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
