Crystal Quartz Could Reveal The Reason Why Our Magnetic Field Is So Old collective-evolution
Charged particles moving with the flow of molten rock rising away from a heated core created what we now refer to as Earth’s geomagnetic field. The core is thought to be about a billion or so years old , though some studies have found that the resulting magnetic field dates back as far as 4 billion years ago . Such opposing figures have only added to the mystery of the magnetic field’s actual age. But new evidence could finally provide the breakthrough needed to give us some answers. Research by Kei Hirose from the Tokyo Institute of Technology in Japan suggests that the formation of tiny crystals of quartz far beneath our feet may be the answer to accurately modelling the buoyancy of our planet’s deep molten rock. The New Core Paradox , or the mismatch between the age we think our planet’s core is, and the age of its magnetic field, occurs in part because of how heat from the inner core forces currents of gooey rock up toward the crust from the ...
