The 20th INQUA World Congress - "Life on the Edge" - to be held in the Convention Centre Dublin, aims to bring together all stakeholders, to promote improved communication and international collaboration in experimental and applied aspects of Quaternary research. Quaternary research also provides a direct understanding of geological change including sedimentation and deposition of rock layers and natural energy resources. Applied Quaternary Geology is therefore very relevant for the Mining and Energy sectors, Geotechnology, Water and Hydrogeology, land surveys and planning, and large-scale engineering projects.
