## 7 Conclusions  
The different tensors components from the airborne gravity and aeromagnetic anomalies maps provide options in validating the subsurface of Central Luconia Province and allow for the re-evaluation of the structural orientations at distinctive depth ranges. The aeromagnetic anomalies maps capture magnetic response from the magnetic bodies, assume as the basement of Central Luconia Province. The evaluation of the aeromagnetic maps yields E-W to NNW-SSE and NWW-SEE structural trends. The NNW-SSE is striking in the same direction of the rifting faults that stretched the continental crust and relatable with regional trend preserved in Vietnam and Kalimantan. The E-W direction imaged through the magnetic anomalies is not clearly understood but could correspond to the trace of subduction of Luconia continental shelf underneath Central Borneo and might represent the southern boundary of the Palawan/Luconia crustal block. An imprinted NW-SE fault(s) is observed in first derivative aeromagnetic data, indicating of prolong growth faults that initiated at the top of magnetic basement and continues offsetting the younger sediments. The airborne gravity anomalies maps capture density contrast within the subsurface. The distribution of gravity anomalies on different depth (Z) domain reveals dominant NW-SE structural trends with auxiliary NE-SW trends. Dominant faults/lineaments trends in NW-SE orientation and are seen to offset sediments deposited during Miocene (Cycle III and younger) as proven from the seismic lines. As such, airborne gravity yields information for the shallower section whilst the aeromagnetic data facilitate information for the deeper section, particularly the magnetic bodies including the basement. Specialized depth profiles extracted from the airborne gravity provide rigorous correlation in between the airborne gravity and seismic interpretation. Gravity response on the gravity anomalies maps is equated to morphology of top carbonate within Cycle IV and V, represented by more than one seismic horizon. Long wavelength (Tz) gravity (deep markers) is associated with sediments deposited in Cycle I or Cycle II through resemblance of the morphology identified on the seismic sections parallel to the depth profiles. Comparison of the interpreted faults at various wavelengths (depths) with [51; 52] structural maps reveal similarity on the location of faults and its' NW-SE dominant orientation, those interpreted on gravity anomalies map. However, faults interpreted at deeper section as revealed by the aeromagnetic maps are not represented in any published structural maps for this area. This study concludes the airborne gravity typically effective in reflecting shallower lithologic layers and the structures which affect them within depth less than 10 km while, the aeromagnetic data reveals geometry of the geological objects in the deeper section (more than 10 km) such as basement structures and potential trace of deep subduction zone. The interpretation of aeromagnetic data is undeniably helpful in improving the geological interpretation over Central Luconia Province, the identification and isolation of the anomalies, the comparison of analyzed gravity, and aeromagnetic maps with established interpretation and finally, the grouping of the anomalies into areas zonation. As suggested, Area A (Figure 13C) is suggestive for elevated structures possibly originated from the magnetic basement of Luconia Shelf, a zone that should be consider for further investigation to understand the tectonic evolution of this area. Whilst area B focus on the priority area for any follow-up drilling program, considering Central Luconia as prolific hydrocarbon resource particularly from the Miocene limestone. Overall, interpretation structural trends on airborne gravity and aeromagnetic data had provided a new insight in re-assessing the structural trends in Central Luconia Province. It should be taken into consideration in any re-drilling program in search of new hydrocarbon prospects.
