摘要

Tappeh Pitti背斜为中伊朗盆地Garmsar区块内地表最完整的背斜构造。通过对Tappeh Pitti背斜地震剖面的精细解释及其形成演化和形成机理等方面的分析和探讨,认为Tappeh Pitti背斜具有深浅不协调的特点,即在浅层表现为一鸡蛋型完整背斜而在深层却表现为一向西倾伏的鼻状构造;Tappeh Pitti背斜定型于第四纪,其成因与上红组M2段内层面滑脱断层有关。
Tappeh Pitti Anticline,located at Garmsar block inc entral Iran Basin,is the most complete anticlinal structure.Int his study,a detailed interpretation to seismic profile of the anticline is carried out,and both its forming evolution and mechanisma re also analyzed.It is considered that this anticline is characterized by an incoordination,which the shallow appears ane gg-shaped and whole anticline whereas the deep appears aw est-dipping nose structure,respectively.In addition,results illustrate that the anticline was formed at Quaternary and geneticallym ight be related to the detachment fault within strata in M2 Membr of Red Formation.
