Tectonics is a crucial research field, holding a key-role in applied geology, as it provides qualitative and quantitative information, which is decisive in various types of studies. In particular, these studies are related to:
- Geological Hazards: Natural disasters are linked to tectonic processes; their most important outcome is the earthquakes, as well as other secondary effects such as volcanic eruptions, landslides, and tsunamis. In all the above cases, performing tectonic analysis is essential to understand the nature of these hazards and to mitigate their impact on human settlements and infrastructure.
- Groundwater Resources: The active tectonics have important effects on aquifer creation and groundwater ﬂow. The detailed determination of tectonic structures is necessary to locate and manage these resources for human consumption and agriculture.
- Geotechnical Engineering: Tectonic activity impacts the rock and soil stability. Additionally, the importance of structural geology in slopes, foundations for buildings, and pavements have been recognized. However, the integration of structural geology mapping and theory in all stages of engineering projects remains a challenge.
- Mineral and Energy Resources: Tectonic movements form geological structures that trap and concentrate mineral and energy resources such as oil, gas, coal, and precious metals. Tectonic studies are important as guides for economic geologists searching for fuels and ore deposits of metallic and nonmetallic resources.

Abstract: Caves serve as time capsules, preserving significant markers of tectonic activity and offering insights into the geological history. Fault geometries and past activations found in caves can be correlated with known deformational events in the broader area, temporal delimiting the speleogenesis. More specifically cave passage formation is suggested to be affected by the regional stress-field. Asprorema Cave in Northern Greece, is a typical example of a fracture guided cave, with passage geometry influenced by relative sidewall movements, revealing these discontinuities as faults. This study constructs the timeframe and conceptual model of speleogenesis in relation to tectonic events, geomorphological evolution, and hydrological zones and verifies its relation to the stress-field. Active tectonics, mineralogy, and cave geomorphology are investigated. Results suggest syntectonic speleogenesis under phreatic and epiphreatic conditions. The absence of corrosion on fault slip surfaces implies recent activations post cave's shift to the vadose zone. Structural analysis identifies three main neotectonic phases: NNW-SSE striking faults (oldest group of structures), NE-SW striking faults with dextral strike-slip movement (post-middle Miocene), and NE-SW striking normal faults indicating extensional stress-regime (Quartenary). The last two phases affect cave passage shape causing wall displacement, highlighting passage formation along discontinuities perpendicular to the horizontal minimum stress axis.
