Field Days in Devon
IGI regularly take groups to geological localities in Devon (and north Somerset), typically as part of geochemical training courses for oil companies or as guides for A-

During the journey to Mid Devon, the roof of the 'Cornubian granite' massif is exposed on Dartmoor. Though primarily feldspar, quartz and micas, a variety of granite types are recognised, with varying ?flow textures and mineralogy. Sedimentary xenoliths are seen within the granite mass and the contact zone and metamorphic aureole is also well exposed. Evidence for the migration and expelling of exotic mineralising fluids is preserved, with old mine dumps offering opportunities to collect associated mineral samples.
