  • Diamonds show Earth still capable of ‘superhot’ surprises
    on September 21, 2017 at 1:55 pm

    Diamonds may be ‘forever’ but some may have formed more recently than geologists thought. A study of 26 diamonds, formed under extreme melting conditions in the Earth’s mantle, found two populations, one of which has geologically ‘young’ ages. The results show that certain volcanic events on Earth may still be able to create super-heated conditions previously thought to have only existed early in the planet’s history before it cooled. The findings may have implications for diamond prospecting. […]

  • Mineral resources: Exhaustion is just a myth, say scientists
    on May 2, 2017 at 3:40 pm

    Recent articles have declared that deposits of mineral raw materials (copper, zinc, etc.) will be exhausted within a few decades. An international team of scientists, however, has shown that this is incorrect and that the resources of most mineral commodities are sufficient to meet the growing demand from industrialization and future demographic changes. Future shortages will arise not from physical exhaustion of different metals but from causes related to industrial exploitation, the economy, and environmental or societal pressures on the use of mineral resources. […]

  • Diamond’s 2-billion-year growth charts tectonic shift in early Earth’s carbon cycle
    on February 23, 2017 at 3:21 pm

    A study of tiny mineral 'inclusions' within diamonds from Botswana has shown that diamond crystals can take billions of years to grow. One diamond was found to contain silicate material that formed 2.3 billion years ago in its interior and a 250 million-year-old garnet crystal towards its outer rim, the largest age range ever detected in a single specimen. Analysis of the inclusions also suggests that the way that carbon is exchanged and deposited between the atmosphere, biosphere, oceans and geosphere may have changed significantly over the past 2.5 billion years.
