近年我国十大重要金属矿种找矿重大进展与成果

近年我国重要矿产资源勘查成果不断快速涌现。为服务矿产勘查进展长期动态跟踪与成果集成研究,2010~2014年,笔者依托原中国地质调查局发展研究中心承担的《重点成矿区带矿产勘查跟踪与成果集成》、《全国地质勘查进展分析》等项目,以铁、铜、铝、铅锌、金、钨、锡、钼、镍、锰等十大重要金属矿产勘查进展为主要研究对象,研究分析了勘查成果特征。     

更新思路部署促进找矿突破——以云南澜沧铅矿深部超大型斑岩钼(铜)矿发现为例

依据澜沧铅矿2004～2010《全国危机矿山接替资源找矿勘查工作》项目所获,结合以往勘探采矿和科研成果,在原提出“上铅、下铜”金属分带规律的基础上,根据铜矿体下部有矽卡岩化和花岗斑岩脉以及上部铅矿石矿物中有辉钼矿、钨、锡矿化等异常现象,推断深部可能存在钼、锡、钨等的矿化类型(第三矿化带).据此提出“层脉结合,远、近结合,拆墙扩储”的12字找矿新思路,调整工作部署、优选找矿靶区(位),终于在深部发现厚大斑岩型钼(铜)矿体,证实了预测.认为澜沧老厂矿床“三元矿化结构”,实质上是一个完整的斑岩成矿系列,成矿时代为燕山晚期—喜马拉雅早期(始新统晚期为主),矿床成因为与隐伏岩体有关的中偏高温热液矿床.     

初议甘肃省深部找矿

国内外著名的成矿区带和矿床深部引人注目的找矿发现表明了深部找矿的巨大潜力。深部找矿已成为全球勘查的一个主要方向。甘肃省矿产资源具禀赋优势,成矿条件好,找矿潜力大,矿产资源,息体开发程度较高,矿业在全省经济发展中占重要地位。通过分析当前甘肃省矿产资源形势、深部找矿的重要性和可能性,提出了铜、铅、锌、金、钨、钼等矿种的深部找矿地区和项目。认为甘肃省近期要取得找矿的重大突破,必须实施深部找矿（包括矿山、矿集区及具远景的矿床）。     

华南深部找矿有关问题探讨

华南是我国目前最重要的有色金属矿业基地之一。该地区矿业发达但危机矿山也多,研究程度高但多数矿床的勘查工作在20年前就完成,成矿条件好、已发现矿产地点多面广但进一步找矿难度也大。因此,在华南开展深部找矿势在必行,而且受到了国家、地方政府和企业界的共同关注。中国地质调查局设立了湖南瑶岗仙、康家湾、玛瑙山,江西大吉山、荡坪、岿美山,广西佛子冲、铜坑、栗木、泗顶,广东瑶岭、石人嶂、大宝山等一批危机矿山项目,力争在这些矿山深部实现找矿突破。华南地区开展深部找矿需要研究成矿物质来源、矿床分类、成矿区带划分及其在一定深度（距离地表3000m）的变化情况,需要明确地表的战略性选区与点上的攻深找盲、探边摸底同样重要,需要加快中深钻（1000-3000m深度）钻探及相关测量技术的研究,需要通过对“物质不灭”、“能量守恒”和“时空无限但有序”三原则的把握来评价矿产资源的潜力。     

江西赣县区新发现牛角龙钨多金属矿床

根据中国地质调查局总体部署,中国地质调查局南京地质调查中心在赣南地区实施了找矿扶贫工作,“南岭东段重要矿种成矿要素调查”项目组通过1∶5万矿产地质调查、大比例尺填图、地表槽探揭露和深部钻探验证等技术手段,在江西赣县区新发现了具有大型找矿远景的牛角龙钨多金属矿床,不仅实现了赣南找矿空白地区新突破,为赣南地区脱贫致富提供了新的钨矿资源基地,也为赣南及其他地区找矿勘查提供了成功示范和理论依据。     

