"Swiss Breakthrough Aids Diamond Hunters"

Swiss geologists from ETH Zurich and the University of Melbourne have discovered that the composition of the mineral olivine in rocks can indicate the presence of diamonds, with higher magnesium content indicating a higher likelihood of diamonds. This breakthrough could significantly simplify the search for diamonds, which traditionally involves identifying the rare kimberlite rock before beginning the complex process of diamond detection. The new method is faster and has already been adopted by some companies.

"Lost Meteor Impact Creates Mysterious Yellow Glass in Libyan Desert"

Libyan desert glass, a mysterious yellow glass found in the Libyan desert, has long puzzled scientists about its origin. A recent study using advanced microscopy techniques has identified the glass as originating from a meteorite impact on Earth's surface. The study found minerals in the glass that can only form under high temperature and pressure conditions, providing evidence for the meteorite impact theory. However, the exact location and size of the parental crater remain unknown, leaving more mysteries to be solved.

"Lost Meteor Impact Creates Mysterious Yellow Glass in Libyan Desert"

Libyan desert glass, a mysterious yellow glass found in the Libyan desert, has been identified as originating from the impact of a meteorite on Earth's surface. Advanced microscopy techniques revealed the presence of zirconium oxide minerals, including cubic zirconia and a rare polymorph called ortho-II, indicating high temperatures and pressures consistent with a meteorite impact. However, the location of the parental crater remains unknown, raising further questions for future investigations.

"Lost Meteor Impact Creates Mysterious Yellow Glass in Libyan Desert"

Libyan desert glass, a mysterious yellow glass found in the Libyan desert, has been the subject of debate among scientists for almost a century. Advanced microscopy technology has now revealed that the glass originated from a meteorite impact on Earth's surface. The study identified different types of zirconium oxide minerals in the glass, indicating high temperatures and pressures that can only be achieved through a meteorite impact or atomic bomb explosion. However, the location of the parental crater, where the meteorite hit, remains unknown, posing more mysteries to be solved.

The Secret Behind the Radiant Glow of "Golden" Fossils Revealed

Scientists from The University of Texas at Austin have discovered that the golden shimmer of fossils from Germany's Posidonia shale is not due to pyrite (fool's gold) as previously believed, but rather a blend of minerals. The fossils, which are among the world's best-preserved specimens of sea life from the Early Jurassic, primarily consist of phosphate minerals. This finding provides insights into the fossilization process and the role of oxygen in their formation. The research challenges long-standing theories about exceptional fossil preservation and highlights the importance of oxygenation in enhancing preservation.

NASA's Curiosity Rover Discovers Dragon-Like Skeleton on Mars

NASA's Mars Curiosity rover captured an image that left some people seeing a fossilized Martian dragon, but NASA explains that the odd-shaped rocks on Mars have their origin in the ancient past when liquid water seeped through the cracks in the rock, bringing minerals along with them. The image was captured utilizing the rover's Chemistry and Camera (ChemCam) instrument, which identifies the chemical and mineral compositions of rocks and soils. Curiosity has taken over one million images since landing on the Red Planet in August of 2012.
