Washington DC: Scientists have revealed that diamonds could disclose the process of how a floating section of the mantle under some of the continents became thick to provide long-term stability. The research was published in the journal Science.

"We have found a way to use traces of sulfur from ancient volcanoes that made its way into the mantle and eventually into diamonds to provide evidence for one particular process of continent building," explained Karen Smit, lead author of the study.
