Polar volcanic rock search – equilibrium conditions Gravitational force F g = ma in equilibrium with magnetic force F m = gecB • Dirac charge (g = 68.5) → equilibrium above the coremantle boundary (B) for: m < 4·10 14 GeV • (solid) mantle convection brings up monopoles to the surface Over geologic time, accumulation in the mantle beneath the geomagnetic poles for a wide range of masses and charges 14
Polar volcanic rock search – samples High latitude (>63 o ), mantle derived • Hotspot (Iceland, Jan Mayen, Ross Island) • Mid-ocean ridge (Iceland, Gakkel Ridge) • Large igneous province (North Greenland, East Greenland) • Isotopic content indicating deep origins (Coleman Nunatak) Crushed to reduce magnetisation for precise magnetometer measurement 15
