Diamond Reveals Earth's Mantle Secret

According to a study published on Phys.org Earth Sciences, a team of Brazilian researchers has made a groundbreaking discovery, finding evidence of the mineral goethite inside a 3-millimeter diamond. Goethite, responsible for the brown color of soils, forms in the presence of water and incorporates water molecules into its structure. This finding suggests that goethite may transport and release water into the lower mantle, a region deep within the Earth's interior. This breakthrough has significant implications for our understanding of the Earth's water cycle and the role of minerals in transporting water to the planet's interior. The discovery highlights the importance of continued research into the Earth's geology and the potential for new insights into the formation and movement of minerals.
