Rola pamięci litosferycznej w przestrzennym i czasowym umiejscowieniu deformacji wewnątrzpłytowych - badanie wgłębnej struktury strefy uskokowej Grójca w oparciu o anomalie pól potencjalnych i dane sejsmiczne

The Grójec Fault is one of the most conspicuous geophysical discontinuities within the SW margin of the Eastern European Craton (EEC) that is imaged by magnetotelluric and gravity data. This discontinuity correlates with a fault whose Late Cretaceous activity has been documented since the eighties. Earlier history of the Grójec Fault is poorly studied, however, the subsurface information available (borehole and seismic data) suggests activity of the fault already in the Precambrian.

Magnetotelluric and geomagnetic deep sounding supported by analysis of gravimetric and magnetic anomalies and seismic data are used to study the lithospheric structure in the Grójec Fault Zone. Our research will allow geophysical imaging of an intracontinental fault zone that extends from the base of crust to shallow Cenozoic sediments, with a unique worldwide record of activity from the Precambrian to Paleogene.
