I am a regional geologist, working on large-scale regions in complex tectonic/geodynamic settings such as the Alpine-Mediterranean area (current projects) where surface, crustal and mantle processes interact. My research focuses on the formation and structural evolution of sedimentary basins, oceans and mountain chains, to better understand the processes that link the motions/deformations of the Earth’s mantle and crust. This involves working on different temporal (Ma – 100s Ma) and spatial (outcrop to plate tectonics) scales and integrating various disciplines of the Earth Sciences, especially field geology, geodesy and geophysics (seismic data).

CURRENT PROJECTS

  • New kinematic reconstructions of the Adriatic Plate as a key to understanding subduction processes in the Western Mediterranean (KAPMED)

Project in collaboration with Prof. Dr. Mark Handy (FU Berlin) and Prof. Kamil Ustaszewski (Jena University), funded by the DFG (first PI)

This project aims to generate new kinematic reconstructions of the Western Mediterranean region, focusing on the motion of the Adriatic microplate (Adria). Adria is entirely surrounded by deformed margins comprising the Alps, Dinarides, Apennines and the Calabrian Arc that form during the Eurasia-Africa convergence. Adria is the indenting upper plate in the Alps, but the lower plate of the Dinarides and Apennines. Moreover, the Apennines have been the site of Oligo-Miocene rollback subduction and pronounced upper-plate extension (Liguro-Provençal and Tyrrhenian basins). Reconstructing the past motion of Adria is therefore key to understand how contrasting orogenic styles develop within the same overall convergent tectonic regime.

Figure 1: Tectonic map of western Mediterranean with main Cenozoic structures and geological-geophysical transects used to reconstruct the post-20 Ma motion path of the Adriatic plate (see Le Breton et al., 2017).

Figure 2: Map-view reconstruction of the motion of tectonic plates and frontal thrusts in the Western Mediterranean since 20 Ma (see Le Breton et al. 2017 and supplementary information for further explanations).

 

Our Neogene kinematic reconstructions of Adria (Le Breton et al. 2017) incorporates estimates of post-20 Ma shortening and extension in the Apennines, Alps, Dinarides and Sicily Channel Rift Zone and reveals that Adria rotated counterclockwise of c. 5º relative to Europe and translated c. 110 km to the NW as it subducted beneath the European Plate to the west and to the east, while indenting the Alps to the north. Plate convergence exceeds crustal shortening in all orogens surrounding Adria; we attribute this difference to tectonic erosion and crust-mantle decoupling of the Adriatic lithosphere, expressed differently in the three orogens: (1) delamination during rollback in the Apennines, (2) northward motion of the Dacia Unit between the Dinarides and Europe (Moesia), and (3) eastward lateral extrusion of the Tauern window in the Eastern Alps during northward indentation of Adria into Europe.

I have now reconstructed the motion of Adria and the Western-Central Mediterranean/Alpine area back to Triassic time and incorporated my regional model into the latest global plate models of the EarthByte Group, Sydney (Müller et al. 2019). The new version of GPlates (2.1) allows quantitative analyses of continental deformation during rifting and orogenesis (e.g. evolution of crustal thickness through time, stretching/shortening factor, strain rate). In this paper, I have made a deforming mesh that models the Alpine contractional deformation as well as the upper plate extension in the Pannonian Basin and Aegean. I am now working on refining the deforming mesh at more regional scales.

  • Linking surface kinematics to deep structure of the Adriatic indenter near a potential subduction-polarity switch – the Giudicarie Belt, southern Alps

PhDs: Vincent Verwarter (FU Berlin) and Azam Jozi Najafabadi (GFZ Potsdam)

Project in collaboration with Prof. Dr. Mark Handy (FU Berlin) and Dr. Christian Haberland (GFZ Potsdam), funded by the DFG (SPP - Mountain building processes in 4D)

This is a seismotectonic study of the Giudicarie Belt (GB), a transverse zone that subdivides the Alps into an eastern part marked by orogen-parallel extrusion of orogenic crust and a western part with well-developed pro- and retro-wedges. Our project tests the idea that Miocene kinematics at the leading edge of the Adriatic indenter is related to a proposed switch in subduction polarity along the Alpine chain as imaged in body-wave tomography, from a SE-dipping slab anomaly in the west to a subvertical to north-dipping anomaly in the east.

  • Extension and reactivation of continental margin during convergence

Both following projects focuses on better understanding the processes generating extensional faulting in compressional regime, more particularly in the foreland area of mountain belts using seismic-reflection data. The first case study is the Upper Austrian Molasse Basin, foreland of the Alps, and the second is the Sicily Channel Rift Zone (extensional rift system between Sicily and Tunisia) and Gela Basin (south of Sicily), southernmost foredeep of the Apennines.

PAST PROJECTS

  • NW Colombia – Formation and evolution of the San Jacinto fold belt and Lower Magdalena Valley basin

PhD of Alejandro Mora (Hocol S.A. Bogotá and GFZ Potsdam)

This project studies the link between forearc basin formation and evolution (detailed tectonostratigraphic analyses of the San Jacinto fold belt and Lower Magdalena Valley Basin in NW Colombia) and specific subduction/collision stages between the Caribbean and South American plates.

Figure 8: Paleotectonic reconstructions at 75, 55, 45, and 35 Ma, illustrating the displacement of the Caribbean Plate relative to fixed South America and the major change in convergence obliquity, which occurred between 55 and 45 Ma (see Mora et al. 2017).


  • Differential spreading along the NE Atlantic Ocean and post-breakup deformation of the NW European Margin

During my PhD, I investigated how compressional deformation of the NW European Margin may have resulted from variations in the direction and rate of sea-floor spreading along the various ridges of the NE Atlantic. It involved a new kinematic reconstruction of the complex spreading history of the NE Atlantic and structural analyses along the NW European Margin (Le Breton et al., 2012) and along the Great Glen Fault in Scotland (Le Breton et al., 2013). I discussed in the PhD thesis the effect of mantle plumes (Tristan da Cunha and Iceland) on rifting and spreading processes in the South and NE Atlantic, respectively (see Le Breton 2012).

Figure 9: Map-view reconstruction of the opening of the NE Atlantic, formation of the Jan Mayen Microcontinent (JMMC) and post-breakup deformation along the NW European Continental (in red), red circle represents location of Iceland Mantle Plume head (see Le Breton et al. 2012).

 

  • Post-glacial rebound of Iceland during Holocene time

During my MSc, I studied the combined effects of a ridge and a hotspot on surface deformation processes in Iceland. I mapped paleo-shorelines all around Iceland using digital elevations models, field data and a review of previous studies in order to quantify Holocene vertical displacements of the whole island, with a focus on the post-glacial rebound following the Weichselian glaciation and I discussed its spatial variations in terms of ice unloading and rheology (Le Breton et al., 2010).
