摘 要：首次在内蒙克什克腾旗境内的大兴安岭山脉的北大山上，发现世界罕见的花岗岩石林地貌景观。花岗岩石林是在特殊的内、外动力作用下形成的。

The mires in northern Great Khing'an mountains are particular with high latitudes and high altitudes.

大兴安岭北部地区由于在高纬、高海拔双重因素作用下，形成了独特的山地沼泽类型。

As a result of Pacific plate subducting toward Eurasian plate, a long acidic volcanics belt formed which extends from northeast to south of China and covers nearly 1 million km〓. This belt is also an important area of precious and nonferrous metal deposits in China.

受太平洋板块向欧亚板块俯冲作用的影响，我国从东北的大兴安岭经过山东、江西、福建、广东一直到广西境内，形成了一条中新生代酸性火山岩带，分布面积近100万km〓，是我国重要的金、银贵金属及铅、锌、铜等有色金属矿床分布区域。

Based on the detailed study of seismic tomography image in South China, and according to the geotectonic environment and shape and heat of asthenosphere upwelling, we divided the structure of lithosphereasthenosphere at the Mesozoic upper mantle of Eastern China into three types.(1)Continental platform area (North China platform and Yangtze platform): asthenosphere upwelled along paleorift; over the plume head, the granitic rocks of crust and mantle mixed and correspondingly, Au, Cu, Mo, PbZn, etc. mineralizationconcentrated regions were formed; and at the steep contact belt of asthenosphere and the thick area of lithosphere, mediatebasic complex was formed.(2)Central area of fold zone: asthenosphere was "recumbent" at suitable depth, with adequate heat and in a great extent; by heat conduction, the interior of partial crust remelted, and the crustsource granitic rocks, and correspondingly, W, Sn and rare elements mineralizationconcentrated regions were formed.

在深入研究华南地震层析成像的基础上，按照大地构造环境和软流圈上涌形状和热度，将中国东部中生代上地幔中岩石圈软流圈构造划分为3类：(1)陆台区，软流圈沿古裂陷上涌，其柱头上方形成幔壳混熔花岗质岩及相应Au、Cu、Mo、PbZn等矿集区，并于软流圈与岩石圈厚区之陡接触带形成中基性杂岩及相应Fe矿集区；(2)褶皱带中心区，软流圈在适当深度、热量充足、较大范围内&平卧&，因热传导而致使地壳内物质部分重熔，形成壳源型花岗质岩及相应的W、Sn、稀有元素矿集区；(3)褶皱带边缘区(大兴安岭南部及华南南缘)，在软流圈上涌柱上方形成幔源或幔壳混熔的花岗质岩，相应为Cu、Au、PbZn、Mo、Ag矿集区。

Such features are typical of ancient lower continental crust, e.g., Archean granulite terranes that experienced extensive U-Th loss and developed time-integrated low radiogenic Pb compositions. The occurrence of the west Ujimqin andesites indicates the existence of ancient continental lower crust beneath the NE China fold belt.4 The Mesozoic granitoids in the Zhangguangcai Range and Jiamusi block have lower Nd ε_(Nd =-3.5～+ 2.1, T_ = 1.0～1.27Ga and highly radiogenic Pb and Sr isotopic composition ~(206Pb/~(204)Pb = 18.4～18.9,~(87)Sr/~(86)Sr = 0.705～0.711, suggesting that the pelagic sediments of the Paleo-Asian Ocean or their metamorphosed derivates were an important component in the region.5 The Pb isotope mapping results show that the mafic rocks in the northern Hinggan Mountains have higher and weakly variable ~(206)Pb/~(204)Pb ratios than those from the southern Hinggan Mountains and the Liaoyuan-Yanji area.

该套岩石的出现为证明东北地区存在古老大陆下地壳提供了重要证据。4张广才岭-佳木斯地区中生代花岗岩表现出低ε_(-3.5～+2.1)、高T_(1.0～1.27Ga)和高放射成因Sr~(87Sr/~(86)Sr=0.705～0.711和Pb同位素组成~(206Pb/~(204)Pb=18.4～18.9，反映了古亚洲洋远洋沉积物或变沉积岩为区域地壳的重要组分之一。5同位素填图结果表明，大兴安岭北区基性火山岩表现出较高且变化小的~(206)Pb/~(204)Pb比值；而南兴安岭-辽源-延吉地区中生代基性火山岩整体上表现出相对北区低~(206)Pb/~(204)Pb同位素比值特征。

Hu 81 to go abroad soon, finishing out a quill, when the old objects and old photographs, then, he and fat are as educated youth in the mountains of Daxinganling jump the queue, the mountains of life so young and fit of their duck to water.

胡八一出国在即，整理旧物时翮出一张老照片，那时，他和胖子正作为知青在大兴安岭的山区插队，山里的生活让年轻气盛的他们如鱼得水。

The authors think that the magmas of the intermediate-acid volcanic rocks were derived from basaltic magmas of the lower crust and are mixed magmas produced by the increase of geothermal gradients due to diapiric injection of basaltic magmas and partial melting of intermediate-basic metamorphic igneous rocks in the lower crust,and that they resulted from a series of tectonomagmatic activities that took place when the closing of the Mongolian-Okhotsk sea trough and continent-continent collision caused crustal thickening and brought about the formation of the Hinggan-Mongolian orogenic belt in the process of oblique subduction of the Paleo-Pacific plate beneath the Siberian plate.

中文摘要：通过对大兴安岭北段晚侏罗世吉祥峰组中酸性火山岩的岩石地球化学研究，发现其中存在高Sr低Y型火山岩，即文献上所称的埃达克质岩，笔者认为中酸性火山岩的岩浆起源于下地壳玄武质岩浆，为玄武质岩浆底辟上侵引起地热梯度增加、下地壳中基性变质火成岩石部分熔融的之混合岩浆，是古太平洋板块向西伯利亚板块斜向俯冲过程中，蒙古鄂霍次克海槽封闭，陆壳碰撞使地壳加厚，形成兴蒙造山带时所引起的一系列构造岩浆活动。

The paper has introduced general situation of summer forest fire's occurrence since 1965 in Daxinanling area,and analyzed both objective and subjective reasons for its occurrence,such as flammables,weather condition,circulation,exterior settings,and insufficient awareness,not strict enough of wild fire source control and so on.

介绍大兴安岭地区自1965年至今的夏季森林火灾发生概况。分析夏季森林火灾发生的客观原因有：林内可燃物状况、天气状况、环流状况、外部环境情况；主观原因有领导重视不够、对野外火源管理不严。

An experiment was conducted to measure the carbonaceous gas CO2, CO, C(subscript xH released from 22 types of fuels (9 species of arbors, 7 species of bushes and 6 species of herbages) in Daxing'an Mountain during the combustion process sing the method of field investigation combined with indoor combustion environment control. The emission factors of different gases were calculated.

采用外业调查和室内控制环境实验相结合的方法，对黑龙江省大兴安岭地区22种（9种乔木、7种灌木和6种草本）可燃物类型燃烧过程中释放的含碳气体CO2、CO、C(下标 xH进行了测定，并计算了不同气体的排放因子。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
