摘要: 利用三维地震资料的构造解析和方差体切片,对琼东南盆地宝岛变换带的三维结构进行了解剖,揭示该变换带具有 “结构复杂”、“多个段落”、“多期活动”、“复式位移传递”等方面的特征。在此基础上,指出裂陷盆地存在比经典变换带更为复杂的变换带类型——复式变换构造带,并结合经典变换带的分类,提出了裂陷盆地变换构造带新的分类方案。最后,提出了裂陷盆地变换构造的两种成因类型:“先存构造活动型”(宝岛型)和“先存构造控制型”(Morley型)。

Abstract: 3D structure of Baodao transfer structure zone of the Qiongdongnan Basin was characterized by using structural interpretation and variance cube slices of 3D seismic data.This transfer structure features in “complex structure”,“multiple segments”,“multi-stage activities” and “Compound displacement transfer”.On this basis,it is proposed that more complicated transfer zone(compound transfer zones)exists in rift basin were proposed.Combining with the classic classification of transfer zone,a new classification scheme of transfer structure zones in rift basin was proposed.Furthermore,two genetic types of “pre-existing fabric activation type”(Baodao type) and “pre-existing fabric controlling type”(Morley type)were suggested.

Key words: pre-existing fabric, transfer structure, transfer fault, transfer zone, Qiongdongnan Basin
