华南沿海主要活动断裂带的比较构造研究

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著。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

A COMPARATIVE STUDY OF MAIN ACTIVE FAULT ZONES ALONG THE COAST OF SOUTH CHINA

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 evi-dent 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 histo-ry and controled by similar sources of tectonic forces.Their characteristics are to some extentrepresentative of the evolutions of the crustal motion
