碳酸盐岩振动液化地震序列
|
摘要
新建立的振动液化地震序列系碳酸盐软沉积物中的强地震事件记录,包括地震液化阶段产生的泄水脉、液化变形;液化停止后的地面下沉构造;地震引起的津浪丘状层与浊积岩等序列单元。这个序列来自大区域的野外实践总结,反映了一次强地震事件的全过程,并在理论上得到统一的解释。序列将为野外地质学家在碳酸盐层中识别事件提供对比的标准。根据振动液化地震记录,本文首次提出古郯庐带概念,并对其地质意义进行了初步讨论。
On the basis of the records of strong seismic events taking place in soft carbonate sediments, a new seismic sequence system of vibrational liquefaction is established, which consists of a series of units, such as escaped structure of micrite veins and liqusfied deformation formed in the period of seismic liquefaction, land subsidence structure after liquefaction, tsunamic hummocky and turbidite produced by seismic events. This sequence is a generalization and summation of field observation in vast areas, which shows the whole process of a strong seismic event and provides an unified theoretical explanation.The pattern of the seismic sequences by vibrational liquefaction enriches the research on event stratigraphy and provides one of correlation standards for geolo- gists in the field to discriminate events in carbonate sequences.Based on the pattern of seismic sequences by vibrational liquefaction, a NNE palaeo-seismic zone (700Ma. B.P.), here named the Palaeo-Tanlu (Tangcheng-Lujiang) Zone, may be distinguished in carbonate sequences in the Sinian System in the eastern part of Sino-Korean Platform, The formation of the Palaeo-Tanlu Zone caused the separation of the Sino-Korean Platform into two blocks, the Jiaoliao (Shan-dong-Liaoning)-Korean block and the North China block, each having its own specific geological history during early to middle Palaeozoic times.
