章鸿钊在中国地质学史上的贡献及其科学史意义     

曹希平 《地质学报》2022,96(5):1503-1509

中国地质学会第一任会长章鸿钊先生早年留学日本攻读地质学期间，萌生了创立中国地质事业和地质调查机构的设想，并将世界发达国家地质科研机构的情况介绍到中国。回国后，章鸿钊先生着手中国地质事业起步的规划和地质调查机构的设计，并在规划实施阶段做出卓越的贡献。按照章鸿钊的思路创建的中国地质调查所是中国现代科学起步阶段的里程碑。章鸿钊先生自幼国学功底深厚，在身体状况限制了野外地质调查的中年和晚年时期，他专注地质与矿产方面的古籍考证和整理，并将考证结果与地质科学知识相结合，撰写了《石雅》、《古矿录》、《三灵解》等一批论著。章鸿钊先生晚年提出了与燕山运动有别的自中生代晚期至始新世后的震旦运动。  相似文献

Challenges in operationalizing the water–energy–food nexus     

J. Liu  H. Yang  C. Cudennec  A.K. Gain  H. Hoff  R. Lawford 《水文科学杂志》2020,65(Z2):1714-1720

ABSTRACT

Concerns about the water–energy–food (WEF) nexus have motivated many discussions regarding new approaches for managing water, energy and food resources. Despite the progress in recent years, there remain many challenges in scientific research on the WEF nexus, while implementation as a management tool is just beginning. The scientific challenges are primarily related to data, information and knowledge gaps in our understanding of the WEF inter-linkages. Our ability to untangle the WEF nexus is also limited by the lack of systematic tools that could address all the trade-offs involved in the nexus. Future research needs to strengthen the pool of information. It is also important to develop integrated software platforms and tools for systematic analysis of the WEF nexus. The experience made in integrated water resources management in the hydrological community, especially in the framework of Panta Rhei, is particularly well suited to take a lead in these advances.  相似文献

Fluid Geoanalysis in the Chinese Continental Scientific Drilling Project   总被引：8，自引：0，他引：8  

Liqiang Luo  Xiuchun Zhan  Qing Sun 《Geostandards and Geoanalytical Research》2004,28(2):325-331

Mass spectrometry and chromatography were used in the on-line and in situ analysis of fluids in the Chinese continental scientific drilling project. The drilling processes and mud have great effects on the identification of fluids. After considering the effects of air components and artefacts on the deep fluids, we have found that in some segments, helium, methane and carbon dioxide are the main gas components that should originate from the deep Earth. The correlations among gas components are discussed and the fluid profiles in the hole are presented.  相似文献   

青藏高原区域地质调查中几个重大科学问题的思考   总被引：63，自引：33，他引：63  

潘桂棠王立全  朱弟成 《地质通报》2004,23(1):12-19

在世纪之交，中国地质调查局部署的青藏高原近百幅1：25万区域地质调查填图，取得了一系列重要新发现、新进展、新成果，神秘的青藏高原地质构造、结构、组成、演化等问题得到了进一步的认识和理解。喜马拉雅奠基于5．5亿年左右的泛非造山事件基底上，历经奥陶纪至泥盆纪台地沉积，并于石炭纪末转化为印度板块北缘的弧后伸展裂陷带；雅鲁藏布江蛇绿混杂岩带曾是特提斯大洋南侧与冈底斯古岛弧带相对应的中生代弧后扩张盆地；冈底斯带曾经历了晚古生代岛弧造山作用；班公湖-怒江带两侧大量地质特征重大差异表明，班公湖-怒江带是冈瓦纳大陆北界，是印度(滇藏)地层区和华南(羌塘-三江)地层区的分界，是新元古代Rodinia超大陆解体后显生宙特提斯大洋俯冲、消减、碰撞，最后消亡的遗迹。  相似文献   

Possibilities of exchanging know-how, scientific partners and information between China Society of Geochemistry and Brazilian Association of Geochemistry-SBGq     

Carlos Bandeira Luiz Antonio Trindade 《中国地球化学学报》2006,25(B08):59-59

The Brazilian Society of Geochemistry--SBGq founded in 1985, is located at Rio de Janeiro, Brazil, having more than 300 affiliates that represent most of the principal Brazilian universities. The main SBGq way of divulgation is an international magazine-Geochimica Brasiliensis and a site： www.sbgq.org.br/. Regular meeting of SBGq is realized in each two years in odd years The last meeting it has been realized together the Geochemistry of Portuguese Language Countries and Geochemistry Symposium of the MERCOSUL countries （Argentina, Brazil, Paraguay and Uruguay）. During the even years are realized specific meeting as Environmental Geochemistry in Tropical Countries. The SBGq is associated with other Brazilian scientific societies as Latin American Association of Organic Geochemistry--ALAGO. During its existence the SBGq has published approximately 3000 papers related to the environment, lithogeochemistry, isotopes, surface geochemistry, organic geochemistry, coastal environmental geochemistry, secondary environments, hydrogeochemistry, exploration geochemistry, magmatic geochemistry, rare earth geochemistry, geochemistry of carbonations, biogeochemistry, mineral geochemistry, geochemistry vs. geochronology and geochemistry of precious metals.  相似文献
