Potential temperature and margin width control melt volume at rifted margins Gang Lu and Ritske S. Huismans Passive continental margins may have a wide variety of structural and magmatim styles, but the controlling factors of magmatism remain controversial. Common explanations …
Raiders of the Lost Arc by Eirik Wiese, Felix Halpaap, Ronny Tømmerbakke, Sebastian Wolf Abstract: In this more or less scientific geolunch, we present geological and some sociocultural revelations from our field trip to the Brasilia belt in southern Minas Gerais …

Post-Caledonian fault activity in W-Norway: onshore and offshore don’t match – or do they? by Ksienzyk, A.K., Wemmer, K., Rotevatn, A., Fazlikhani, H., Jacobs, J., Fossen, H. K-Ar or Ar-Ar analyses of fault gouge fine fractions are becoming well-established methods …
Silica diagenesis and physical properties of Cenozoic rocks in the North Viking Graben, northern North Sea by Thilo Wrona, Christopher A-L. Jackson, Mads Huuse and Kevin G. Taylor As an introduction, I thought it would be nice to present some …
Long-term coupling and feedbacks between surface processes and tectonics during rifting Whereas significant efforts have been made to understand the feedback between mountain building and surfaces processes, limited research has been done on the relationship between surface processes and extensional tectonics. …
Inverse modeling of Eocene to mid-Pliocene landscape evolution in Scandinavia using offshore sediment volumes The origin of high topography in Scandinavia is highly debated, both in terms of its age and the underlying mechanism for its formation. Traditionally, the current …

Water migration in the subduction mantle wedge: a two-phase flow approach Hongliang Wang, Ritske S. Huismans, and Stéphane Rondenay Subduction zones are the main entry points of water into earth’s mantle and play an important role in the global …
Modeling potential paleoearthquakes based on results from subaquatic mass movements in Western Norway During my PhD as a Quaternary geologist, I did quite some work on turbidite paleoseimology in west- and mid-Norway, with some very interesting outcomings. I was further …
Three-dimensional thermo-mechanical modelling unravels the complex deformation history of oblique rifts, transtensional margins, and gneiss domes Throughout the Wilson cycle the obliquity between lithospheric plate motion direction and nascent or existing plate boundaries prompts the development of intricate three-dimensional (3-D) …
