Global surface temperature shows an increasing trend over the past 100 *** and natural factors have been invoked to explain this warming,but their relative contribution and the spatial variability remain *** on a 2650-year temperature record from a stalagmite near beijing,we explore the possible impacts of human activity on the warm season temperature in beijing since the industrial era using the method of singular spectrum analysis(SSA).The results suggest that the warm season temperature in beijing under the natural forcing should have an overall decreasing trend for the past 13. years(1870 to 2000 AD) with an amplitude of 0.45±0.84℃,while the instrumental record and stalagmite data show an increase of 1.08℃.These imply that human activity would have caused an increase in the warm season temperature of beijing for about 1.53.0.84℃compared to its natural trends,from 1870 AD to 2000 *** results also suggest that anthropogenic forcing began to significantly influence the temperature since 1870 AD,and the effect further intensified since 1915 AD.

锡石是花岗伟晶岩中重要的含锡矿物。喜马拉雅淡色花岗岩带中多个花岗岩-伟晶岩系统均产出锡石。富锂伟晶岩中锡石的显微结构与化学组成及其对岩浆分异演化的指示意义尚不清楚,亟待开展相关研究。本文调查了喜马拉雅东段库曲岩体西侧产出的多条含锂辉石伟晶岩脉,其规模不等,岩相分带简单,主要岩相带为锂辉石-石英-钠长石带或锂辉石-块体长石-石英-(白云母)带,也见钠质细晶岩。选取3.含锂辉石伟晶岩脉中的锡石开展阴极发光(CL)和原位微区分析测试(EPMA和LA-ICP-MS)研究。锡石的元素替代机制以2(Nb,Ta)^(5+)+Fe^(2+)→3.n^(4+)和同价置换(Ti^(4+),Zr^(4+),Hf^(4+),U^(4+))→Sn^(4+)为主,部分锂辉石伟晶岩中的锡石出现Fe对Sn和Nb的置换。锡石呈现4种阴极发光特征(黑色、灰色、振荡环带以及白色):黑色区域具有明显高的Nb、Ta、Fe、Zr、U和Ga含量,相对高的Hf含量,以及较大的Ti含量变化范围;灰色区域和振荡环带区域的化学组成相近,振荡环带具有略高的Nb、Ta和Fe含量,相对低的U含量;白色区域具有相对低的Nb、Ta、Fe、Zr、U和Ga含量,以及略低的Hf含量。锡石阴极发光特征与化学组成密切相关,Zr、U、Ga、Hf含量与锡石阴极发光特征具有一定联系。锡石的阴极发光结构(CL结构)主要为均一结构和不均一结构(核-边正环带、补丁以及核-边反环带),包括黑色晶体、灰色晶体、振荡环带晶体,黑色核+振荡环带/灰色边及补丁、灰色核+振荡环带/灰色边及补丁、振荡环带/黑色区域+白色丝带状边/棉絮状补丁、以及振荡环带/灰色/黑色核+黑色边。锡石CL结构的演化序列自内向外表现为黑色核部/晶体→灰色或振荡环带区域/晶体→(白色/黑色区域),向亏损Nb、Ta、Fe、U、Ga,弱亏损Zr、Hf、Y、Ti元素,以及高Ta/(Nb+Ta)值和低Zr/Hf值的方向演化,晚期可出现Fe的富集。锡石的CL结构和化学组成对比发现:同一伟晶岩脉中的含锂辉石伟晶岩的分异演化程度低于锂辉石伟晶岩,共存矿物的结晶分异可能产生富Nb和富Ta两组锡石,不同含锂辉石伟晶岩脉在岩浆化学特征和演化过程具有明显差异。锡石CL结构与化学组成能够揭示锂辉石伟晶岩的化学特征与形成过程。

