一、沉积盆地的形成——剥蚀与沉积的对立统一持续地接受沉积的地区称为沉积盆地。沉积盆地的形成是剥蚀与沉积的对立统一;有赖于蚀积平衡面的不断变动。没有蚀源区的上升,就没有剥蚀的持续;没有沉积区的下陷,就没有沉积的持续(图1)。剥蚀与沉积的空间分异反映了地壳活动的地理景观。剥蚀与沉积的时间分异代表了地壳演化的地史变异。
First, the formation of sedimentary basins - the opposite of erosion and sedimentation Unification continues to accept the deposition of the area called the sedimentary basin. The formation of sedimentary basins is the opposite unity of denudation and sedimentation; it depends on the constantly changing balance of erosion and sedimentation. Without erosion of the source area, there is no erosion sustained; there is no deposition of sediment deposition (Figure 1). The spatial differentiation of erosion and sedimentation reflects the geographic landscape of crustal activity. The time difference between denudation and sedimentation represents the variation of geostatistics of crustal evolution.
