Unearthing Earth's Evolution through Ancient Diamonds

Analysis of ancient diamonds formed between 650 and 450 million years ago has revealed new insights into the processes of continent formation and movement during the early evolution of complex life on Earth. These superdeep diamonds, found in Brazil and Western Africa, provide a window into the deep plate tectonic engine and the supercontinent cycle. By dating the inclusions inside the diamonds, researchers discovered a previously unknown geologic process and traced the growth of the supercontinent Gondwana. The diamonds, along with their host rocks, were transported to the base of Gondwana, and later brought to the surface through volcanic eruptions. This research sheds light on the evolution of Earth's continents and their role in the development of life.
