Macromorphologically, the study area in Pannonian Croatia is basically a mountain-and-basin region. Geologically, it is on the W border of the Pannonian Basin, in contact with Forealpian structures. Special importance is rendered to tectonic
movements in the origin of geological and geomorphological features. Various types of structures have been selected for study and recognised as particular types of morphostructure. Examples of relief properties suggest a relationship between orography
, geological structure and faults. The consequences of extension, compression and transgression, especially along transcurrent faults are investigated.
