Fine-grained, pristine ash required
Dear All,
We are conducting a project which assesses the interaction of volcanic ash and anthropogenic pollutants. We are in need of a very fine-grained basaltic-basaltic andesite ash sample, collected prior to rainfall, and in a non-polluted atmosphere (i.e. not near or over a big city/industrial area). We require at least 150g of ash. Basaltic ash is usually fairly coarse so we require ash from a fairly unusual, explosive eruption (phreatomagmatic interaction is fine).
If you are able to help, I would be very grateful if you could contact me as soon as possible: Claire.horwell@xxxxxxxxxxxx
Best wishes,
Claire Horwell