国土资源部发布指导意见科学规划部署深部找矿

中国地质调查局网站消息国土资源部近日发布了《关于促进深部找矿工作指导意见》,以促进我国固体矿产勘查向深部拓展,实现找矿重大突破。《意见》的主要内容如下： 一是明确深部找矿工作的战略目标。到2020年,发现一批具有宏观影响的深部矿床,显著增加已有矿山接续资源储量,明显延长矿山服务年限。开展主要成矿区带地下500～2000m的深部资源潜力评价,重要固体矿产工业矿体勘查深度推进到1500m。     

The terrestrial fauna of the Late Triassic Pant-y-ffynnon Quarry fissures,South Wales,UK and a new species of Clevosaurus (Lepidosauria: Rhynchocephalia)

Pant-y-ffynnon Quarry in South Wales yielded a rich cache of fossils in the early 1950s, including articulated specimens of new species (the small sauropodomorph dinosaur Pantydraco caducus and the crocodylomorph Terrestrisuchus gracilis), but no substantial study of the wider fauna of the Pant-y-ffynnon fissure systems has been published. Here, our overview of existing specimens, a few described but mostly undescribed, as well as freshly processed material, provides a comprehensive picture of the Pant-y-ffynnon palaeo-island of the Late Triassic. This was an island with a relatively impoverished fauna dominated by small clevosaurs (rhynchocephalians), including a new species, Clevosaurus cambrica, described here from a partially articulated specimen and isolated bones. The new species has a dental morphology that is intermediate between the Late Triassic Clevosaurus hudsoni, from Cromhall Quarry to the east, and the younger C. convallis from Pant Quarry to the west, suggesting adaptive radiation of clevosaurs in the palaeo-archipelago. The larger reptiles on the palaeo-island do not exceed 1.5?m in length, including a small carnivorous crocodylomorph, Terrestrisuchus, and a possible example of insular dwarfism in the basal dinosaur Pantydraco.     

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.

The effect of water on accessory phase solubility in subaluminous and peralkaline granitic melts

The solubilities of columbite, tantalite, wolframite, rutile, zircon and hafnon were determined as a function of the water contents in peralkaline and subaluminous granite melts. All experiments were conducted at 1035 °C and 2 kbar and the water contents of the melts ranged from nominally dry to approximately 6 wt.% H₂O. Accessory phase solubilities are not affected by the water content of the peralkaline melt. By contrast, solubilities are affected by the water content of the subaluminous melt, where the solubilities of all the accessory phases examined increase with the water content of the melt, up to 2 wt.% H₂O. At higher water contents, solubilities are nearly constant. It can be concluded that water is not an important control of accessory phase solubility, although the water content will affect diffusivities of components in the melt, thus whether or not accessory phases will be present as restite material. The solubility behaviour in the subaluminous and peralkaline melts supports previous spectroscopic studies, which have observed differences in the coordination of high field strength elements in dry vs. wet subaluminous granitic glasses, but not for peralkaline granitic glasses. Lastly, the fact that wolframite solubility increases with increasing water content in the subaluminous melt suggests that tungsten dissolved as a hexavalent species.     

Late Wuchiapingian (Late Dzhulfian,early Late Permian) limestone olistolites within the Tertiary flysch of Glypia Unit (Mount Parnon,central–eastern Peloponnesus,Greece)

Some olistolites reworked in a Tertiary flysch of Mount Parnon (Peloponnesus, Greece) exhibit a Late Permian assemblage, dominated by Paradunbarula (Shindella) shindensis, Hemigordiopsis cf. luquensis and Colaniella aff. minima. This association corresponds to the Late Wuchiapingian (=Late Dzhulfian), a substage whose algae and foraminifera are generally little known. Contemporaneous limestones crop out in the middle part of the Episkopi Formation in Hydra, but they are rather commonly reworked in Mesozoic and Cainozoic sequences. The palaeobiogeographical affinities shared by the foraminiferal markers of Greece, southeastern Pamir, and southern China, are very strong (up to the specific level), and are congruent with the Pangea B reconstructions.
