The Australian Earth Sciences community is proud to host the 10th triennial scientific meeting of The International Association of Geoanalysts. Geoanalysis meetings are the main forum to meet with colleagues and discuss the latest developments and future needs in the field of measurements applied to geological and environmental materials. Geoanalysis 2018 will be held from 8th to 13th of July in Sydney, Australia. Scientific sessions will take place in excellent conference facilities situated on the park-like campus of Macquarie University. The conference will be rounded off with topical short courses given by experts in the field and a field trip along the beautiful New South Wales coast. We look forward to welcoming you to Sydney in July 2018.
