    俄罗斯将成功说服联合国罗蒙诺索夫山脊其要求根据北冰洋,大大使周一表示赞成排除。
    " I am sure, that the process [of defining the external boundaries of the Russian continental shelf] will be crowned with success," Anton Vasilyev, who is also a senior official in the Arctic Council, said at a press conference dedicated to the forum "The Arctic: Territory of Dialogue. "

    Russia and Canada's foreign ministers, Sergei Lavrov and Lawrence Canon, agreed on Thursday that scientific evidence should resolve the dispute .
    俄罗斯和加拿大的外长拉夫罗夫和劳伦斯佳能周四表示,同意科学证据应该解决争议 。
    The process of defining whether the ridge is a continuation of the Russian continental shelf or not is unlikely to lead to conflicts between Russia and other countries, Vasilyev added.
    瓦西里耶夫说,定义是否山脊是俄罗斯大陆架的延续与否的过程是不太可能导致俄罗斯和其他国家之间的冲突。
    Russia first laid claim to the territory in 2001, but the United Nations demanded more conclusive evidence.
    俄罗斯第一奠定声称在2001年的领土,但联合国要求更确凿的证据。

                新的航空物探研究欧亚大陆盆地和罗蒙诺索夫山脊:流域开发的启示
                在1998年和1999年,新的航空物探调查北冰洋的欧亚盆地生产的第一置的重力和磁力测量,盆地西半部。
                These data increase the density and extend the coverage of the US Navy aeromagnetic data from the 1970s.
                这些数据的密度增加,从20世纪70年代,美国海军的航空磁测数据的覆盖面扩大。
                The new data reveal prominent bends in the isochrons that provide solid geometrical constraints for plate reconstructions.
                新的数据显示突出的弯曲等时线板重组提供了坚实的几何约束。
                Tentative identification of anomaly 25 in the Eurasia Basin links early basin opening to spreading in the Labrador Sea before the locus of spreading in the North Atlantic shifted to the Norwegian-Greenland Sea.
                暂定识别异常25欧亚大陆盆地链接早期盆地开幕前拉布拉多海蔓延的轨迹分布在北大西洋转移到挪威,格陵兰海。
                With the opening of the Labrador Sea, Greenland began ∼200 km of northward movement relative to North America and eventually collided with Svalbard, Ellesmere Island, and the nascent Eurasia ocean basin.
                随着对外开放的拉布拉多海,格陵兰开始北移相对于北美和最终相撞,斯瓦尔巴群岛,埃尔斯米尔岛和新生的欧亚海盆〜200公里。
                Both gravity and magnetic data sets reconstructed to times prior to chron 13 show a prominent linear anomaly oriented orthogonal to the spreading center and immediately north of the Yermak Plateau and Morris Jesup Rise.
                重力和磁力数据集重建之前,历代志上13倍显示出突出的线性异常面向垂直传播中心,并立即北部的的叶尔马克高原的和莫里斯杰塞普上升。
                This anomaly may mark the locus of shortening and possibly subduction as Greenland collided with the nascent Eurasia Basin and impinged upon the southern Gakkel Ridge.
                这种异常可能标志着格陵兰相撞新生的欧亚流域和南部加科尔山脊紧挨着缩短,并可能俯冲的轨迹。
                This collision may have contributed to volcanism on the Morris Jesup Rise.
                这种碰撞可能导致火山莫里斯杰塞普上升。
                By chron 13, Greenland had ended its northward motion and had become fixed to North America, and the plateau north of Greenland had rifted apart to become the Morris Jesup Rise and the Yermak Plateau.
                chron的13,格陵兰岛已经结束了其向北运动,已成为固定北美,格陵兰高原北部割开除了成为莫里斯的杰塞普上升和叶尔马克高原,。

