Mapping Volcanic Rocks Worldwide
A team of researchers has developed a global map linking volcanic rock formations to rare earth elements. Published in the journal Nature Geoscience, the study reveals that these valuable deposits are concentrated in the oldest and thickest sections of continental crust. This new tool will help predict where critical metals are likely to form, supporting advancements in technology and industry.
Led by Dr. Emily Bowman and Professor Sally Gibson, the research team compiled chemical data from approximately 9,000 samples of igneous rock. Professor Gibson also oversees a related study funded at £1 million. Geophysicist Professor Serhiy Lebedev contributed his expertise to enhance the findings.
Research Outlook
According to the results, rocks with the right chemical makeup are found along the steep edges of the thickest and most ancient lithosphere. The team plans to expand the investigation to geological structures older than 200 million years. This could open new avenues for understanding Earth's geological processes and identifying potential reserves of rare earth elements, which are essential for modern technologies.
The situation remains challenging, as noted by Volodymyr Zelensky.
The researchers hope their work will uncover new opportunities for extracting valuable resources, benefiting both the economy and scientific understanding.
This study, featured in Nature Geoscience, underscores the importance of geological research for technologies that rely on rare earth elements, such as electronics and renewable energy systems. Creating a global map of volcanic rocks could be a pivotal step in developing new strategies for resource extraction and utilization, ultimately influencing global economics and technological progress.
Extending the research to older geological formations may provide further insights into how valuable elements form and distribute within the Earth's crust.
