Abstract: Abstract Rupture behavior, one of the quantitative features of active fault, is fundamental for understanding crustal deformation mechanisms and assessing regional seismic risk. The 120-km-long Tianqiaogou-Huangyangchuan Fault (THF) is an important branch fault of the… read more here.

Abstract: 本文在对三维联片地震资料构造解析及边界断层“跃迁”构造模式的基础上，提出了南堡凹陷北边界断裂形成演化的新认识，并阐述其石油地质意义。结果表明，① 南堡凹陷在断陷阶段，北边界断层存在显著的分段性，而且随着应力场的演化，位置、性质和作用是不断变迁的；② E2s3期边界断层(古西南庄断层)控制了南堡凹陷主力烃源岩的分布，并进一步控制北部周边凸起的油气成藏；③ 提出了裂陷边界断层物源口分布的预测模式，并预测了南堡凹陷北部边界的物源口分布；④ 边界断层主控性质的“跃迁”，导致南堡凹陷拾场次凹流体势场的变化。 On the basis of structural analysis of 3D seismic data and tectonic model of boundary faults migration in Nanpu sag, new understanding of boundary fault evolution is proposed, and its… read more here.
