In the eastern part of Pannonia Depression situated in Romania, integrated
geological-geochemical and geophysical explorations (seismic, gravitational
and airborne magnetic ones) for oil land gas deposits were carried out. The
region bordered by Valea lui Mihai, Marghita, Valea Vinului, Halmeu and the
Hungarian border is particularly presented in this paper.
Seismic prospecting in correlation with boreholes information allowed the drawing
of two structural maps related to the Pannonian formation and sedimentary bottom,
respectively, In this way, fractured structures anticline and syncline zones
were discovered.
Bouguer map reflecting the density contrast between the sedimentary deposits
and the crystalline basement indicates the same structures too.
Integrated interpretation of the geophysical results presented, like seismic,
gravimetric and airborne magnetic maps point out the blocks structure of this
area.
The geophysical results were checked out by means of some deep-boreholes.
