從大陸張裂到海底擴張The sea floor is spreading away from the mid-ocean ridges.
海底正在從大洋中脊擴張開來。Through the systematic analysis and contrast studies on topographical environment characteristics of these typical regions, it is found that the hydrothermal activity only occurs under the circumstance of the particular topographical environment, though it distributes widely in the tensional tectonic environment, for instance, the mid - ocean ridges, transform faults zones, back - arc spreading basins and the modern marine craters regions
通過對典型熱液區地形環境特徵的系統分析和對比研究發現盡管現代海底熱液活動廣泛分佈在大洋中脊、轉換斷層、弧后擴張盆地等各種不同的張性構造環境及現代海底火山活動區,但也僅出現在特殊的地形環境條件下。It seems that submarine magmatism and hydrothermal activity provided abundant ore - forming material for partly strata of mogaganri and yanshiping formations during the extension of bangongcuo - nujian marginal sea in early - middle jurassic. therefore parts of jurassic mogaganri and yanshiping formations became original source of ore - forming material. in later early jurassic, the collision and collage between qiangtang block and nianqing - tanggula block made favorable conditions in geological structure, magma and ore - forming fluids for the formation of gold deposits
在早-中侏羅世班公錯?怒江邊緣海擴張過程中,海底巖漿及其熱液作用,為侏羅系木嘎崗日群和雁石坪群部分層位提供了大量的礦源,使其成為初始礦源層;早白堊世晚期,羌塘地塊和岡底斯?念青唐古拉地塊碰撞拼貼,造成了有利的構造條件、巖漿條件、成礦流體條件,形成礦床。The mariana trough is an actively opening back arc basin that lies at the eastern edge of the philippine sea plate, and in the transition time from rift to sea floor spreading
位於菲律賓板塊和太平洋板塊之間的馬里亞納海槽,處于弧后張裂向海底擴張的過渡階段,是深入研究板塊運動與弧后擴張動力學過程的理想地區。The abnormalities in the seasons and the weather, the rapid melting of the polar ice cap, the rising temperature of the oceans, the continuous expansion of the hole in the ozone layer, the acid rain given back to us by mother earth, sinking land masses and rising sea levels - what do all these reactions of the natural environment tell us that things turn for the worse when they reach the extreme seems not to be something which people take heed of
人類賴以生存的地球已是岌岌可危,生態環境在不斷的破壞下已產生了顯著的變化,四季氣溫異常北極冰巖急速溶化海水水溫高漲臭氧層的破洞繼續擴張大自然「還贈」給人們的酸雨陸地下陷海平面上升,這種種的自然界反應到底給了我們什麼啟示?物極必反的道理,似乎很難在人們心中起警惕的效應。Now, sr isotopes can be used not only to constrain the origin and evolution of magma and hydrothermal ore - forming solutions, calculate the scale and degree of lithogenesis and ascertain the relations between fluids and rocks, but also to study sea - level fluctuation, plate movement, ocean - floor spreading and lithogenic evolution
現在,鍶同位素不僅在示蹤巖漿及成礦熱液的來源和演化、計算晚期成巖改造作用的規模和程度及流體/巖石比等方面已趨于成熟,並且越來越廣泛運用於海平面變化、板塊活動、海底擴張、成巖演化等方面的研究。The rifts therefore represent divergent plate boundaries where seafloor spreading is taking place
這樣,大洋中脊就成為板塊分離邊界,海底擴張就發生在這里。China netcom already owned some undersea cable networks in asia pacific by the time it listed china netcom communications group ( hong kong ) in november 2004, and stated in the prospectus that it planned to expand its overseas services to win long - distance and value - added customers in china
