Gold from ice?
Chris Clark is just returned from Ireland having presented a keynote talk to the annual conference of the Irish Association for Economic Geology.
The conference mostly comprised geologists and geophysicists from companies and consultancies engaged in mineral exploration (looking for zinc, gold, platinum, etc). Geochemical traces of valued minerals have been smeared across the landscape by the action of ice flow during the last glaciation, and Chris argued that improved understanding of such flow directions and the processes of sediment transport (including drumlinisation) should assist in finding resources.
Following a number of requests from companies, Chris is now helping to further develop these ideas.
