能源在未来的经济发展中扮演者重要角色。随着我国的经济发展,能源问题已经上升为战略问题。我国在石油能源方面并不富裕,要确保石油安全,就必须走石油进口多元化道路。俄罗斯是一个石油、天然气资源极为丰富的世界能源强国。2008年的世界金融危机为我们提供了一次与俄罗斯远东地区以及西伯利亚地区在能源合作方面的良机。双方携手开辟出一条振兴与开发之路。 相似文献

在俄罗斯远东地区晚中生代花岗岩类年龄和相关地球化学数据的基础上,初步建立了该区晚中生代花岗岩类的年代学格架:大致以145Ma为界,分为侏罗纪(178~151Ma)和早白垩世(142~122Ma)2期。侏罗纪的花岗岩类主要为花岗岩-花岗闪长岩-石英二长岩组合,总体上为准铝质—强过铝质高钾钙碱性系列;早白垩世的花岗岩类主要为花岗岩-石英闪长岩-石英二长岩组合,主要为过铝质钙碱性—高钾钙碱性系列—钾玄岩系列。2期花岗岩稀土元素配分曲线均呈右倾型,重稀土元素曲线较平坦,都富集大离子亲石元素(如U、K)和轻稀土元素。与中国东北地区晚中生代花岗岩类对比,中国东北地区总体以兴安岭为中心,中间为早白垩世的花岗岩类,两侧为侏罗纪花岗岩类对称分布。境内外的侏罗纪花岗岩类构造背景不同,其分布与鄂霍次克洋和太平洋板块的俯冲有关,早白垩世花岗岩类可能形成于鄂霍次克带挤压造山后的伸展垮塌和太平洋板块的俯冲弧后伸展阶段。 相似文献

近年来,俄罗斯远东地区铂族金属矿床勘查取得了长足进展,发现铂族金属矿化与金矿化密切相关,铂族金属矿床与中心型环带状基性-超基性侵入杂岩体在空间和成因上有密切联系,在黑色岩系及褐煤矿床中也发现了铂族金属矿化.上述成果指明了该区铂族金属矿床的找矿方向,发现并探明了一批铂族金属矿床.这些勘查进展对我国的铂族金属矿床勘查具有借鉴意义. 相似文献

<正>中国和俄罗斯已经通过确认双方经由俄罗斯远东地区进行天然气供应的计划,并确定通过更靠近西部的阿勒泰地区输送天然气的新合约,而此次双方的谈判也加强了两国在能源领域的合作关系。西线不亚于东线据不完全统计,自去年3月以来,中俄两国原油、天然气供应签署的协议总金额已高达近7,000亿美元。其中,2013年,双方签署了俄方通过东、西两线对 相似文献

Generalized geothermal data was used to produce two electronic atlases for Asian Russia,Geothermal Atlas of Siberia(GAS)(1995-2000) and Geothermal Atlas for Siberia and Russian Far East(GASRFE)(2009-2012).The atlases include heat flow maps,temperatures at depths of 0.5,1,2,3,5 km and lower boundary of permafrost.Quantitative values of parameters are presented as isolines(GAS) and symbols(GASRFE).GAS website is located at the Trofimuk Institute(www.ipgg.sbras.ru/ru/institute/structure/geophysics/natural-fields).GASRFE provides the most complete geothermal data on Asian Russia,which has been growing for the last 50 years,and is published on the Internet at http://maps.nrcgit.ru/geoterm.In this atlas,data about the depth of permafrost lower boundary( "zero" isotherm) are presented for the first time. 相似文献

The paper describes the sedimentary features and biostratigraphy of the transitional Jurassic to Cretaceous deposits in the continental basins of Priamurie formed after the collision between the Siberian and North China blocks. In Upper Priamurie, the collision occurred in the late Early Jurassic as dated by the emplacement of the post-collisional granites (191Ma) . While in Lower Priamurie and West Priokhotie it could take place in the late Middle Jurassic on the basis of fossil evidence from an accretionary turbidite complex. This event reflected the environmental change from coastal-marine to alluvial plains, often boggy, where coals accumulated. The environmental change is in harmony with that of biota. Systematic study of floral and spores/pollen assemblages, particularly in the sections of interbedded marine and non-marine deposits, makes clear the chronostratigraphic succession of floral associations and shows the possibility of their application for subdivision and correlation of the continental deposits of Priamurie. The coastal-marine environment of the residual post-collisional sublatitudinal basins in the western part of Priamurie (Upper Amur and Dep basins) was replaced by the continental in the late Middle Jurassic and in the eastern part in the Berriasian-Valanginian ( Torom Basin) . Similar environmental change commenced in the submeridional rift basins: the Bureya Basin in the Callovian and the Partizansk Basin in the Hauterivian. Changes in ecosystems occurred frequently during theMiddle Jurassic-Neocomian, but the most substantial changes took place in the late Middle Jurassic and in the end of Late Jurassic. 相似文献
