自中新生代以來，岡底斯構造帶經歷了洋殼俯沖、弧陸碰撞、陸內俯沖-碰撞、走滑和塊段隆升的多階段構造演化歷程，形成了由北向南七個二級構造單元，即岷千日白堊紀殘余海盆、阿索構造混雜巖帶、它日錯?文部燕山期巖漿弧帶、措勤?幫多晚古生代復合弧后盆地、江讓?格爾耿斷隆、岡底斯?查孜喜馬拉雅期巖漿弧帶、日喀則?安巴弧前盆地。In the light of tectonic evolution stage and metallogenesis, these metallogenic system ( assemblage ) could be classified as follows : ( 1 ) the pre - divergent metallogenic system in the southwest margin of north china paleocontinent in the archean - meso proterozoic : dongdashan iron, jinchuan nickel - copper. ( 2 ) the divergent metallogenic system in the northern margin of the qaidam paleoplate in the middle - late proterozoic : huashugou - liugouxia iron. ( 3 ) the metallogenic system in the active margin in the early paleozoic : the metallogenic assemblage in the island arc - rift in the early stage ( baiyinchang - qingshuigou copper - polymetallic ) ; the metallogenic assemblage in island arc in the middle - late stage ( honggou - jiaolongzhang copper - polymetallic ) ; the back - arc extensional basin ( zhuzhuiyaba - jiugequan - shijuli copper ) ; the metallogenic assemblage in connection with subduction and magmatic - hydatogenesis ( taergou - xiaoliugou wolfram ; huashugou - liugouxia copper ; dadonggou - diaodaban lead - zinc ) ; the metallogenic assemblage is related to the oceanic crustal shards ( dadaoerji chromite ; yushigou chromite ). ( 4 ) the metallogenic system has something to do with collision - type orogeny : the metallogenic assemblage in foreland basin ( tianlu copper ) ; the metallogenic assemblage with the intracontinental orogeny and ductile shear ( hanshan - yingzhuishan gold )

摘要通過對鄂爾多斯盆地西緣北段沉降史的分析可知，晚三疊世白堊紀，由於中三疊世巴顏喀拉地體、晚三疊世羌塘地體、中晚侏羅世拉薩地塊、白堊紀岡底斯地體連續向北增生、碰撞以及燕山期伊佐奈岐板塊的俯沖，盆地西緣北段的響應顯示為陸內前陸盆地的特徵。Daqing region is situated in the middle - north of songlao basin, the tectonics inducing earthquakes in this region are mainly influenced by the pressing force of the pacific plate to the northeast asian continent, there were 6 earthquakes, which ms were not less than 6. 8 among the earthquake records in the history, and the most dangerous earthquake occurred in 1119
大慶地區位於松遼-張廣才嶺構造區松遼盆地的中北部，發震構造主要受太平洋板塊向東北亞大陸俯沖產生的推擠作用力的影響。自有地震記錄以來，重點工作區內共記錄到ms 4 . 7級地震6次，其中6級以上地震2次， 4 . 7 ms 6級地震4次，最大地震是1119年扶餘6 . 8級地震。分享友人
