Article
Full-text available
The sinking remnant of a surface plate crosses and interacts with multiple boundaries in Earth's interior. Here, we specifically investigate the prominent dynamic interaction of the sinking plate portion with the upper-mantle transition zone and its corresponding surface elevation signal. We unravel, for the first time, that the collision of the si...

Full-text available
As the Earth's primary mode of planetary cooling, the oceanic plate is created at mid-ocean ridges, transported across the planet's surface, and destroyed at subduction zones. The evolution of its buoyancy and rheology during its lifespan maintains the coherence of the plate as a distinct geological entity and controls the localised deformation and...

A standard internet image search on a scientific topic is common practice, and offers a plethora of images. However, the suggested images provide neither a guarantee in the accuracy of the science content being portrayed, nor in their clarity or artistic elegance. Being curated by both scientists and artists, the online s-Ink collection (https://s-...
Article
Full-text available
Subduction zones are pivotal for the recycling of Earth’s outer layer into its interior. However, the conditions under which new subduction zones initiate are enigmatic. Here, we constructed a transdisciplinary database featuring detailed analysis of more than a dozen documented subduction zone initiation events from the last hundred million years....

Geodynamic modelling provides a powerful tool to investigate processes in the Earth's crust, mantle, and core that are not directly observable. However, numerical models are inherently subject to the assumptions and simplifications on which they are based. In order to use and review numerical modelling studies appropriately, one needs to be aware o...

Full-text available
Subduction zone formation may be both horizontally and then vertically driven, according to a 4D evolution model of the Puysegur margin, New Zealand. This suggests that the current endmember classification of subduction initiation must be expanded.
Research Proposal
Full-text available
Academia currently ranks academics and the ranking is mainly based on one single, flawed number, the h-index. In contrast, ProAc is a data-based, visual toolbox that allows to profile, and not rank, academics based on not just one, but a selection of elaborate indices. Crucially, this will reduce unnecessary competition between academics and curren...

Full-text available
Venus is currently characterized by stagnant-lid mantle convection, but could have previously experienced episodes of global resurfacing due to lithospheric overturn. Using numerical models of Venus’s interior, we attempt to explain Venus’s surface characteristics in the context of interior evolution and to understand how Venus’s tectonic history h...

The accurate representation of data is essential in science communication. However, colour maps that visually distort data through uneven colour gradients or are unreadable to those with colour-vision deficiency remain prevalent in science. These include, but are not limited to, rainbow-like and red–green colour maps. Here, we present a simple guid...
Article
Full-text available
Current Venus tectonics suggests a stagnant lid mode of mantle convection. However, the planet is debated to enter an episodic regime after long quiescent periods, driven by resurfacing due to rapid subduction and global crustal recycling. Tessera regions that cover approximately 10% of Venus’ surface appear to be strongly deformed, which suggests...
Article
Full-text available
Slab orphaning is a newly discovered phenomenological behavior, where the slab tip breaks off at the top of the lower mantle (~660 km depth) and is abandoned by its parent slab. Upon orphaning, subduction continues uninterrupted through the lateral motion of the parent slab above 660 km depth. In this work, we present a regime diagram for the range...

Today's geodynamic models can, often do and sometimes have to become very complex. Their underlying, increasingly elaborate numerical codes produce a growing amount of raw data. Post-processing such data is therefore becoming more and more important, but also more challenging and time-consuming. In addition, visualising processed data and results h...

Unlike Earth, Venus lacks discrete, moving plates. Analogue model experiments suggest that observed hints at plate recycling do indeed indicate current, localized destruction of the Venusian surface.
Article
Full-text available
The long-wavelength surface deflection of Earth's outermost rocky shell is mainly controlled by large-scale dynamic processes like isostasy or mantle flow. The largest topographic amplitudes are therefore observed at plate boundaries due to the presence of large thermal heterogeneities and strong tectonic forces. Distinct vertical surface deflectio...
Article
Full-text available
Subduction initiation is a key in understanding the dynamic evolution of the Earth and its fundamental difference to all other rocky planetary bodies in our solar system. Despite recent progress, the question about how a stiff, mostly stagnant planetary lid can break and become part in the global overturn of the mantle is still unresolved. Many mec...
Article
In order to link the geochemical signature of hot spot basalts to Earth's deep interior, it is first necessary to understand how plumes sample different regions of the mantle. Here, we investigate the relative amounts of deep and shallow mantle material that are entrained by an ascending plume and constrain its source region. The plumes are generat...

