Back-stripping (also back stripping or backstripping) is a geophysical analysis technique used on sedimentary rock sequences. It is used to quantitatively estimate the depth that the basement would be in the absence of sediment and water loading. This depth provides a measure of the unknown tectonic driving forces that are responsible for basin formation (otherwise known as tectonic subsidence or uplift). By comparing backstripped curves to theoretical curves for basin subsidence and uplift it is possible to deduce information on the basin forming mechanisms.

| - 回剝（英語：back stripping)是一種地球物理分析技術，用于根據沉積岩層序資料，估計沉積盆地基底所受到的由構造運動的沉降。 通常沉積盆地的基底受兩種因素下降，以便提供沉積空間。構造運動及負荷沉積物和水的重力。囘剝技術就是排除沉積物和水的影響，導出因構造運動而形成的盆地基底沉降歷史。在典型情況下，沉積盆地從邊緣到中心加深，沉積物也隨之增厚。通過一層地層厚度的消除（剝離）后, 將下一層頂界面回復到同一個基準面。這時的基底深度就代表當時的基地構造形狀。通過連續地層層層的剝離，盆地基底的加深歷史就可以反向描述。從而獲得有關其構造起源的線索。更完整的分析必須考慮到沉積厚度被壓實的量 。 (zh)

| - Back-stripping (also back stripping or backstripping) is a geophysical analysis technique used on sedimentary rock sequences. It is used to quantitatively estimate the depth that the basement would be in the absence of sediment and water loading. This depth provides a measure of the unknown tectonic driving forces that are responsible for basin formation (otherwise known as tectonic subsidence or uplift). By comparing backstripped curves to theoretical curves for basin subsidence and uplift it is possible to deduce information on the basin forming mechanisms. The technique developed by Watts & Ryan in 1976 allows for the recovery of the basement subsidence and uplift history in the absence of sediment and water loading and, therefore isolate the contribution from the tectonic forces responsible for the formation of a rift basin. It is a method by which successive layers of basin fill sediment are "stripped off" the total stratigraphy during analysis of that basin's history. In a typical scenario, a sedimentary basin deepens away from a marginal flexure, and the accompanying isochronous strata typically thicken basinward. By isolating the isochronous packages one-by-one, these can be "peeled off" or backstripped - and the lower bounding surface rotated upward to a datum. By successively backstripping isochrons, the basin's deepening history can be plotted in reverse, leading to clues as to its tectonic or isostatic origin. A more complete analysis uses decompaction of the remaining sequence following each stage of the back-stripping. This takes into account the amount of compaction caused by the loading of the later layers and allows a better estimation of the depositional thickness of the remaining layers and the variation of water depth with time.
