1913年成立的中央地质调查所(成立时称农商部地质调查所)是中国建立的第一个国家级科研机构,代表了中国现代科学的起始,在中国现代科学发展史上具有举足轻重的地位。在它成立后的几十年间,中央地质调查所在区域地质调查、矿产资源勘查、大地构造学、地震学、土壤学、古生物与古人类学等众多领域,取得了一系列举世瞩目的学术成就,是民国时期我国最享有国际声誉的研究单位。1951年,中央地质调查所被正式改组为中国科学院地质研究所。根据当时新中国地质工作"一元化"的要求,原中央研究院地质研究所和原国民政府资源委员会矿产测勘处的部分地质研究人员也一同并入该研究所,使其成为当时我国最大的地质研究机构。1952年6月开始,刚成立不久的中国科学院地质研究所的科技人员开始分流。首先是研究所的古生物研究人员分流到新成立的中国科学院古生物研究所(即现在的中国科学院南京地质古生物研究所),它是在原中央研究院地质研究所基础上成立的。1952年9月,研究所土壤研究室扩充建设为中国科学院土壤研究所。1952年底左右,因新中国大规模经济建设的需求,大批科技人员分流到刚成立的地质部及所属的地质勘探队。从这一脉络可以看出,中国科学院地质研究所是中央地质调查所的传承和延续,而学术界大多认为中央地质调查所已于解放初期解体或撤销的观点与史实并不相符。 相似文献

A list of all Upper Cretaceous sea-lilies known from the U.S.S.R. is given. Their stratigraphic and geographic distributions are discussed. Three paleogeographic subprovinces, the south-eastern, the northern and the south-western, can be distinguished in the Mediterranean paleobiogeographic province of the U.S.S.R. based on the development and distribution of the Upper Cretaceous crinoids. 相似文献

Eighteen resolutions were adopted by the 12th Session of the Committee on Absolute Dating of Geologic Formations of the U.S.S.R. Academy of Sciences. The resolutions report on the activities of the Committee on age dating and efforts being made to standardize methods and procedures of age dating. Of particular interest are 1) the resolution recommending a proposal to the International Geological Congress and International Geological Union for international unification of the calculation constants required in the potassium-argon method and 2) a recommendation concerning a more detailed breakdown of the Precambrian. — F.

The recent experience of the rising cost of exploiting new material resources in the U.S.S.R. has led to exploration of alternative methods, particularly greater intensification of exploitation. The regional variations in the balance between intensive and extensive methods is considerable and is consequently an important aspect of Soviet geographical research. This paper discusses the criteria and methodology for this crucial economic/resource regionalization of the U.S.S.R. 相似文献

Recent seismological studies of low-velocity layers in the U.S.S.R. have led to the development of new methods of investigation. The most important results obtained are presented in this paper. Several new techniques of record treatment and advanced computer programs make it possible to solve two-dimensional problems of seismic wave propagation in complex media and to outline zones of velocity inversion in the crust and mantle of many regions in the U.S.S.R.Zones of this type seem to occur only locally and are typical of some particular geostructures. Lateral inhomogeneities are also found to be closely related to geological features. Their depths sometimes can reach 300–400 km. 相似文献

A very interesting and informative paper on widespread occurrence of a thermal hydrosphere. Geothermal power uses are discussed. Distribution of heated waters, some up to 150° C is discussed in considerable detail, especially with reference to possible power utilization of the geothermal energy. Seven hydrothermal regions of the U.S.S.R. are discussed and delineated. Chemical quality of waters is referred to. There is a summary listing of locations in the U.S.S.R. where thermal waters could be utilized for generation of electric power. — B. N. Cooper. 相似文献

A major field of research since the 1920s has been methods and theories of economic regionalization. The territorial-production complex is now recognized as a key developmental tool within the framework of economic-planning regions. Recently, there has been a more marked growth of study into problems of natural-resource development, social progress and change in the U.S.S.R. as well as into the spatial structure of other nations, particularly other socialist countries and non-socialist developing countries. 相似文献