Article
Full-text available
Recent advances in numerical modelling allow global models of mantle convection to more realistically reproduce the behaviour at convergent plate boundaries; in particular, the inclusion of a free surface at the outer boundary has been shown to facilitate self-consistent development of single-sided subduction. This allows for a more extensive study...
Article
Full-text available
We present temporally evolving 3-D global mantle convection models with single-sided subduction and a free surface in both 3-D Cartesian and fully spherical geometry. Special focus is given to the spontaneous development of three-dimensional structures atthe surface and in the upper mantle. We find that an arcuate shape is the natural form for tren...
Thesis
Full-text available
The present-day structure of Earth’s interior is fairly well known thanks to observations. The dynamic processes involved in forming such a rocky planet like Earth are, however, still not fully understood. This thesis therefore aims at a better understanding of plate tectonics, a crucial dynamical feature within the global framework of mantle conve...
Article
Full-text available
Calculating surface topography in geodynamic models is a common numerical problem. Besides other approaches, the so-called sticky air approach has gained interest as a free-surface proxy at the top boundary. The often used free slip condition is thereby vertically extended by introducing a low density, low viscosity fluid layer. This allows the air...
Article
The dynamics of the Earth's lithosphere and mantle are strongly influenced by its upper mechanical boundary condition. For instance, our previous work has shown that a necessity for the evolution of Earth-like, single-sided subduction is a free surface, which allows for vertical movement of the two converging plates, i.e. the development of surface...
Article
Subduction zones on present-day Earth are strongly asymmetric features (Zhao 2004) composed of an overriding plate above a subducting plate that sinks into the mantle. Our recent advances in numerical modelling allow global mantle convection models to produce single-sided subduction self-consistently by allowing for free surface topography on and l...

Full-text available
Subduction zones on present-day Earth are strongly asymmetric features (Zhao 2004) composed of an overriding plate above a subducting plate that sinks into the mantle. While global self-consistent numerical models of mantle convection have reproduced some aspects of plate tectonics (e.g. Tackley 2000, van Heck & Tackley 2008), the assumptions behin...
Conference Paper
Full-text available
3D geodynamic modelling of lithospheric-scale deformation remains a challenge as it requires scal-able multigrid algorithms that perform well in the presence of large and abrupt jumps in viscosity. In recent years, we have developed LaMEM (Lithosphere and Mantle Evolution Model), which was originally a finite element code, that can be combined with...
Article
Full-text available
Shear-heating induced localization has been suggested as a potentially important mechanism for breaking the litho-sphere. Yet, the physical parameters that control the on-set of this instability remain unclear. We therefore per-formed systematic 2-D simulations of visco-elasto-plastic lithospheric deformation in which we addressed the effects of va...
Article
Full-text available
Previous dynamical models of global mantle convection indicated that a visco-plastic rheology is successful in generating plate tectonics-like behaviour self-consistently (Moresi et al., 1998; van Heck and Tackley, 2008). Yet, these models fail to create Earth-like plate tectonics: so far in all published models subduction is two-sided and more or...
Article
Here, our recent progress in understanding the large-scale dynamics of the mantle convection - plate tectonics system is summarised, with particular focus on the influence of realistic mineral physics and a free surface. High pressure and temperature experiments and calculations of the properties of mantle minerals show that many different mineral...
Article
The understanding of thermo-mechanical processes forming mountain ranges and plateaus, such as the Tibetan Plateau, is still incomplete. Therefore, interpretations of the same geophysical observations with respect to lithospheric processes in general and lithospheric rheology in particular vary significantly. This is, for example, the case for inte...
Article
Full-text available
Topography is a direct observable of the interaction between the Earth's internal and external dynamics. Therefore, it is important for numerical models of lithospheric deformation to compute topography accurately. Earth's surface is a so-called free surface, which means that both normal and shear stress should vanish at this interface. It has been...

Visualisation is one of the three main pillars of science. Without visualisation, research is useless. With unscientific visualisation, research is not only useless, but can actually become a problem: Unscientific visualisation can distort the data significantly and hence confuse or even mislead scientists. This project raises awareness of unscientific visualisation; provides guidelines towards scientific visualisation; facilitates scientific visualisation; aims for a better science.

When and how ocean-plate tectonics starts on rocky planets like the Earth is - still - one of the key open questions of Earth Sciences. When and how new subduction zones initiate on a rocky planet with ongoing ocean-plate tectonics is yet another key open question of the Earth Sciences. Answering these two - different - questions demands a collaborative and interdisciplinary effort, fundamentally new approaches, state-of-the-art modelling and additional observations on Earth and other planets like Venus.

The fascinating, dynamic subduction zones are pivotal for a planet's evolution. Their buoyancy, rheology, and geometry are, unfortunately, well hidden from direct observations by human beings. The surface topography arising on top of subduction zones is, however, strongly linked to subduction dynamics, while also directly accessible for observations. Surface topography thus provides a unique opportunity to constrain the dynamics and structure of a subduction zone; and numerical models are the perfect tool to do so.
