摘要
新编中国南部海区及邻域1:100万地质地球物理系列图与"中国东部海区及邻域1:100万地质地球物理系列图"为一套系列成果,包括空间重力异常图、布格重力异常图、磁力异常图、沉积物分布图和区域构造图五种专题图件.这五种图件采用统一的地理底图,根据不同专题的技术要求,利用当代先进的编图方法和成图技术,综合已有资料、前人成果和近年实测数据编制而成.本文在充分阅读新编图件的基础上,对中国南部海区的地球物理场特征、沉积物分布规律、区域构造演化等基本地学特征进行了分析研究,加强了对南部海区地质、地球物理特征的认识.
The 1：100 million geophysical maps sets,in Southern China Sea,was grouped by free air gravity anomalies maps,bouguer gravity anomalies maps,magnetic anomalies maps,surface sediment distributing maps,and regional structuring maps.The maps sets of geological and geophysical of both eastern China seas and southern China seas were a series of achievements.All of the five thematic maps used the same geographic base and map compilation thought,and used the most advanced drawing method and chart stacking technology.The map data include existing data,previous research results and recent measured data.The paper analyzed the new map sets,researched geo-science character of southern China sea,such an geophysical field characteristics,sediment distribution and regional tectonic evolution.It was helpful for further understanding the characteristics of geological structure in Southern China Sea.
