological scale, within 10,000 to 20,000 years, the average temperature increased by 5 to 8 degrees, only returning to its original level a few hundred thousand years later. Based on the analysis of sediments from the […]

Geology, biology agree on Pangaea supercontinent breakup dates

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Scientists at The Australian National University (ANU) have found that independent estimates from geology and biology agree on the timing of the breakup of the Pangaea supercontinent into today’s continents. When continents break up, single species are divided into two and drift apart — physically and genetically. Lead […]

Pockmarks :Linking Geology and Microbiology

Linking Geology and Microbiology: Inactive Pockmarks Affect Sediment Microbial Community Structure Pockmarks are geological features that are found on the bottom of lakes and oceans all over the globe. Some are active, seeping oil or methane, while others are inactive. Active pockmarks are well studied since they harbor specialized microbial communities that proliferate on the […]
