چکیده

Geological lineaments are an essential component of geological structure on the surface, and they are used in resource exploration for hydrocarbons, groundwater, and minerals. This study aims to extract lineaments from satellite images and magnetic data in the Zivah 1:100000 geological sheet. The lineaments were extracted using manual and automatic methods. Directional filters in different directions and hillshade technique were applied to manually extracted lineaments. Lineaments were automatically extracted using principal component analysis on the panchromatic band of Landsat 8, followed using the Segment Tracing Algorithm (STA). Magnetic data were used to extract basement faults and lineaments. The study observed that most fractures and lineaments in the region have an East-West trend and are extremely consistent in orientation with the basement faults in the Zivah area, suggesting that the systematic fault systems at the basement in the study area have been reactivated many times. The correlation between surface linear features and probable subsurface oil and gas traps (Anticlines) was also assessed, and the implication of using surface lineament and fracture analysis for delineating hydrocarbon reservoirs in the area was discussed. The highest density of faults and fractures was found in the central areas of Zivah, indicating that the areas might be a suitable bed for the accumulation of hydrocarbons. Therefore, the study recommends the use of surface lineament and fracture analysis as a cost-effective tool for hydrocarbon exploration in other parts of the basin.
