摘　　要：对Garmsar区块各时期、各层段的构造演化特征分析得出:晚渐新世一中新世Qom组沉积末发生的一幕挤压构造活动在Garmsar地区相对比较微弱,盆地内部有微弱的褶皱形变,大部分地区表现为整一接触关系。晚中新世Garmsar地区的构造活动不是很强烈,该段沉积期间发生的挤压构造运动已经开始控制Kuh-i-Gatchab构造的沉积,即断层及褶皱构造已经形成雏形。第四系以后发生了一次强烈的构造运动,尤其Alborz造山带地层抬升幅度较大,此Kuh-i-Gatchab背斜基本定型。To the Garmsar sub--area various times, various stratigraphic intervals structure evolution characteristic analysis obtains： A late oligocene miocene Qom group at the end of deposition occurs an compressional structure movement in Garmsar area relative quite weak, the basin interior has the weak fold deformation, majority of local display conformity contact relations. The late miocene Garmsar area structure activity is not very intense, this section of deposition period occurs the compressional structure movement already started to control the deposition of the Kuh--i--Gatchab structure,namely the fault and the fold structure already formed the embryonic form. Quaternary will be later has had an intense tectonic movement, the Alborz orogenic zone stratum lifting scope was especially big, this Kuh--i--Gatchab anticline basic stereotypia.
