Understanding Earth's Early Mantle

Understanding the geologic history of Earth will no doubt be a decades, if not centuries long process, as we gather more and more data and expand our knowledge. New research published in the April 25 issue of the journal Nature has contributed an interesting new data point, however, shining a light on the processes involved in

Computer Model Shows How Deep Underwater Carbon Could Resurface

Understanding the carbon cycle is a vital part of understanding how our planet will react to a continually warming planet, especially because that warming is caused by increasingly high levels of carbon dioxide in the atmosphere. One tantalisingly elusive aspect of the carbon cycle is the carbon stored deep in the Earth’s mantle. “We are

Magma Forms Deeper than Previously Thought

New research results from a team led by geologist Rajdeep Dasgupta of Rice University have shown that magma forms much deeper than geologists had previously thought. The scientists put minute samples of peridotite – a rock derived from Earth’s mantle – under very high pressures in a laboratory and found that the rock can and does liquify
