摘要
莺歌海—宋红盆地位于越南东海岸和海南岛之间,由红河断裂带控制,形成了具有独特的走滑拉张构造特征的新生代盆地,使断裂东西两侧具有不同的构造特征.以往我国对盆地的研究主要集中在盆地东部,而盆地周边国家的研究主要集中在盆地的西部,缺乏横跨整个莺歌海—宋红盆地的地震剖面和遍布全盆地的测井资料,因此对整个盆地的构造特征和深部地壳结构研究相对较为薄弱.本文利用CCOP-ICB中越跨国合作项目提供的横跨整个盆地的地震剖面,并结合1′×1′卫星测高重力异常研究了莺歌海—宋红盆地的整体构造特征,根据断裂运动特征,结合由卫星测高重力异常计算出的布格重力异常,识别了盆地内部11个构造单元.并以地震剖面解释和盆地内丰富的测井资料作为约束,利用基于频率域Parker算法的密度界面反演算法,获得了盆地基底和莫霍面埋深,并以此为基础,以一条横跨盆地主体的中越联合地震剖面的地震解释为初始模型,利用综合地球物理反演技术,探讨了其深部地壳结构.
The Yinggehai-Song Hong Basin lying to Vietnam land coast and the west of Hainan Island is a Cenozoic basin with strike-slip and pull-apart component and unique geologic characteristics.The formation of the basin is controlled by the Red River fault zone and geologic characteristics difference between both sides of the fault.Previous studies of the basin in China are concentrated in the eastern part of it,we lack of seismic survey lines and log data across the basin.Therefore,studies on the tectonic characteristics of the whole basin and deep crustal structure are relatively weak.The paper studied tectonic characteristics of the whole basin the using seismic profiles which across the whole basin provided by the CCOPICB transnational cooperation project and satellite altimetry gravity anomaly with 1′×1′precision.The basin is divided into11 tectonic elements according to the characteristics of faults' movement and combined with Bouguer gravity anomaly calculated from satellite altimetry gravity anomaly.Besides that,we inversed the basement and Moho depth of the basin constraint on interpretation results of seismic profiles and log data.And then,we discussed the deep crustal structure of the basin based on the technology of comprehensive geophysical inversion.
