Abstract

Abstract

Nansha region is an important part of our country, with great potential for hydrocarbon resources and scientific researches.In order to analyze and compare the basins' structure as well as the sedimentary history systematically, we interprete most of the seismic profiles we have to carry out the stratigraphic correlation between Wan'an, Zengmu (Great Sarawak), Beikang, Nanweixi and Liyue basin.It is found that the stratigraphy are divided into three tectonic periods and four stages, divided by rifting unconformity (T_g), breakup unconformity (T₆₀ or T₄₀), and rifting-depressing unconformity (T₄₀ or T₃₂).The lower tectonic periods are composed of Mesozoic strata, distributed discontinuously, thicker in the Liyue basin and beneath uplift.It's the pre-kinematic sequence.The middle tectonic period is separated into rifting stage in the lower part and rifting-depressing stage in the upper part by T₄₀ in Wan'an and Zengmu basin, and by T₆₀ in Beikang, Nanweixi and Liyue basin.The sedimentation in the rifting-depressing stage may be caused by the drift of the Nansha block.The sequence after T₄₀ (or T₃₂) belongs to depressing stage.According to the rotation, erosion and fold structure, there is a collision event around Middle Miocene (T₄₀), which is especially obvious in Beikang-Nanweixi basin.Besides the folding wave on the surface, the lens-shaped Early Miocene sequence accompanied with newly formed shear faults between T₆₀ and T₄₀ showed a compressive moment around T₄₀, furthermore the Middle Miocene sequence (T₄₀—T₃₂) appear draping with thin top and thick wing.We suppose that the Nansha block collided with Borneo at this time.Relative to the northern continental margin, Zengmu seems much similar with Yinggehai basin, Beikang-Nanweixi basin seems to be conjugate with Qiongdongnan and Zhongjiannan.Liyue basin should be conjugate with Zhongsha uplift by SW sub sea basin.This conjugate pattern is consistent with the phenomena that T₆₀ is the breakup unconformity.
