摘　　要：吉黑造山带其实质是天山－兴安造山带的东延部分，夹持于华北板块与西伯利亚板块之间，北部为以佳木斯地块为中心的地块群，南部为古生代陆缘褶皱带，东北部为中生代走滑拼贴的那丹哈达－比金地体。该造山带是由于晚古生代末期华北板块与北部中间地块间的陆－陆碰撞对接和中生代太平洋板块的斜向俯冲挤压形成的。二叠纪是吉黑造山带古地理、古气候和古构造变化最为显著的时期，反映在生物古地理方面的生物混生和交融也非常明显。详细研究该时期生物古地理格局与演化是解决造山带二叠纪古构造格局的关键。In fact, the Jilin and Heilongjiang orogenic belt is the eastern parts of the Tianshan and Xing’an orogenic belt, it locates in between the Huabei plate and Siberia plate The north part of the orogenic belt is composed of a group of massif; the south part is a Paleozoic folding belt; and the northeast part is Nadanhada terrane connected with the Eurasia continent in the Mesozoic The orogenic belt is formed by the collission between the Huabei plate and north middle massif in Paleozoic and the oblique thrusting collission of the pacific occean plate in the Mesozoic
