“…Previous studies have distinguished four vein generations in the BCF, indicating four different tectonic and/or vein cementation processes. The four categories are the branched veins, the straight veins, the en-echelon vein arrays and the breccia-like veins [29][30][31][32]. The fractures are filled dominantly with calcite, anhydrite, and barite-celestine [15,[29][30][31][32].…”

“…Furthermore, a sharp decrease in the acoustic wave velocity is also observed below 400 m. This feature reflects the appearance of a rock body with significantly different rock mechanical properties, even if the lithology and the fracture geometry parameters (other than the density) do not change at this boundary. Furthermore, the presence of all four vein generations (Hrabovszki et al, 2017(Hrabovszki et al, , 2020(Hrabovszki et al, , 2022Tóth et al, 2020) along the well suggests that the entire rock column shares an identical structural evolutionary history. Konrád et al (2015) explained that the difference between the upper (0-400 m) and lower (400-915 m) segments of the rock body developed during uplift of the formation and the coincident loosening of the upper section.…”

“…The most recent essential event is the ongoing tectonic inversion of the basin . Previous studies distinguished four vein generations along the BAF-2 well that indicate multiple tectonic and/or diagenetic processes (Hrabovszki et al, 2017(Hrabovszki et al, , 2020(Hrabovszki et al, , 2022Tóth et al, 2020). The veins are classified into the following categories: branched veins, straight veins, en échelon vein arrays, and breccia-like veins.…”
