Abstract
Fractural characteristics , structural evolution characteristics and the formation mechanism of northern slope of Bamianhe area in Dongying depression have been studied .Fault distribution characteristics , activity and the evolution of northern slope in this area have been clearly illustrated .Furthermore , the structural deformation characteristic has been analyzed as well .It is showed that there were two independent systems of tectonic deforma-tion existed in Bamianhe area after the Mesozoic era .One is interaction force in the edge of the plate , the other is the traction force which was generated in the mantle diapir applying on the bottom of the lithosphere because of con -tinuous plate subduction .Therefore, the north of the Bamianhe area showed different characteristics of structural de -formation in different periods with the combination of the two tectonic forces .关键词
