摘要
利用Kashan地区横穿盆地的地震剖面资料, 应用平衡剖面技术恢复了Kashan地区自晚渐新世以后各个时期的构造, 认为中伊朗地区自晚始新世以来经历了弧后残留海盆地 (晚渐新世—早中新世)、前陆盆地雏型 (早中新世—中新世), 前陆盆地成型 (晚中新世—上新世) 和前陆盆地定型 (第四纪 ) 4个阶段. 现今为一典型的弧后前陆盆地, 由山前冲断褶皱带、山前凹陷带、前缘隆起带、斜坡带构成.
Based on the principles of balance profile,each epoch structure from the upper Oligocene with Kashan area seismic resource is presented.It is shown that the central basin goes through back-arc relict marine basin stage(upper Oligocene to lower Miocene ),embryonic form of foreland basin stage (lower Miocene to middle Miocene),the molding form of foreland basin stage(upper Miocene to Pliocene),the finalizing of foreland basin stage(Quaternary System),since upper Eocene.Now a typical back-arc foreland basin is shown.At the same time, the basin is composed of fold-thrust belt,lepression belt,leading edge uplift belt and slope belt.
