"Uncovering the Hidden Value of Fool's Gold: The Lithium Treasure Within"

Scientists in West Virginia have discovered significant amounts of lithium within pyrite, or fool's gold, found in mine tailings, offering a potential sustainable source of the rare earth element for renewable energy technologies. This discovery could provide a steady supply of lithium without the need for environmentally harmful mining, as demand for the element skyrockets due to the transition to greener energy sources. The study suggests that certain shales containing pyrite could serve as a lithium source, potentially revolutionizing the way lithium is obtained for use in batteries and other applications.

Uncovering the Truth Behind the 'Golden' Fossils from the Jurassic

Scientists have discovered that phosphate minerals with yellow calcite, not pyrite, are responsible for the golden glow of fossils embedded in Germany's Posidonia Shale. The fossils, which include ammonites, bivalves, and crustaceans, were analyzed using a high-powered scanning electron microscope, revealing that the surrounding shale contained microscopic clusters of pyrite crystals, but the fossils themselves were phosphatized or yellow calcite. The research sheds light on the fossilization environment and the chemical reactions necessary for fossilization to occur.

Uncovering the Truth Behind the 'Golden' Fossils from the Jurassic

Scientists have discovered that the golden hue of fossils embedded in Germany's Posidonia Shale is not due to pyrite, as previously thought, but rather phosphate minerals with yellow calcite. The fossils, which include ammonites, bivalves, and crustaceans, were found to be phosphatized or yellow calcite, with only a few framboids of pyrite present. The research revealed that while an anoxic seafloor set the stage for fossilization, it took a burst of oxygen to cause the chemical reactions necessary for fossilization to occur.

Uncovering the Origins of Exceptional Fossil Preservation.

Scientists at The University of Texas at Austin and collaborators found that the golden hue of fossils from Germany's Posidonia shale is not from pyrite, but from a mix of minerals that hints at the conditions in which the fossils formed. The fossils, which are among the world's best-preserved specimens of sea life from the Early Jurassic, are primarily made up of phosphate minerals, revealing key details about the fossilization environment. The research suggests that although an anoxic seafloor sets the stage for fossilization, it took a pulse of oxygen to drive the chemical reactions needed for fossilization.
