Abstract: From 1987-1994, the South China Sea Institute of Oceanology, Academia Sinica of China, made two comprehensive geophysical surveys in the Nansha islands and surrounding areas with the research vessel “Shi Yan 2” where 14,000 km magnetic measurements were made. Based on the data collected from 1987-1992, together with the data obtained recently, characteristics of the magnetic anomaly in the Nansha islands and surrounding areas were studied and analysed. The magnetic anomaly data was also processed. Based on the upper and lower surface of the magnetic basement, the relationships between the magnetic anomaly, magnetosphere structure and oil and gas basins of this region were analysed.
