The Deformation Mechanisms, Rheology and Tectonics (DRT) conference is a biennial international meeting that has been running for 40 years, organised and hosted by academic staff from different European universities. DRT is one of the main world forums for presenting and discussing research in the fields of rock deformation, structural geology, rheology, tectonics, microstructures, rock physics and interactions between deformation and metamorphic/diagenetic reactions.
