The More Basin is located on the continental margin of central Norway, between 62° to 65° North latitude and 2° West longitude to 7° East longitude. It is rich in oil and gas resources and is a key exploration area in Norway. This paper aims to investigate the gravity anomalies and structural characteristics of the More Basin in depth, and to provide guidance for oil and gas exploration in the Norwegian region, this paper compiled the data of Bouguer gravity anomalies in this area and calculated Bouguer gravity anomalies. The Bouguer gravity anomalies were processed using the sliding average method to obtain residual gravity anomalies. Based on the extreme values of gravity anomalies, the trends of anomaly belts, and the changes in gradient belts, the faults in the More Basin were identified, and the local fault structures were determined, thereby dividing the structural units in this area. The study indicates that the More Basin is characterized by four boundary faults and numerous secondary faults. The gravity anomaly features are distributed in a NE-NEE-NW direction, which can be divided into three parts from south to north. The southern faults trend northeast, the central faults trend northeast-northeast, and the northern faults trend northwest, forming three zones of gravity anomaly trend changes. The gravity anomalies exhibit alternating high and low belts, reflecting the framework of basement uplifts and depressions in the region. There are also a few northwest-trending cutting faults within the basin, which control the development of secondary structures in this area. Through the study of gravity anomalies, the geological structural characteristics of the area are clarified, providing a basis for the structural evolution and oil and gas exploration in the More Basin.
