摘要
叠合盆地中剥蚀地层厚度的恢复对沉积盆地的埋藏史、构造演化史及热史研究有十分重要的意义。目前计算剥蚀厚度的方法较多,但都存在局限性。通过对比发现,在结合其他方法的研究成果基础上,用地震资料在区域上展开的地震地层综合法在叠合盆地剥蚀厚度的恢复中具有较好的效果。运用该方法对阿克库勒凸起中上奥陶统的剥蚀地层厚度进行了计算,结果表明,中上奥陶统在该区的剥蚀厚度为0～610m.
Denudation is ubiquitous in superposition basin, and it is important for sedimentary basin study in buried history, tectonic evolution history and thermal history to choose the most proper method for calculation of resuming eroded thickness. Considering the localization of each method available, Ibis paper presents the seismie-stratigraphic approach to do it and better results can he gained. The case study from application of this approach to the eroded thickness calctulation of Middle-Upper Ordovician in Aekule swell in Tarim basin shows that its eroded thickness shouhl be about 0-610 m.
