    on May 4, 2017 at 1:35 am

    One of the last dinosaurs living in Africa before their extinction 66 million years ago has been discovered in a phosphate mine in northern Morocco. A study of the fossil suggests that following the breakup of the supercontinent Gondwana in the middle of the Cretaceous period, a distinct dinosaur fauna evolved in Africa. […]

  • Geologists use radioactive clock to document longest earthquake record
    on May 2, 2017 at 4:12 pm

    Using radioactive elements trapped in crystallized, cream-colored 'veins' in New Mexican rock, geologists have peered back in time more than 400,000 years to illuminate a record of earthquakes along the Loma Blanca fault in the Rio Grande rift. It is the longest record of earthquakes ever documented on a fault. […]

  • 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. […]

  • Mining: Bacteria with Midas touch for efficient gold processing

  • Copper-bottomed deposits
    on March 15, 2017 at 1:45 pm

    Researchers have studied over 100,000 combinations to establish the depth and number of years required for magma to produce a given amount of copper. The same scientists have also devised a model that can detect the quantity of copper held in a deposit by means of a simple factor analysis. The research will make it possible to estimate the potential for mining the metal before beginning any drilling. […]

  • 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. […]

  • Svalbard's electric power could come from hydrogen
    on February 7, 2017 at 3:43 pm

    The energy supply to Longyearbyen, midway between continental Norway and the North Pole, is a hot topic in the climate debate. Longyearbyen is the largest settlement and the administrative centre of Svalbard, a Norwegian archipelago in the Arctic Ocean. Today, Longyearbyen obtains its electric power and district heating from its coal power plant, the only one in Norway. […]

  • Scientist studies whether solar storms cause animal beachings
    on February 6, 2017 at 1:38 pm

    A long-standing mystery among marine biologists is why otherwise healthy whales, dolphins, and porpoises -- collectively known as cetaceans -- end up getting stranded along coastal areas worldwide. Could severe solar storms, which affect Earth's magnetic fields, be confusing their internal compasses and causing them to lose their way? […]

  • Study helps explain why uranium persists in groundwater at former mining sites

  • Modeling magma to find copper
    on January 12, 2017 at 1:37 pm

    Copper is an essential element of our society with main uses in the field of electricity and electronics. About 70% of the copper comes from deposits formed several million years ago during events of magma degassing within Earth's crust just above subduction zones. Despite similar ore forming processes, the size of these deposits can vary orders of magnitude from one place to another, the main reason of which has remained unclear. A new study suggests that the answer may come from the volume of magma emplaced in the crust and proposes an innovative method to better explore these deposits. […]

  • New method to remove nickel from contaminated seawater
    on January 11, 2017 at 3:29 pm

    The same deposit that builds up in many tea kettles or water pipes in areas where calcium-rich water is the norm might be just the (cheap) ticket to rid contaminated seawater of toxic metals. […]

  • Newly discovered 'Casper' octopod at risk from deep-sea mining
    on December 19, 2016 at 6:45 pm

    Last spring, researchers made headlines with the discovery of what was surely a new species of octopod, crawling along the seafloor at a record-breaking ocean depth of more than 4,000 meters off of Hawaii. Now, a report reveals that these ghost-like, deep-sea octopods lay their eggs on the dead stalks of sponges attached to seafloor nodules rich in the increasingly valuable metals used in cell phones and computers.