The compilation of statistical data for 269 seismic crustal sections (total length: 81,000 km) which are available in the U.S.S.R. has shown that the preliminary conclusions drawn on relations between the elevation of the surface relief and Bouguer anomalies on one hand and crustal thickness (depth to the M-discontinuity) on the other hand are not fulfilled for the continental part of the U.S.S.R. The level of isostatic compensation has been found to be much deeper than the base of the earth's crust due to density inhomogeneities of the crust and upper mantle down to a depth of 150 km.
The results of seismic investigations have revealed a great diversity of relations between shallow geological and deep crustal structures:
Changes in the relief of the M-discontinuity have been found within the ancient platforms which are conformable with the Precambrian structures and which can exceed 20 km. In the North Caspian syneclise, extended areas devoid of the “granitic” layer have been discovered for the first time in continents. The crust was found to be thicker in the syneclises and anteclises of the Turanian EpiHercynian plate. In the West Siberian platforms these relations are reversed to a great extent.
Substantial differences in crustal structure and thickness were found in the crust of the Palaeo zoides and Mesozoides. Regions of substantial neotectonic activity in the Tien-Shan Palaeozoides do not greatly differ in crustal thickness if compared to the Kazakhstan Palaeozoides which were little active in Cenozoic time. The same is true for the South Siberian Palaeozoides.
The Alpides of the southern areas in the U.S.S.R. display a sharply differing surface relief and a strongly varying crustal structure. Mountains with roots (Greater Caucasus, Crimea) and without roots (Kopet-Dagh, Lesser Caucasus) were found there.
The Cenozoides of the Far East are characterized by a rugged topography of the M-discontinuity, a thinner crust and a less-pronounced “granitic” layer. A relatively small thickness of the crust was discovered in the Baikal rift zone.
The effective thickness of the magnetized domains of the crust as well as other calculations show that the temperature at the depth of the M-discontinuity (i.e., at depths of 40–50 km) is not higher than 300–400° C for most parts of the U.S.S.R. 相似文献

论旅游地学与地质公园的创立及发展,兼论中国地质遗迹资源——为庆祝中国地质科学院建院60周年而作 总被引：1，自引：0，他引：1
笔者从中国地质科学院建立之始,就随着地质部陈列馆(即现中国地质博物馆)划归中国地质科学院领导,而成为其创始研究人员,60年来从没离开过,因此见证了其全部历史。在中国地质科学院工作过程中,以笔者为主,利用中国地质科学院的学科优势和挂靠单位中国地质学会学术团体这个全国性学术交流平台的有利条件,将地球科学运用到为中国旅游业发展服务中去,从而创立了一门地学与旅游相结合的新学科——旅游地学(Tourism Earth-science);在旅游地学理论指导下,提出了建立地质公园的建议和一整套实施方案,经过艰辛努力,终于促使地质公园得以建立;地质遗迹是建立地质公园和发展旅游业的重要地质资源,是旅游地学的主要研究对象。旅游地学与地质公园都是中国地质工作者的首创,是中国地质科学院的重大科学研究成果之一,其在中国地质工作发展史上具有里程碑意义。本文将旅游地学和地质公园产生的历史背景、研究内容、发展过程、建设现状与国内外发展趋势,以及地质遗迹资源的类型划分、评价准则、形成与分布规律、应用保护现状综述如下,以作为献给中国地质科学院建院60周年的礼物。 相似文献

辽东半岛一直是研究华北克拉通减薄的热点地区,前人对于晚三叠世时期辽东半岛的构造环境一直有不同的认识。本文选择辽东岫岩地区出露的后边沟岭黑云母二长花岗岩和大黑坑石英二长闪长岩进行了LA-ICP-MS锆石U-Pb年代学、岩石地球化学的研究,并对上述两个岩体的岩浆来源及形成环境进行了讨论,得出以下认识:辽东岫岩地区后边沟岭黑云母二长花岗岩和大黑坑石英二长闪长岩均形成于晚三叠世(220.9±1.2 Ma和220.3±1 Ma);地球化学研究表明:后边沟岭黑云母二长花岗岩具高硅、富碱的特征,属A型花岗岩;大黑坑石英二长闪长岩具高镁的特征;后边沟岭黑云母二长花岗岩和大黑坑石英二长闪长岩具有相似的稀土元素和微量元素特征,二者均显示轻稀土分馏明显,重稀土分馏不明显的特征,均富集大离子亲石元素Rb、K,亏损Ba、Sr,富集高场强元素Th、La、Ce、Nd、Hf、Tb,而亏损P、Nb、Ta、Y等元素;二者具有相同的岩浆来源且均具有壳幔混源的特征;在220.9±1.2～220.3±1.0 Ma这一时期,辽东岫岩地区整体可能处于地壳伸展减薄的构造背景,后边沟岭黑云母二长花岗岩和大黑坑石英二长闪长岩均形成于这一构造背景中,上述两个岩体的形成可能与大陆深俯冲和扬子—华北之间发生陆陆碰撞造山作用后所引起的华北克拉通减薄有关。 相似文献
