陸邊階地Tectono - sedimentary evolution of the basin may be divided into three stages : continental margin rift, back - arc rift, and depression basin
其沉積?構造演化可劃分為三個階段:大陸邊緣裂谷、弧后裂谷和拗陷盆地。On the basis of lots of forerunners " data and my research in this thesis, i put forward that the formation and evolution of the west sichuan foreland - like basin were controlled asynchronally by thrust action of two tectonic zones ? longmen mountains and micang - daba mountains, and divided the west sichuan foreland - like basin into three evolutionary phases - - early margin foreland basin stage ( t3m - t3t ), middle foreland - like basin stage ( t3x - j3p ) and late shrinking and extinct stage ( k1 ? 2 )
在收集眾多前人資料和本論文編寫階段實際觀測研究的基礎上,提出和論證了川西類前陸盆地的形成和演化受龍門山和米倉山?大巴山兩構造帶非同步逆沖推覆作用的復合控制,並將川西類前陸盆地的構造演化劃分為三個階段:早期邊緣前陸盆地演化階段( t _ 3m ? t _ 3t ) 、中期類前陸盆地演化階段( t _ 3x ? j _ 3p ) )和晚期萎縮消亡演化階段( k _ 1 ? e _ 2 ) 。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 )
根據構造發展階段和成礦作用特點,確定本區成礦系統及組合如下: ( 1 )華北板塊西南邊緣太古宙中元古代裂解期前成礦系統:東大山鐵成礦組合,金川鎳銅成礦組合; ( 2 )柴達木板塊北緣中、新元古代裂解成礦系統:樺樹溝柳溝峽鐵成礦組合; ( 3 )加里東期活動大陸邊緣成礦系統:早期島弧裂谷成礦組合(白銀廠清水溝銅及多金屬成礦組合) ,中、晚期島弧成礦組合(紅溝蛟龍掌銅及多金屬成礦組合) ,弧后擴張盆地成礦組合(豬咀啞巴九個泉石居里銅及多金屬成礦組合) ,與俯沖作用有關的巖漿熱液成礦組合(塔爾溝小柳溝鎢成礦組合,樺樹溝柳溝峽銅成礦組合,大東溝吊大坂鉛鋅成礦組合) ,洋殼殘片成礦組合(大道爾吉鉻成礦組合,玉石溝鉻成礦組合) ; ( 4 )碰撞造山成礦系統:前陸盆地成礦組合(天鹿銅成礦組合) ,陸內造山韌性剪切成礦組合(寒山鷹咀山金成礦組合) 。On the basis of analysis on the characteristics of structural evolution, the growth of the source rocks is analyzed. in the period of mesozoic - palaeozoic, caledonian events and the evolution of hercynian - early indo - chinese cycle are experienced in two - phase marine passive continental margin and craton basin in the lower and middle yangtze region, by which stable enormous thick mesozoic - palaeozoic deposites are induced, six sets of source rocks are produced, it has a strong capacity of hydrocarbon generation
摘要通過構造演化特徵分析了海相烴源巖的發育,中、下揚子區中古生代經歷了加里東和海西早印支旋迴兩個階段的海相被動大陸邊緣和克拉通盆地演化,形成了巖性穩定的巨厚中古生界,發育了6套烴源巖,具有較強的生烴能力。分享友人
