俯沖造山帶
英文
subduction orogenic belt-
Chagan sag is a secondary tectonic unit in chagandelesu depression, northeastern yingen - eji ' naqi basin, and the basement of the basin is a paleozoic fold belt of continental margin or island arc at the connection region of north china plate * tarim plate and kazakstan plate, with the character of erogenic belt. in working area and its adjacent area, the forming tectonic setting of indosinian intrusion was that orogenic belt pressed strongly, intracontinental subduction ; that of early yanshan movement epoch was the stress field transferred from compression to extension meanwhile the incrassate crust of orogenic zone turned to extensional collapse ; and that of early cretaceous volcanics was that the area structure extensional collapse further more during the post period of orogenic phase
查干凹陷屬于銀根?額濟納旗盆地東北端查干德勒蘇坳陷內的一個次級構造單元,其盆地基底為古生代時期華北板塊、哈薩克斯坦板塊和塔里木板塊交接部位形成的陸緣或島弧褶皺帶,具有古生代造山帶的性質。研究區及鄰區印支期侵入巖形成於造山帶強烈擠壓陸內俯沖的構造環境;燕山早期侵入巖形成於由擠壓轉向拉伸、造山帶的增厚陸殼開始發生伸展垮塌的構造環境;早白堊世火山巖形成於造山期后進一步發生伸展垮塌的區域構造環境。In this case during paleozoic, nearly east west trending arc structures resulted from the interaction between china plate and siberian plate. in mesozoic the westward subduction of kula - pacific plate under the china continental plate resulted in the nne and ne trend structures ( duimadao fault, diaoyudao fault, okinawa fault, uplifts belts and subsidence belts ) as well as volcano - magmatic belts in eastern of china plate
本文所涉及近東西向展布的弧形構造形成於古生代時期中國板塊與西伯利亞板塊的碰撞帶,而在中生代,中國板塊下的kula - pacific板塊向西俯沖導致了北北東向和北東向構造(如duimadao斷層、 diaoyudao斷層、 okinawa斷層、隆起帶和沉降帶)以及位於中國板塊東部的火山巖漿帶。The temporal and spatial evolution of orogenic granitic belt shows certain kind of regularities : subduction type granites collision type granites extensional type granites
造山帶花崗巖的時空演變規律是:俯沖型碰撞型伸展型。The three orogenic belts of sanjiang, qinling and xingan - mongolia developed in china from south to north, not only record the perfect history of the paleo - asia plates evolutionary process, and also reflect the effects of pacific plate subducting and indian - asia continent collision on continental margin and intern, especially these orogenic belts have experienced the main processes and metallogeny during the collision to post - collision and
我國從南往北發育的三江造山帶、秦嶺造山帶和興蒙造山帶,記錄了古板塊演化旋迴及其成礦作用的完整歷史,也疊加了中新生代太平洋板塊俯沖和印度板塊碰撞導致的大陸邊緣及陸內效應的信息。During this evolution, seven second - order tectonic units were formed ; from north to south are the mingqianri cretaceous residual sea basin, the arsuo tectonic melange zone, the taricuo - wenbu yenshan magmatic arc belt, the cuoqin - bangduo late paleozoic composite back - arc basin, the jiangrang - geerdi faulted uplift, the gangdise - chazi himalayan magmatic arc belt, and the xigaze - anba fore - arc basin. these units comprise important parts of a poly - arc - basin system and exhibit evolutional features of mesozoic to cenozoic arc - basin systems. mosaic pattern of these tectonic units delineates the lithosphere coupling processes of the gangdise tectonic belt under mechanisms such as back - arc basin attenuation and arc - continent collision
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。Beishan orogenic belt passed complex geological evolution by multistage plate divergence - subduction - collision - fitting, with the characteristics of ploycycle multiple orogeny
摘要北山造山帶經歷多期次、多階段的板塊裂解俯沖碰撞拼合的復雜地質演化歷程,具多旋迴復合造山的特色。Combining the isotope geochronological results with the fieldwork observations, we could draw some conclusions as follows : the kunlun - bayan har terranes experienced the subduction of oceanic crust and collision somewhat earlier than the bayan har - qiangtang terranes, with only a very short interval in between and even the collisions overlapped partially in time
_ 2 : 227 - 218ma ,巴顏喀拉和羌塘之間洋殼俯沖,以金沙江巖帶iag型巖漿侵位為標志。 _ 3 : 217 - 212ma ,造山後期巖漿侵位。Geologists and geophysicists have carried out substantial work on petrology, geochemistry, chronology and geophysics, et al., which yields important reference material and constrains for explanations of questions, such as the delamination and exhumation mechanism for the lower crust, models of the rapid uplift of himalayan orogen and deep subduction of india - eurasia plate. while only a little has been done to study the eastern syntaxis at present
地質學家和地球物理學家已經對西構造結進行了大量的巖石學、地球化學、年代學和地球物理學等方面的研究,為解釋下地殼的拆沉、折返機制,喜馬拉雅造山帶的快速隆升和印度-歐亞板塊的大陸深俯沖模式等提供了重要的參考信息和約束條件。分享友人
