【摘要】 作为走滑拉分盆地内的一种扭动构造，花状构造的最基本特征是近直立的基底扭断裂向上分叉撒开。研究内容大致包括构造确认、特征分析、平面分布规律及成因分析等，研究的基本思路是构造地质与地震地质相结合。其中，扭断裂的鉴定是花状构造确认的关键。更多还原

【Abstract】 The nower structure develops in strike-slip or pull-apart basin. As a type of wrench structure, its most essential charactet is that wrench fault involming basement is steeply dop ping and scatters or spreaels upwards. This research includes identification, characteristics,distribution of flower structure, and itos developing cause. It is necessary to combine structural geology with seismic giology. Identification of wrench fault is the key to study flower structures.更多还原
