摘　　要：断陷盆地内地堑带中地层厚度减薄的现象经常发生,但对其形成原因研究较少,本文通过分析总结,把断陷盆地内地堑带中地层减薄成因分为两大类情况来进行探讨:第一类情况是断层发育之前地层出现了减薄,受后期断层活动的影响较弱;第二类情况是伴随断层的发育过程,地层受断层活动的影响导致地堑带中地层厚度减薄。通过分析本文,认为等二类情况中断层活动的影响是导致断陷盆地内地堑带中地层减薄的主要因素。Fault basin inland rift belt formation thicknessthinning is often happened, but the formation reasons of less,through analyzing and summarizing, this article, the rift grabeninland basin formation reduced thin formation is divided into twokinds of situation to carry on the discussion ： the first category isfault development prior to the formation of the thinning of theweaker effect of fault activity in the late ; the second category isaccompanied by the developmental process of the fault and formationby the influence of fault activity leads to the graben formationthickness thinning. Through the analysis, this paper arguesthat the second category interrupt effects of active layer is infaulted graben inland basin formation reduction thin main factors.
