The Geological Past Behind Today’s Clean Energy Materials
Ancient plate collisions billions of years ago are now understood to be the key to locating rare earth element deposits. New geological models reveal these elements concentrate above mantle zones enriched by past subduction. This groundbreaking d...
The presence of mountain ranges and broken terrain is a reflection of tectonic events that took place long ago; however, the implications of such structures go far beyond what can be seen on the surface. In the deepest layers of Earth’s crust, activities that took place billions of years ago affect the distribution of precious metals today.
According to recent studies published by Science Advances, rare earth element reserves are directly connected with ancient zones of plate convergence, where two plates would collide, and one would be forced to subduct under the other. Fluids and materials from such collisions penetrated into the Earth’s mantle, resulting in its enrichment.
Can we map the legacy of tectonic processes?
The developments in the field of geological modeling have made it possible for researchers to trace tectonic activity over the past two billion years.
IMG According to various research studies, a majority of rare earths are found above the areas where the mantle was already enriched before. This discovery refutes the previous understanding regarding mantle plumes, which had been the center of attention in all theories. It introduces a new approach to considering several stages of geological development. In addition, it is important to note that the interplay of subduction and subsequent melting processes is responsible for depositing minerals at economically viable sites.
Resources can be discovered by using a new method
Knowing how tectonic history relates to mineral formation has numerous benefits. For instance, by determining places with a history of subduction, geologists are able to pinpoint locations with greater possibilities of having rare earth deposits.
In turn, this increases efficiency in the search and minimizes risks due to uncertainties involved. It has been noted that rare earths are highly important in creating renewable energy systems and other technological gadgets like phones, making the process even more relevant. Geology on Earth not only records changes but also helps in determining valuable locations today.
