• Geochemists measure new composition of Earth’s mantle
  

  What is the chemical composition of the Earth’s interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth’s deep interior often provide such information. Geochemists at the Universities of Münster (Germany) and Amsterdam (N more

• New Measurement Device: Carbon Dioxide As Geothermometer
  

  For the first time it is possible to measure, simultaneously and with extreme precision, four rare molecular variants of carbon dioxide (CO2) using a novel laser instrument. It is thus able to measure the temperature during the formation of CO2-binding carbonates and carbonaceous fossils completely more

• Rust never sleeps
  

  Like iron flowing through the blood stream, iron minerals course through the ground. These minerals are used to make steel and other metal alloys used in everything from cell phone components and cars to buildings, industrial equipment and infrastructure. Unfortunately, when exposed to oxygen and mo more
