The South China Sea locates at the convergence center of the Eurasian Plate,the Pacific Plate and the Indo-Australia plate. The Cenozoic seafloor spreading in the South China Sea Basin is an important part of the tectonic evolution of the South China Sea that records information of the continental margin tectonic history and its impact on regional geologic evolution. Magnetic data contains abundant geological structure information from the surface to deep. This paper reports magnetic data of the South China Sea. Through the conventional processing of these magnetic data,we report general results on the regional magnetic anomalies,such as the upward continuation graph,the polar magnetic anomaly map and the magnetic anomaly partition map. The magnetic anomaly field in the South China Sea is divided into eight areas,of which the characteristics are explained,and the tectonic evolution of the South China Sea is preliminarily discussed.
