罗布莎矿的发现及铁的硅化物的晶体化学

0 引言 西藏罗布莎铬铁矿矿物学研究首先是由1981年在罗布莎和东巧两个地幔橄榄岩中发现了金刚石而引发的.1996～2004年,在地矿部地调局和加拿大NSERC资助下开展了"西藏超高压矿物群"的课题研究.     

国土的光荣 广西的骄傲

广西这片英雄的土地素来豪杰并起、英才辈出,明代有抗倭巾帽瓦氏夫人,晚清有抗法勇士冯子材;近代有东兰革命武装早期领导人韦拔群,抗日名将李宗仁;和平年代有农民的好榜样韦江歌,人民的好检察官陈革。如今,先辈们曾经洒过热血、滴过汗水的神奇土地上又出现一位壮族楷模、八桂骄子,     

明清的缩影宁静的前童

前童镇位于浙江省宁海西南,始建于南宋绍定六年（公元1233年）。江南的小镇,宁静的美丽中叙说着历史的沧桑。悠久的历史、深厚的文化积淀和独特的地理环境造就了前童古镇独特的气息,因而前童被称之为“浙江省历史文化名镇”、“浙江省旅游城镇”和“中国历史文化名镇”。〈br〉 前童,是一个不凡的江南明清时期的民居原版,是一幅古韵浓重的乡村画,更是一段优美动人的江南丝竹小调。它以民居布局奇特、明清古建筑群保存完好及人才辈出而闻名遐迩。     

河网化的分区及渠道的布置原则的探讨

根据本区的地形、水文,地质及水文地质特点,按河网化的需要,概可划分为以下几区: 工 区 本区范围位于调查区之南部,标高一般在200—800米之间。地形崎岖,割切强烈,冲沟甚为发育,割切深度一般为10一30M,冲沟长度为500—1000米,长者可达3000—5000M。坡角为20—70°。这些沟谷相互啣接,构成间歇河流。因岩性分布不均,风化强度不一,故在河流间常形成一些袋状地形,如管帅,后泥牛等皆是。这些冲沟与河流构成北部各大河     

建筑的未来 智慧的发展

<正>当前,"智慧"成为热门词汇,从智慧城市到智慧建筑、智慧施工,都日渐成为行业关注的热点。智慧建筑应该是什么样的建筑?我们认为,智慧的建筑应该是以人为本的建筑。智慧建筑"以人为本"建筑是能耗和碳排放的大户。根据《"十二五"绿色建筑科技发展专项规划》,在全社会的能耗和碳排放中,建筑业占比超过40%,远超工业的28%和交通运输的32%。目前,中国建筑95%以上是高能耗建     

身边的典型 学习的楷模

我对李荣江同志的先进事迹,最初是从新闻媒体上获悉的,即《中国国土资源报》刊出的《走进百姓心中的国土人——记浙江省台州市国土资源局派出农村工作指导员李荣江》,与此同时,又在网上浏览了许多有关学习宣传李荣江先事迹的专题报导,而后又视频收看了省国土厅在杭举行的李荣江先进事迹电视电话报告会实况。学习李荣江事迹,我心情倍加激动,他在平凡的岗位做出了不平凡的业绩,为国土系统争得了荣誉,是国土人学习的楷模。     

钓鱼岛的归属及日本右派的野心

约距今2200万年的新近纪中新世早期，菲律宾洋板块斜向俯冲插入欧亚陆板块之下，在板块碰接带的两侧进行不同的地质演化。海沟、火山岛弧、弧后盆地是板块构造理论中洋板块与陆板块碰接时在碰接带附近产生的构造地貌，即“沟、弧、盆系”。菲律宾洋板块俯冲于欧亚陆板块之下到更新世后期（距今约20万年），其构造地貌由洋到陆为大洋-硫球海沟-台湾火山岛弧-弧后盆（边缘海）-中国大陆，其中海沟以东至大陆为东海大陆架。     

不同来源的CO_2的成矿作用及发生作用的方式

CO_2可以来源于地幔,也可以来源于围岩与热液的反应,也可以来源于有机物质的分解等等,但是不管什么来源的CO_2,都对很多金属矿床,尤其是对金矿床和铀矿床的形成起着重要的作用。在成矿作用过程中,CO_2可以作为流体以气相或液相携带金属元素;也可以起着pH缓冲剂的作用,改变溶液的pH值,使成矿元素溶解或沉淀;也可以起着矿化剂的作用,和成矿元素络合,形成络合物并运移到地球化学障处沉淀成矿;也可以起着活化剂的作用,使成矿物质活化便于和硫等矿化剂淋滤成矿物质并富集成矿。     

我的理想我的梦

做高科技的主力 新能源的先锋

在国家住房和城乡建设主管部门的领导下．尤其是在市场管理主管司有关领导的亲切关怀下,我院通过历届领导班子的努力．尤其是通过改制以后的快速成长,获得了工程设计综合甲级证书,揭开了十一院发展历史崭新的一页。我院与兄弟大院相比仍有差距．要继续按照国家住房和城乡建设主管部门的要求,努力将我院发展成为一个国际工程公司型的大院。     

Définition d'une limite multicritère ; stratigraphie du passage Campanien–Maastrichtien du site géologique de Tercis (Landes,SW France)Definition of a multi-criteria boundary; stratigraphy of the Campanian–Maastrichtian interval of the geological site at Tercis (Landes,SW France)

Lithostratigraphy, physicochemical stratigraphy, biostratigraphy, and geochronology of the 77–70 Ma old series bracketing the Campanian–Maastrichtian boundary have been investigated by 70 experts. For the first time, direct relationships between macro- and microfossils have been established, as well as direct and indirect relationships between chemo-physical and biostratigraphical tools. A combination of criteria for selecting the boundary level, duration estimates, uncertainties on durations and on the location of biohorizons have been considered; new chronostratigraphic units are proposed. The geological site at Tercis is accepted by the Commission on Stratigraphy as the international reference for the stratigraphy of the studied interval. To cite this article: G.S. Odin, C. R.

Quaternary stresses revealed by calcite twinning inversion: insights from observations in the Savonnières underground quarry (eastern France)

Calcite samples were extracted both from the rock matrix and the superficial coating of a karstified fault plane of an underground quarry, located in the eastern border of the Paris basin. The karstification is dated as Quaternary. Analysis of mechanical calcite twinning reveals that only the calcite matrix has also undergone a compression trending WNW that can be attributed to the Mio-Pliocene alpine collision. Both coating and matrix have undergone a strike-slip regime with σ₁ roughly trending north–south, that could correspond to the regional present-day state of stress, a strike-slip compression rather trending NNW, modified by local phenomena.
