DOI http://dx.doi.org/10.1016/j.tecto.2006.09.017 Abstract We present a new model for the lithospheric structure of the transitions between Laurentia, Avalonia and Baltica in the North Sea, northwestern Europe based on 2¾D potential field modelling of MONA LISA profile 3 across the Central Graben, with constraints from seismic P-wave velocity models and the crustal normal incidence reflection section along the profile. The model shows evidence for the presence of upper-and lower Palaeozoic sedimentary rocks as well as differences in crustal structure between the palaeo-continents Laurentia, Avalonia and Baltica. Our new model, together with previous results from transformations of the gravity and magnetic fields, demonstrates correlation between crustal magnetic domains along the profile and the terrane affinity of the crust. This integrated interpretation indicates that a 150 km wide zone, characterized by low-grade metamorphosis and oblique thrusting of Avalonia crust over Baltica lower crust, is characteristic for the central North Sea area. The magnetic … WeiterlesenA new tectonic model for the Laurentia-Avalonia-Baltica sutures in the North Sea: A case study along MONA LISA profile 3
DOI http://dx.doi.org/10.1029/2021GL097394 Abstract Plain Language Summary Continent‐continent collisions are an important tectonic process and have controlled the formation of the modern continents. The India‐Asia collision is the best modern example and has produced both a high elevation plateau and the world’s highest mountain belts. A range of tectonic processes occurs during these collisions as the crust deforms including extrusion and perhaps crustal flow. Within these collision zones, there are locations of especially rapid uplift that have not been explained with existing geodynamic models. This paper investigates this process through a study of Gongga Shan—a mountain on the eastern edge of the Tibetan Plateau, where uplift continues at a rate of 2–3 mm per year and has formed peaks greater than 7,500 m in elevation. 3D inversion of an array of magnetotelluric data has produced a well‐constrained crustal resistivity model for the GGS area. It reveals that the GGS crust is … WeiterlesenMechanism for the Uplift of Gongga Shan in the Southeastern Tibetan Plateau Constrained by 3D Magnetotelluric Data
DOI https://doi.org/10.1038/s41598-018-29638-6 Abstract 3D and 2D seismic data reveal the base-reflection of the Quaternary in the northwestern German North Sea locally at depths of more than 1000 m. This indicates extremely fast subsidence, with a rate of up to 480 m/Ma during the Quaternary, resulting in a NNW-SSE oriented sedimentary depocentre. Distinct iceberg scour marks, identified in 3D seismic data are used to calibrate quantitative subsidence analysis and to document shallow marine conditions during the Quaternary interglacials. Previously, a number of mechanisms have been proposed to explain the Quaternary subsidence. Here we show that compaction and load-induced subsidence alone explain about 75% of the observed Quaternary subsidence. However, a certain portion of the subsidence needs additional processes to be invoked. The extensive seismic dataset interpreted here makes it possible to exclude a phase of renewed tectonic activity as the origin of the subsidence anomaly. From the orientation and extent of the depocentre, … WeiterlesenRapid Quaternary subsidence in the northwestern German North Sea
DOI http://dx.doi.org/10.1130/G37958.1 Abstract The crustal seismic velocity structure of northwestern Europe shows a low P-wave velocity zone (LVZ) in the lower crust along the Caledonian Thor suture zone (TSZ) that cannot be easily attributed to Avalonia or Baltica plates abutting the TSZ. The LVZ appears to correspond to a hitherto unrecognized crustal segment (accretionary complex) that separates Avalonia from Baltica, explaining well the absence of Avalonia further east. Consequently, the northern boundary of Avalonia is shifted ∼150 km southward. Our interpretation, based on analysis of deep seismic profiles, places the LVZ in a consistent crustal domain interpretation. A comparison with present-day examples of the Kuril and Cascadia subduction zones suggests that the LVZ separating Avalonia from Baltica is composed of remnants of the Caledonian accretionary complex. If so, the present-day geometry probably originates from pre-Variscan extension and eduction during Devonian–Carboniferous backarc extension. The reinterpretation of deep crustal zonation provides a … WeiterlesenThe Thor suture zone: From subduction to intraplate basin setting
