British scientists plan to obtain a sample of mantle which is located between the crust and core of our planet. This type of venture was never done before and it could trigger a massive earthquake. Scientists from Cardiff University are behind the mission, which hopes to bring the first-ever samples of mantle – the rocky substance that makes up most of our planet between the crust and core – back to the surface to be studied. Professor Chris MacLeod, project co-leader, wants to investigate an area at the edge of the crust and mantle called the Moho boundary.It is a place where the seismic waves of earthquakes suddenly change speed. The area in question is called Atlantis Bank on the South West Indian Ridge of the Indian Ocean. It was chosen because faults and erosion have already thinned the crust there. The International Ocean Discovery Program (IODP) project could allow scientists to examine for the first time untouched peridotite from the mantle a rock, rich in olivine minerals
