SPP 2017:  Mountain Building Process in Four Dimensions (4D-MB)

• Subject Area: Geosciences
• Term: since 2017
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 313806092

The goal of this proposal is to foster interdisciplinary solid-earth research during the second three-year phase of 4D-MB. Special focus is on controversies that have arisen as the international AlpArray seismic experiment draws to a close and processed data are becoming available for interpretation.The proposal entails two components: (1) An administrative arm that will facilitate bringing together scientists in collaborative groups that address their research interests and the main themes of 4D-MB; (2) a research arm that delves into processes underlying the so-called Neogene Orogenic Revolution, the explosive expansion and indentation of the Alpine mountain belts that began in late Paleogene and Neogene time. Keeping these two components together will require hiring a highly qualified early career scientist (postdoc) for the duration of the second phase of the priority programme.The research arm above is but one of three interdisciplinary working groups (WGs) that replace the four activity fields of the first phase in order to integrate the broad spectrum of geosciences in 4D-MB (see descriptions submitted separately):WG A: Neogene Orogenic (R)evolution – from bottom to top & back in timeWG B: Bridging models of Alpine Deformation and Sedimentary SystemsWG C: Active Tectonics at the Alps-Dinarides TransitionMeasures proposed to network projects in 4D-MB include (1) annual November meetings of all PIs and early career scientists (70 people), and including invited guest speakers; (2) small, freely schedules workshops (10-20 people) for working groups; (3) annual three-day short courses on specialized topic or themes aimed at early career scientists; (4) 5-7 day field trips across the Alpine orogen that highlight relationships between deep-seated and surface processes.All of these measures are continuations of successful initiatives in the first phase of 4D-MB. Further to this, members of 4D-MB will step up their already notable efforts to collaborate with AlpArray members across Europe and beyond. Several initiatives have been proposed for Collaborative Research Groups within AlpArray, adding to the impressive number already founded and/or co-founded by members of 4D-MB.As 4D-MB enters its second phase, we are looking ahead to establish a sustainable culture of collaboration between specialized branches of the geosciences. At this writing, efforts are underway to initiate new European projects in other tectonically active regions of the world.
