tethys ocean 中文意思是什麼
tethys ocean
解釋
古地中海-
Thus, it can be clearly recognized that the global continents located at near equator and southern hemisphere, showed the characteristics of range along latitude ; chinese continental blocks still located among the laurentia, siberia and gondwana in paleozoic ; following the fast moving of siberia plate to northwards, the amalgamation in north - south direction at the western parts of laurentia and gondwana, subducted the lapetus and rheic oceans, until to form the uniform pangea in the late stage of paleozoic ; however australia and india plates in eastern gondwana move and disperse gradually to southwards, to extend crust and form the paleo - tethys ocean ; the chinese continental blocks and adjacent blocks still located in paleo - tethys ocean, preserved the status of dispersion, gradually moving to northwards, showed the characteristics of range along north - south orientation, until carboniferous and triassic a series of local collisions happened in tianshan - hing ' anling, kunlun, qinling - dabie, jingshajiang and shaoxing - shiwandashan zones, thus the most part of chinese continental blocks amalgamated to eurasia continent
由此可以清晰地看出，在古生代早期全球各大陸的主要部分都位於赤道附近及南半球，大致表現為沿緯度、呈東西向排列的特徵，中國及鄰區的小陸塊群在古生代始終都處在勞倫大陸、西伯利亞與岡瓦納大陸之間；隨著西伯利亞大陸的快速北移，在勞倫大陸與岡瓦納大陸的西部地區發生南北向拼合，亞皮特斯洋和里克洋的消亡，到古生代晚期形成統一的泛大陸；而岡瓦納大陸的東部（澳大利亞和印度等）則逐漸向南移動、離散，地殼張開，構成古特提斯洋；中國及鄰區的小陸塊群則一直處在古特提斯洋中，保持離散狀態，總體上緩慢地向北運移，並逐漸轉為近南北向的排列方式，石炭紀到三疊紀才在天山興安嶺、昆侖山、秦嶺大別、金沙江和紹興十萬大山等地段發生一系列局部性的陸陸碰撞，使中國大陸地塊的大部分逐漸併入歐亞大陸。 -
The marginal ocean basin ' s formation and evolution model may be as follows : early triassic, rift was formed by extension and splitting in india ( gondwana ) continental margin during it was drifting southward ; late triassic, the rift had been joined in the neo - tethys ocean in the east and converted into initial ocean basin, and ayila - zhongba micro - continental was formed in north of the rift
洋盆的演化模式是：早三疊世，隨著印度（岡瓦納）大陸向南漂移，其北部邊緣因引張裂解產生裂谷，于晚三疊世向東開口與新特提斯洋主體連通，洋盆初具洋殼性質，北側形成阿依拉仲巴微陸塊。 -
The authors put forward that daba - xiugugabu ophiolite belt originated from an ancient oceanic crust fragment of india continental northern marginal ocean basin, that was approximately synchronous with the formation and evolution period of the neo - tethys ocean
筆者提出該區蛇綠巖來源於印度大陸北緣洋盆的洋殼碎片，這個陸緣洋盆與新特提斯洋主體的形成和演化準同步。 -
During subduction northward of neo - tethys oceanic plate, ayla - zhongba micro - continental, the marginal ocean basin and india continental drifted northward all together, the marginal ocean basin was gradually contracted and closed by compressed of india continental
在新特提斯洋板塊向北俯沖消減過程中，阿依拉仲巴微陸塊、陸緣洋盆和印度大陸一起隨著向北漂移，在印度大陸向北擠壓作用下洋盆逐漸收縮以致最終閉合。 -
Thus, they might be derived from a back - arc basin with an archipelagic system in paleo - tethys, instead of a large ocean basin. the isotopic geochemistry shows that the jinshajiang ophiolitic melange has higher e nd ( t ) values ( + 7. 42 - + 5. 44 ), suggesting that it may be derived from a lree depleted mantle source without significant contamination by the continental crust, but affected slightly by a fluid from a subducted ocean crust
同位素地球化學研究表明，金沙江蛇綠混雜巖具有較高的_ （ nd ） （ t ）值（ + 7 . 42 + 5 . 44 ）暗示蛇綠巖來源於lree長期較虧損的地幔源，演化過程中沒有受到陸源物質的明顯混染，而主要受到少量俯沖洋殼析出流體的影響。 -
Kashan block of iran is the first oversea risk exploration block of chinese petrochemical co. ltd. kashan block is located in the south - west edge of iranian basin. on the structure, it belongs to alpines - himalayan orogeny belt controlled by dynamic system of tethys - indian ocean
伊朗卡山探區是中石化海外的第一塊風險勘探區塊，位於中伊朗盆地西南邊緣，構造上屬于特提斯?印度洋動力體系作用控制的喜馬拉雅-阿爾卑斯造山帶。
