A new study has used X-rays to show that some rocks have a super-fluid past. The research, published in the journal Nature Communications, has important implications for understanding the formation of mineral deposits that are vital for batteries.
Superfluids are liquids that have no viscosity. This means that they can flow without any resistance, and they can even flow through solid objects. In the case of rocks, super-fluidity is thought to occur when the rocks are subjected to extremely high temperatures and pressures.
The new study used X-rays to analyse the structure of rocks that had been exposed to high temperatures and pressures. The X-rays showed that these rocks contained tiny pockets of super-fluid water. These pockets were located in the spaces between the mineral grains in the rocks.
The researchers believe that the super-fluid water was able to dissolve minerals from the rocks and transport them to other locations. This process could have led to the formation of mineral deposits that are valuable for use in batteries.
The study has important implications for understanding the formation of mineral deposits. It could also lead to new ways of extracting minerals from rocks, which could help to make batteries more affordable and environmentally friendly.
X-rays reveal hidden mineral wealth in rocks
X-ray imaging has revealed previously unknown mineral wealth in rocks near the Earth's surface. The discovery, made by researchers at the University of Sydney, could lead to new mining opportunities and help to secure the supply of critical materials for batteries and other technologies.
The X-ray imaging technique, called X-ray fluorescence (XRF), is able to detect the presence of specific elements in rocks. The researchers used XRF to scan rocks from a region of Western Australia known as the Yilgarn Craton. They found that the rocks contained high concentrations of lithium, cobalt, and nickel – three elements that are essential for the production of batteries.
The discovery of these mineral deposits is significant because it could help to secure the supply of these critical materials for batteries. Batteries are used in a wide range of applications, including electric vehicles, laptops, and smartphones. The demand for batteries is growing rapidly, and this is putting a strain on the supply of critical materials.
The discovery of these new mineral deposits could help to alleviate this strain and ensure that there is enough supply of critical materials to meet the growing demand for batteries. This could have a major impact on the development of electric vehicles and other clean energy technologies.
The researchers say that the XRF imaging technique could be used to explore for mineral deposits in other regions of the world. This could lead to the discovery of new sources of critical materials and help to secure the supply of these materials for future generations.
