Pre-existing lithospheric weak zone and its impact on continental rifting – The Mid-Polish Trough, Central European Basin System

Together but separate: decoupled Variscan (late Carboniferous) and Alpine (Late Cretaceous – Paleogene) inversion tectonics in NW Poland

“…The study area in NW Poland is located in the region, where crystalline basement is buried very deep, to a depth exceeding 11 km, as documented by deep seismic refraction data and gravity-magnetic modelling studies (Guterch et al, 1999;Guterch and Grad, 2006;Grad and Polkowski, 2016;Mazur et al, 2021). This is also compatible with the results of deep seismic https://doi.org/10.5194/se-2021-105 Preprint.…”

Subsalt Rotliegend Sediments—A New Challenge for Geothermal Systems in Poland

“…This corresponds to the eastern extension of the Permian and Mesozoic system of epicontinental basins of Western and Central Europe-the Mid-Polish Trough (MPT) [10][11][12][13][14]. According to the newest research, the Permian-Mesozoic architecture of MPT inherited its foundations after the Ediacaran rifting phase of Rodinia, which resulted in lithosphere thinning [15,16]. The direct impulse for the MPT development was the rifting phase in the latest Carboniferous to Early Permian, which was coupled with intensive volcanic activity that was followed by post-rift thermal subsidence and the deposition of Lower Permian Rotliegend clastics and Zechstein marine deposits [17,18].…”

“…Thermal subsidence of the MPT lasted up to the Late Cretaceous, involving three main pulses in: (1) Zechstein to Olenekian; (2) Oxfordian to Kimmeridgian; and (3) the Early Cenomanian [18,19]. The final stage of the MPT evolution was Late Turonian through Paleocene compressional inversion [11][12][13][14][15]19,20]. The MPT's inversion was a widespread uplift typical for basins with thick salt sequences.…”

“…The study area in NW Poland is located in the region, where crystalline basement is buried very deep, to a depth exceeding 11 km, as documented by deep seismic refraction data and gravity-magnetic modelling studies (Guterch et al, 1999;Guterch and Grad, 2006;Grad and Polkowski, 2016;Mazur et al, 2021). This is also compatible with the results of deep seismic reflection surveying in the area adjacent to the east that documented the Caledonian orogenic front thrust over the undeformed lower Palaeozoic foreland and underlain by a lower plate that gradually descends towards the SW to a depth of at least 10 km (Krzywiec et al, 2014;cf.…”
