The study, published in Nature Communications, found that Cerium, which belongs to the group of elements called 'rare earths' speeds up important reactions and plays other significant roles.
The research team discovered that Cerium plays an active role during the replacement of magnetite by hematite: it acts as a catalyst that speeds up the reaction; provides space for the precipitation of the value minerals; and promotes a positive feedback between reaction and fluid-flow, that contributes to increasing the metal endowment of the deposit.The study potentially has wide implications for the materials sector and industry.
The study establishes the fact that trace elements can have an important, yet difficult to predict, effect on the coupling between fluid flow, creation of porosity, and mineral dissolution and precipitation, that controls large-scale element mobility and rheology in the Earth's crust.
