南海及邻区莫霍面深度分布特征及其与各构造单元的关系
|
摘要
为了研究南海及邻区莫霍面分布特征及其与边缘海盆、海沟、岛弧、新生代沉积盆地的关系等构造单元的关系,本文通过对研究区的空间重力异常数据进行全布格改正,得到研究区内的布格重力异常,并以近年来的声纳浮标探测与海底地震仪探测剖面所得到的莫霍面深度资料为控制点采用三维带控制点界面反演方法得到了研究区的莫霍面深度图和地壳厚度图.本文通过已有的地震剖面和研究区内9条剖面的莫霍面分布特征与各个构造单元的关系进行统计分析,总结出研究区各构造单元莫霍面的形态、走向、梯度和地壳性质,并绘制了研究区沟-弧-盆体系构造简图.本文所得到的结果和认识对研究区内进一步的构造特征、地质地球物理调查、岩石圈的研究以及油气预测有重要意义.
For the purpose of studying the distribution characteristics of Moho and its relation with the tectonic units such as marginal basins,trenchs,island arcs and cenozoic sedimentary basins in South China Sea and adjacent areas,we firstly do the complete Bouguer correction for the spatial gravity anomaly and get the Bouguer gravity anomaly of the study area.Then,we obtain the Moho depth and the crustal thickness of the study area used the method of 3D interface inversion with the control points which are from the achievements of sonobuoy measurement and OBS profiles in recent years.In this paper,we summarizes the relief,trend,gradient of Moho and crustal nature in the study area by the statistical analysis for the known seismic profiles and 9 profiles planed by us.Finally,we draw the diagram of the trench,island arc.back-arc basin system in the study area.The results of the studies are important to further research of tectonic characteristics,oil and gas prediction,lithosphere and geological and geophysical survey.
