Geologists have been baffled by perforations in an Australian quartzite (rock), identical in shape to burrows made in sands by crustaceans; the original sandy sediment is a billion years older than the oldest known animals. An international team of scientists has now resolved the mystery.

Geologists completed research characterizing the complex geological evolution of the Orphan Basin, offshore Newfoundland and Labrador, using an extensive database of newly available, modern 2D and 3D broadband seismic reflection data. These data allow geologists to visualize and understand the subsurface.

Using a new mechanistic model of evolution on Earth, researchers can now better explain why the rainforests of Africa are home to fewer species than the tropical forests of South America and Southeast Asia. The key to high species diversity lies in how dynamically the continents have evolved over time.

The continents, a specific feature of our planet, still hold many secrets. Using chemical data on sedimentary rocks compiled from the scientific literature from the 1980s to the present day, researchers have uncovered a new geological history of the continents. The research shows that their growth was not a continuous process, and that they have … Continental growth is not a continuous process

Researchers have demonstrated how a detailed ‘cradle to grave’ evaluation at the outset of new metal mining explorations can greatly mitigate against negative environmental impacts.

Rift Valley lakes within eastern Africa range from freshwater to highly alkaline systems and are homes to diverse ecosystems. These Rift Valley lakes are also sedimentary repositories, yielding a high-resolution environmental record that can be targeted to better understand the environmental and climatic context of human evolution over the past few million years in eastern … Records from Lake Magadi, Kenya, suggest environmental variability driven by changes in Earth’s orbit

Lava samples have revealed a new truth about the geological make-up of the Earth’s crust and could have implications for volcanic eruption early warning systems, a new study has found.

Greenland may be best known for its enormous continental scale ice sheet that soars up to 3,000 meters above sea level, whose rapid melting is a leading contributor to global sea level rise. But surrounding this massive ice sheet, which covers 79% of the world’s largest island, is Greenland’s rugged coastline dotted with ice capped … A recent reversal in the response of western Greenland’s ice caps to climate change

Scientists have studied an ancient supervolcano in Indonesia and found such volcanoes remain active and hazardous for thousands of years after a super-eruption, prompting the need for a rethink of how these potentially catastrophic events are predicted.
