Studying ancient ocean floors could help discover the minerals needed to produce electric cars and solar panels.

Researchers at the University of Queensland led a collaborative study that examined ocean floor remnants in eastern Australia and Central Asia and applied a method to determine the age of the calcite trapped inside.

Dr Renji Chu from the University of Queensland’s School of Earth and Environmental Sciences said the findings could make it easier to source critical minerals Used in renewable and clean technologies.

“Calcite and other hydrothermal minerals are often observed in critical mineral deposits and form under the activities of mineralizing fluids,” said Dr. Zhou.

“Our work shows that we can trace the history of fluids in the Earth’s crust and learn when and what mineral resources they might generate.”

The renewable energy sector continues to grow rapidly with increasing demand for technologies such as wind turbinesSolar panels, electric vehicles and batteries.

“These often require large amounts of important minerals,” he said.

“Electric cars need up to four times more copper than conventional cars, and a single wind turbine uses several tons of permanent magnets made from rare earth metals.”

Dr. Zhou said the ability to study and discover these minerals will become increasingly important.

“Researchers at several institutions are doing an excellent job in this area, including the University of Queensland Center for Geoanalytical Mass Spectrometry,” said Dr. Chu.

“Our hope is to expand our collaboration with industry and academia to increase understanding and discovery of important minerals in the future.”

This research was published in Chronological geology, Earth communication and the environment.
