1. The structural evolution of Bükkalja based on field works and seismic section analysis

ELTE, Dept. of Physical and Applied Geology

2. The revelation of main structural evolution phases of Bükkalja focusing on Miocene period
The comparison of field works and seismic section analysis in fault identification
The creation of some structural sketch models from Late Oligocene to Late Miocene period

3. Applied methods
Field works (76 measurement points, cca structural data: striae, joints,
stylolites, deformation bands, gravel cracks, fissures, foliation, folds)
Stress field analysis (115 stress fields), fault statistics
Fault identification based on morphology, Bouguer gravitational and
geological maps
Wells studying
2D seismic section analysis (76 sections were interpreted) of Vatta Maklár Through
horizons picking (Top Mesozoic, Top Paleogene, Base Pannonian) fault
interpretation (fault correlation, fault polygons)
Faults identified by seismic section analysis were compared with Bouguer
gravitational and geological maps, stress fields and measurements of quarries found
just above or very close to fault polygons
