Colossal volcanic eruptions like the kind that may have obliterated the dinosaurs more than 65 million years ago are caused ...

Diamonds are formed deep within the Earth’s upper mantle, and a phenomenon called kimberlites plays a crucial role in bringing them to the surface. Kimberlites are volcanic eruptions that bring ...

New research suggests that mysterious blobs deep within Earth could be the driving force behind deadly volcanic eruptions.

Diamonds erupt from the deep as supercontinents break up. Now you can listen to the "song" of these kimberlite eruptions. When you purchase through links on our site, we may earn an affiliate ...

Diamonds form deep in Earth's crust, approximately 93 miles (150 kilometers) down.They are brought up to the surface very quickly in eruptions called kimberlites. These kimberlites travel at ...

The results showed the eruptions of most kimberlite volcanoes occurred 20 to 30 million years after the tectonic breakup of Earth’s continents. Dr Thea Hincks, ...

Diamonds can gush to the surface in violent eruptions. These eruptions have baffled scientists as they happen more often after continents break up. A new study provides an explanation, and it ...

In the May 3 Nature, Head and volcanologist Lionel Wilson of Lancaster University in England describe a model of a kimberlite eruption that explains the resulting mix of diamonds, spherules, and ...

Earth’s “pillars of heat” in a global mantle convection model can be used to predict kimberlite eruptions. Credit: Ömer F. Bodur. Towards the centre of the pillars, mantle plumes rise much faster and ...

It also added a major clue: kimberlite eruptions tend to migrate gradually from the continental edges to the interiors over time at a rate that is uniform across the continents.

image: Kimberlite volcanoes, the primary source of diamonds, contain pelletal lapilli -- enigmatic magma-coated clasts. These are generated deep in the volcanic vent by a granulation process ...

Geologists are proposing a new model for explaining the eruption of diamond-bearing kimberlites in Northern Alberta. Skip to main content. Your source for the latest research news.
