摘要
本文通过重磁资料的数据处理和反演、天然地震震源的统计以及深断裂与火山活动关系的研究提出:佳木斯地体与两侧的造山带有着截然不同的地壳物质组成和构造类型,晚白垩世以来,其深部构造活动性较两侧更强。
The authors have processed the aeromagnetic and gravity data analyzed the statistics of earthquake focus, studied the relation between volcanic rock and deep fault. It is found that Jiamusi terrane is obviously different from its surrounding orogenic belts in deep structure and geophysical properties. Jiamusi terrane is more active than belts since Late Cretaceous period.