以富有机质黑色页岩为代表的页岩油、页岩气资源近年来成为全球范围内油气勘探、开发领域的研究热点。该岩性在中国陆相湖盆中主要为来源复杂的细粒沉积岩,其中发育有一类特殊的纹层状泥晶白云岩。该类白云岩的岩石学、矿物学微观特征和地球化学特征既区别于常见的次生白云石化成因白云岩,又与微生物成因白云岩不同,被定义为一类新型的火山-热液沉积型白云岩。在研读大量国内外文献的基础上,综述了现代湖相白云石全球分布及形成环境特征,并展示了白云岩成因模式研究进展。重点选择了均在拉张构造背景下所形成的三塘湖盆地和准噶尔盆地芦草沟组、酒西盆地下沟组和二连盆地腾格尔组发育的火山-热液沉积型白云岩为研究对象,并进行对比研究。发现该类白云岩的特征:(1)保留有完好的原始微米级纹层结构和微晶晶体,后期受到的成岩作用较弱;(2)与半深—深湖黑色泥页岩互层且缺乏蒸发作用特征,并含有不同比例的火山-热液矿物;(3.锶同位素显示成岩流体具有深源(壳-幔混合)特征;(4)含有丰富的有机物质,并与油气分布展现出较强的耦合关系。最后,提出应加强该类白云岩研究、利用其蕴含的特殊地质信息进行构造背景示踪及探讨其与油气生成关系。

东秦岭伟晶岩区是我国著名稀有金属产地,是秦岭造山带规模最大、稀有金属矿化最丰富的伟晶岩区。官坡地区以伟晶岩脉数量多、含矿伟晶岩脉占比高、稀有金属矿化类型全(锂、铍、铌、钽、铯)、产出具有一定规模的锂矿化伟晶岩和多种稀有金属矿物为特色,是东秦岭伟晶岩区最具代表性和典型性的伟晶岩密集区。官坡地区由北西至南东依次产出火炎沟锡铌钽矿、南阳山、七里沟-前台和蔡家沟锂矿。稀有金属伟晶岩内部结构分带型式多样,呈弱分带(均一结构和分层结构)和复杂分带(主要为对称分带);伟晶岩类型主要是复杂型锂辉石亚型,少量为复杂型锂云母亚型和钠长石-锂辉石型;总体具有高硅、富碱、过铝质特征,富集大离子亲石元素(Rb、K)和高场强元素(Nb、Ta、Hf),亏损Ba和Ti,具有低的Nb/Ta值,稀土元素四分组效应明显,显示伟晶岩岩浆高度分异演化特征。矿物学研究结果表明,与火炎沟含锡伟晶岩相比,南阳山、七里沟和蔡家沟稀有金属伟晶岩(主要是锂矿化伟晶岩)岩浆具有更高的分异演化程度。官坡地区存在晚奥陶世-早志留世伟晶岩岩浆活动,稀有金属伟晶岩主要成岩成矿峰期为晚志留世-早泥盆世(424~408Ma)和早-中泥盆世(3.9~3.4Ma)。官坡稀有金属伟晶岩形成于北秦岭碰撞阶段、汇聚减弱-地壳抬升背景和造山后伸展阶段,集中于造山作用晚期。电气石B同位素和锆石Hf同位素组成显示官坡稀有金属伟晶岩来自元古宙陆壳变质沉积岩。官坡稀有金属伟晶岩与区域上出露的花岗岩不具有明显的成因联系,可能为北秦岭单元熔融产物。弱分带火炎沟锡铌钽矿化伟晶岩岩浆就位后未经历明显的分异作用;弱分带锂矿化伟晶岩岩浆是富锂岩浆在其就位后未经历明显的结晶分异即达到锂饱和的沉淀锂矿物,在该体系进入流体阶段后继续沉淀锂矿物完成稀有金属矿化;复杂分带锂矿化或锂铍铌钽铯矿化伟晶岩在岩浆就位后通过结晶分异形成稀有金属饱和熔体,开始沉淀稀有金属矿物,随着熔体和挥发分不断演化,形成富挥发分和稀有金属的熔体,沉淀不同稀有金属矿物组合,并通过碱质流体(部分天水加入)交代进一步完成稀有金属沉淀和再分配。官坡地区稀有金属伟晶岩岩浆的形成过程和岩浆就位后的岩浆-热液演化过程共同完成稀有金属富集成矿。矿物学、岩石地球化学、围岩蚀变和区域构造等方面研究为官坡地区稀有金属伟晶岩找矿提供了潜在的矿化指示标志。
