Oldest ice core ever drilled outside the polar regions

The oldest ice core ever drilled outside the polar regions may contain ice that formed during the Stone Age -- more than 600,000 years...

New research improves understanding of ancient landscapes

Geologists use zircon mineral grains to reconstruct what the Earth and its landscapes looked like in ancient times. These microscopic grains, commonly the width...

Unique underwater stalactites

In recent years, researchers have identified a small group of stalactites that appear to have calcified underwater instead of in a dry cave. The...

What Is Sea Glass?

What Is Sea Glass? Sea glass and beach glass are similar but come from two different types of water. "Sea glass" is physically and chemically...

What are Ripple Marks?

Ripple marks are sedimentary structures and indicate agitation by water (current or waves) or wind. Ripple marks are ridges of sediment that form in response...

Determining when humans started impacting the planet on a large scale

Humans have so profoundly altered Earth that, some scientists argue, our current geologic epoch requires a new name: the Anthropocene. But defining the precise...

What is Plate Tectonic?

Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates...

Scientists determine source of world’s largest mud eruption

On May 29, 2006, mud started erupting from several sites on the Indonesian island of Java. Boiling mud, water, rocks and gas poured from...

What are the three main types of faults?

What is a fault? A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative...

What Is a Geologic Fault?

A fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement as a result of...

Formation of coal almost turned our planet into a snowball

While burning coal today causes Earth to overheat, about 300 million years ago the formation of that same coal brought our planet close to...

Tidal and mangrove deposits during the Oligo-Miocene in the South China...

A study on 22–18 million-year-old tidal deposits reveals insights on the significance of mangrove organic carbon sequestration in the South China Sea at geological...

Challenging prevailing theory about how deep-sea vents are colonized

An article just published in the Proceedings of the Royal Society B describes two remarkably different hydrothermal vent fields discovered in the southern Gulf...

Stripy cliffs in Segelsällskarpet Fjord, Northeast Greenland National Park

Sparkling springs aid quest for underground heat energy sources

Analysis of natural sparkling mineral water has given scientists valuable clues on how to locate hot water springs -- potential sources of sustainable, clean...

Hundred-year-old law on fluid flow overturned by new research

Engineers from Imperial College London have dispelled a 100-year-old scientific law used to describe how fluid flows through rocks. The discovery by researchers from Imperial...
