Hi, I'm Lei, a postdoc at OMG, CAS. I use numerical modelling methods to gain understanding of plate weakening processes, e.g., subduction zones, continental breakup, continental marginal magmatism etc. I am enthusiastic in investigating the interaction between lithosphere and mantle flow underneath. Geoscience nourishes my global view, which drives me with a strong curiosity to explore and understand the different cultures, histories and especially the food!! You can find more about me at https://zhibinlei.github.io/, Twitter @Lei_geodynamics and reach me via email (leiz2@cardiff.ac.uk).

Dual inward dipping subduction: A Christmas Cracker Model

Dual inward dipping subduction: A Christmas Cracker Model

A recent research finds that dual inward dipping subduction framework, after considering thermal dependent deformation mechanisms, can pull apart the middle overriding plate (Lei and Davies, 2023), just like pulling Christmas crackers from both ends! Dual inward dipping subduction (DIDS) occurs when the overriding plate is decoupled with two subducting slabs dipping towards each other. DIDS is fou ...[Read More]

How has the Gibraltar slab influenced the Alboran domain deformation?

How has the Gibraltar slab influenced the Alboran domain deformation?

Figure 1. Topography of the Gibraltar Arc region. The shaded area indicates the position of positive seismic velocity anomaly supposedly representing the position of the slab at 270 km depth from seismic tomography (Amaru, 2007). The purple line shows the position of the modelled cross-section for the model shown in this blog. Blue dots indicate the regional intermediate seismicity (between 40 km ...[Read More]

Meet the blog illustrators: Vojta Hýbl

Vojta Hýbl from the blog illustration team (photo taken by India Hunkin). Spreading research news to a broad audience is important but difficult work for scientists. Luckily, we have an amazing illustration team who are happy to share their artistic creation. Their artwork has helped us expand the readership and made our blogs increasingly popular. This week, I am excited to introduce Vojta Hýbl f ...[Read More]

G-ADOPT: a next generation computational modelling framework for geodynamics

Schematic illustrating core components of G-ADOPT, an Australian based cross-NCRIS project, principally developed at the Australian National University (ANU), with partners at the University of Sydney and Imperial College London. G-ADOPT is supported by the Australian Research Data Commons (ARDC), with co-investment from AuScope, the National Computational Infrastructure (NCI) and Geosciences Aust ...[Read More]
