闽东滨海断裂带活动特征研究
|
摘要
本文根据2006年在福建近海开展的多道地震的勘探成果,结合该区历史沉积资料,探讨闽东滨海海底断裂构造的分布特征,推断其新近活动时期为中新世晚期—上新世初期,并以遥感卫片为辅助手段,分析沿岸线性构造与滨海断裂之间的关系.航天遥感技术和卫片的采用,扩大了观察地质构造的视域和深度,弥补了野外地质观察的局限性,而物探、钻孔等工程和探测技术在本文中则为了解海底断层结构、规模提供了重要佐证,判断该断裂已达大断裂的规模.
Based on data from several seismic prospecting in offshore Fujian Province in 2006 and data from historical records collected in this area,this paper discusses the distribution characteristics of submarine offset structure in East Fujian coast area.It is inferred that the recent active period in this area can date back to the late Miocene and early Pliocene.Moreover,with remote sensing satellite photos this paper tries to analyze the relationship between costal linear structure and offshore fracture.With the help of space remote sensing and satellite photos,which pile up with many geological observations in the field,people can probe much detailed into the geological structures.Besides,the application of geophysical exploration and drilling technology produces important evidences for the understanding of submarine offset structure and scale in this survey.It shows that the fracture has spread to a large scale.
