山东断块地貌
|
摘要
山东境内网格状断裂发育，将山东地质体分割成相对独立的构造单元———断块．可以根据断块活动的整体性和差异性及其反映的构造地貌特征划分为二级断块地貌系统．Ⅰ级断块地貌具有较大差异，并具有不同的地貌发育史．Ⅱ级断块由于中、新生代构造活动的方式不同而具有不同的构造地貌特征．断块地貌对地震的分布具有一定的指示作用．
The geologic body of shandong Province is separated by the large faults distributing reticularly into independent portions_blocks. Two ranks of blocks can be divided through comparing the global and diverse property of block movements and block landforms. The landforms and its development history among the first rank of blocks vary greatly. The second rank of blocks have various charactaristics of tectonic landforms because of different movement fashion in Mesozoic and Cenozoic Era. The block landforms contain some information that helps to point out the distribution of earthquakes.
