本文通过对１９９１年“海洋四号”船在南极布兰斯菲尔德海域所采集的地球物理资料的分析解释，指出：区内重磁异常反映为北东向条带状展布，从北向南呈高—低—高带相间，每一带内也有波状起伏，地震反射层展布及厚薄变化也有相应类似特征。由此揭示出区内地质构造特征及隆坳展布格局。对布兰斯菲尔德盆地发展演变与断裂、岩浆活动、地壳拉伸、地壳深部物质变动及板块构造运动等因素的关系作了尝试性的探讨
In this paper, by analyzing and analyzing the geophysical data of 1991 “Ocean IV” ship in Bransfield, Antarctica, it is pointed out that the anomaly of heavy and medium magnetic anomalies in the area is reflected as a northerly banded distribution extending from north to south High-low-high-band phase, also have wavy in each zone, seismic reflection layer distribution and thickness changes have similar characteristics. This reveals the geological structure of the region and the col extended distribution pattern. A tentative discussion is made on the relationship between evolution and fracture, magmatic activity, crustal extension, deep crustal material changes and tectonic movement in the Bransfield Basin
