Abstract: To study the gravity and magnetic field and tectonic features of the Greenland-Iceland-Faroe Ridge and adjacent areas in the Arctic region, the data from the Global Gravity Database V29, ship gravity anomaly, the third edition of the Earth Magnetic Anomaly Grid at 2 Arc Minute Resolution Version 3, and Aviation Magnetic Measurement were collected and analyzed. The magnetic anomaly by reduction to the pole was obtained by variable latitude polarization, and then the potential field edge was recognized. The free-air gravity anomaly and magnetization poles local anomalies were calculated based on the sliding average method. Combined with available studies, the features of the regional fault structure framework of the Greenland-Iceland-Faroe Ridge and adjacent areas were analyzed and 7 major faults were identified. These faults have played an important role in controlling the uplift framework, basement structure and the properties. Based on the major faults, 8 regional tectonic units were divided, including the Greenland Plate, the Kolbeinsey ridge, the Jan Mayen microcontinent, the east Jan Mayen deep sea basin, the Greenland-Iceland-Faroe complex structural belt, the Rekjanes ridge, the Aegir ridge, and the Faroe-Mainland tectonic belt, providing the geological and geophysical data for future geological exploration in the Arctic region.
