摘要: 华南沿海地区,发育3组不同方向的断裂构造。以北东~北北东向的断裂规模最大,地表迹象最明显;以北东东~东西向断裂切割最深,发育历史最长;而以北西~北西西向断裂的新生性和近期活动性最显着。研究结果表明,上述3组断裂构造的特征,在宏观表征和显微构造特点方面都有表现,说明各组断裂都有各自类同的形成、发育过程,并受控于类似的构造力源,它们的特征在一定程度上反映了地壳运动的演变史。

Abstract: Developed along the coast of South China have been three sets of active fault zones,in whichthe NE~NNE trending faults are of the largest scale,with their surficial manifestation most evident and with the ENE~EW trending faults cutting most deeply and the developing historylongest,as well as with their growth and activity most evident for the NW~WNW trendingfaults.The resuhlt indicates that the characteristics of all faults mentioned above are in evidence inmacro~microtectonics,suggesting that the faults are of similar formations and developing history and controled by similar sources of tectonic forces.Their characteristics are to some extentrepresentative of the evolutions of the crustal motion.
