| 摘要 | Based on the interpretation of seismic profiles, an ancient uplift belt was distinguished along the northern margin of South China Sea. This belt is striking in northeastern direction and about 550 km in length and 60 km in width. This belt is coincided well in shape with a high positive magnetic anomaly zone on the northern margin of South China Sea. So, the paper believed that this ancient uplift belt is the origin of the high positive magnetic zone. Dongsha ancient uplift belt was a subduction related arc belt. Due to the subduction, the magma intrusion happened under the arc belt. And due to a short duration of the subduction, the intrusion only happened at the deeper part of the arc belt. So the magma accumulated and solided at the deeper part of the arc belt and acquired high positive magnetic.; Based on the interpretation of seismic profiles, an ancient uplift belt was distinguished along the northern margin of South China Sea.
