摘　　要：吉林省地体构造的一个显著特征是在早古生代以前，伊舒断裂两侧分属两个不同的大地构造单元。西侧的构造环境与华北大陆板块北缘相似，为受古蒙古洋作用的早古生代活动陆缘，东侧为长白山－张广才岭地体添加带（也称联合地体），省内包括吉林－延边古生代增生褶皱带及辽吉台块。其中辽吉台块于新元古代到早寒武纪位于赤道附近，以后沿巨型拆离面逐渐北移，于二叠纪末沿辉发河－古桐河拼贴带，与吉林－延边古生代陆缘增生褶皱带拼贴到一起，由于陆－陆碰撞形成了金银别－四岔子复杂构造带，华力西晚期，使吉林省南北合一，拼为一体，在中生代进入了滨太平洋大陆活动阶段，由于库拉板块、太平洋板块的俯冲，消亡机制的控制，在吉林省出现了一系列火山沉积盆地。Befof the early Paleozoic era ,there is an obviously characteristic for the structure of the terrain in Jilin province,i.e,two sides of the Yishu fracture are different geotectonic units.The western tectonic setting is simillar to the northern margin of North China continentalplate,indicating a process influenced by the palaeo-Mongolia Ocean,the early Paleozoic ac-tive epicontinent eastern part is the Changbaishan-Zhangguangcailing terrain fill zone(alsocalled coalescing terrain),including Jilin-Yanbian Paleozoic accretive folded belt and Liaojiplatform block.Among them, the Liaojiplatform block lied in nearby the equator from Neo-proterozoic to early Cambrian,late,moved towards the north gradually along the megafrac-ture with the end of the Permian Huifahe-Gudonghe matching belt matched with Jilin-Yan-bian Paleozoic continental accretive folded belt in Jilin-Yanbian area resulting in formation ofthe Jinyinbie-Sicazi compliated structural belt as continent-continent collision ,late variscan,both parts(SN)were incorporated into one in Jilin province and became marginal-Pacificcontinental active stage. In Mesozoic ,the subduction of the Kula and Pacific Plates and thecontrol of consuming mechanism resulted in formation of a series of volcanic sedimentarybasin in Jilin province.
