The Ţicău area (NW Romania) is part of the collisional zone between the Tisza and Dacia mega-units. Imaging of Ţicău area's subsurface geological structure will contribute to the understanding of the processes, which controlled its tectonic evolution. Analysis of outcrops provides accurate information for the building of kinematic sections used to explain the small-scale deformations of sedimentary formations, such as those developed south of the Ţicău mountains. Imaging of large-scale deformations requires analysis of data recorded and/or measured over a wider area. We use Seismic Interferometry by cross-correlation on ambient noise recorded along with a line located north of the Ţicău mountains. The passive seismic section obtained after virtual body-wave reflections processing displays folded and faulted Paleogene formations, which are in good agreement with the observations on outcrops found to the south of the Ţicău mountains. The active-source data recorded along with the same line are too noisy for interpretation.
