| 摘 要： | 珠江三角洲地区断裂比较发育 ,晚第四纪以来的活动方式皆具有垂直差异运动特征 ,且大多数都呈隐伏状态。文中在对三角洲发育阶段分析的基础上 ,利用已有钻孔资料 ,沿断裂两侧寻找位置相互靠近、且能揭露出时代和堆积环境相同的地层层位的一对或多对钻孔进行对比。根据断裂两侧相同层位现今所处海拔高度的差异确定它们沉积以来的垂直位移量 ,再根据该层位的测年数据计算断裂的垂直位移速率。共计算了 5条断裂晚第四纪以来的垂直位移速率 ,位移速率值为 0 14～0 4 7mm/a

| Abstract: | Fault structures are well developed in the Zhujiang Delta area. They can be classified into NW , NE and E W trending groups, most of which display distinct features of vertical differential movement. Since most of the faults are buried and their activities are relatively weak, the evidence of vertical dislocation are difficult to be identified directly in the field, and hence the amount of displacement along the faults can not be measured. Fortunately, a large number of drill holes have been drilled du |