                  北极海洋地质考察(MAGE)摩尔曼斯克,俄罗斯在1990年收购的多道地震反射数据提供北极地区的地质结构在77-80°,东经115-133°E,其中欧亚盆地的第一个视图北冰洋毗邻变换被动大陆边缘的拉普捷夫海。
                  South of 80°N, the oceanic basement of the Eurasia Basin and continental basement of the Laptev Sea outer margin are covered by 1.5 to 8 km of sediments.
                  80°N以南,海洋地下室欧亚盆地和大陆基底的拉普捷夫海外缘的1.5到8公里的沉积物覆盖。
                  Two structural sequences are distinguished in the sedimentary cover within the Laptev Sea outer margin and at the continent/ocean crust transition: the lower rift sequence, including mostly Upper Cretaceous to Lower Paleocene deposits, and the upper post-rift sequence, consisting of Cenozoic sediments.
                  两种结构的序列来区分内沉积盖层拉普捷夫海外缘,并在大陆/海洋地壳的过渡:较低的裂谷层序,包括多为上白垩统下古存款,上裂谷后序列,由新生代沉积物。
                  In the adjoining Eurasia Basin of the Arctic Ocean, the Cenozoic post-rift sequence consists of a few sedimentary successions deposited by several submarine fans.在北冰洋毗邻欧亚盆地,新生代裂谷后的序列由几个海底扇沉积了几沉积序列。
                  Based on the multichannel seismic reflection data, the structural pattern was determined and an isopach map of the sedimentary cover and tectonic zoning map were constructed.
                  基于多道地震反射数据,结构模式,确定和构造沉积盖层等厚图和构造区划图。
                  A location of the continent/ocean crust transition is tentatively defined.
                  大陆/海洋地壳过渡的位置暂时定义。
                  A buried continuation of the mid-ocean Gakkel Ridge is also detected.
                  埋延续的大洋中加科尔的岭也检测。
                  This study suggests that south of 78.5°N there was the cessation in the tectonic activity of the Gakkel Ridge Rift from 33–30 until 3–1 Ma and there was no sea-floor spreading in the southernmost part of the Eurasia Basin during the last 30–33 my South of 78.5°N all oceanic crust of the Eurasia Basin near the continental margin of the Laptev Sea was formed from 56 to 33–30 Ma.
                  这项研究表明,南部78.5°N“是从33-30的加科尔岭裂谷构造活动停止,直到3-1马有没有海底扩张在欧亚大陆盆地最南端的一部分,在过去30-33我的南78.5°N欧亚大陆盆地靠近大陆边缘的拉普捷夫海所有的大洋地壳形成56至33-30马。

                        美亚和加拿大盆地的地质构造发育,北冰洋
                        美亚盆地是逆时针旋转开一个极点净重加拿大麦肯齐河谷的两个阶段的产物。
                        Phase 1 opening brought ocean–continent transition crust (serpentinized peridotite?) to near the seafloor of the proto-Amerasia Basin, created detachment on the Eskimo Lakes Fault Zone of the Canadian Arctic margin and thinned the continental crust between the fault zone and the proto-Amerasia Basin to the west, beginning about 195 Ma and ending prior to perhaps about 160 Ma.
                        第1阶段开放带来了海陆过渡地壳(蛇纹石化橄榄岩)附近的海底创建支队爱斯基摩湖断裂带加拿大北极边缘变薄之间的大陆地壳的断裂带和原原美亚盆地,美亚盆地西部,约195 Ma开始和结束前或许大概160马。
                        The symmetry of the proto-Amerasia Basin was disrupted by clockwise rotation of the Chukchi Microcontinent into the basin from an original position along the Eurasia margin about a pole near 72°N, 165 W about 145.5–140 Ma.
                        原美亚盆地的对称性被破坏由楚科奇微顺时针旋转倒入盆内,约145.5-140麻沿欧亚大陆边缘约72°N附近的一极,165 W从原来的位置。
                        Phase 2 opening enlarged the proto-Amerasia Basin by intrusion of mid-ocean ridge basalt along its axis between about 131 and 127.5 Ma.
                        第2阶段扩大开放原美亚盆地洋中脊玄武岩沿其轴线约131和127.5马之间的入侵。
                        Following intrusion of the Phase 2 crust an oceanic volcanic plateau, the Alpha–Mendeleev Ridge LIP (large igneous province), was extruded over the northern Amerasia Basin from about 127 to 89–75 Ma.
                        第2阶段的地壳海洋火山高原的入侵之后,阿尔法门捷列夫海岭LIP(大火成岩省),被挤压在美亚盆地北部约127至89-75马。
                        Emplacement of the LIP halved the area of the Amerasia Basin, and the area lying south of the LIP became the Canada Basin.
                        安置唇美亚盆地面积减半,并成为加拿大海盆区地势南唇。
