Rare Earth Elements Compositions and Genesis of Xinhua Large-Scale Phosphorite Deposit in Western Guizhou, China

Zhijin County in Western Guizhou is one of the most important production areas of phosphorites in China. In order to investigate genesis of the phosphorites, their REE compositions were analyzed by using inductively coupled plasma emission mass spectrometry (ICP-MS) method. For comparison, phosphorites from the Lower Cambrian black rock series in Southern China, such as Zunyi in Guizhou and Zhangjiajie in Hunan Province, were also analyzed. The analytical data show that: (1) Xinhua phosphorites possess a quite high and greatly varied total rare earth elements (ΣREE), which varying between 164.23×10-6 and 1395.01×10-6 with average of 642.54×10-6, remarkable differentiation between light (LREE) and heavy rare earth elements (HREE), and the ΣLREE/ΣHREE ratios varying between 5.04 and 6.52. The ΣREE and ΣLREE/ΣHREE ratios of the Zunyi and Zhangjiajie phosphorites are 156.69×10-6～637.41×10-6 with average of 431 75×10-6 and 3.17～6.95 with average of 4.37 respectively; (2) All the phosphorites from Xinhua, Zunyi and Zhangjiajie show remarkable negative Ce anomalies. Besides, the Xinhua phosphorites possess lower δCe, which varying between 0.26 and 0.53 with average of 0.35, while δCe of the Zunyi and Zhangjiajie phosphorites are 0.30～0.66 with average of 0.47, suggesting that all of the phosphorites are typical marine sediments deposited mainly in ancient peri-continental seas, and the depositional position of the Xinhua phosphorite might be deeper; (3) Most phosphorites from Xinhua, Zunyi and Zhangjiajie possess unremarkable positive Eu anomaly, and only a few of samples show obvious ones. The δEu varies between 0.98 and 2.4, suggesting that hot (>200 ℃) and strong reductive hydrothermal fluids might have been involved in genesis of the phosphorites; (4) The Xinhua phosphorite is relatively depleted in HREE, and LaN/NdN and δY of most samples are >1 and >1.5 respectively. Besides, there exists no correlation between δY and δCe, suggesting that the phosphorite was subjected to quite strong weathering and leaching processes, and catagenesis do not greatly modify its REE compositions.

Human Driving Forces:Analysis of Rocky Desertification in Karst Region in Guanling County,Guizhou Province

Karst rocky desertification is one of the major ecological and environmental problems that threaten the sustainable development of southwestern China. It is caused by irrational and intensive land-use patterns in karst geo-ecological environment. Therefore, it is vital to identify how human forces work on this degraded environment. Based on the soil erosion information in 2000 and remote sensing images of Guanling County collected in 2000 and 2007, four grades of karst rocky desertification data in 14 villages of Guanling County were extracted. Impacts of population, affluence, and other human forces on karst rocky desertification were analyzed using STIRPAT model. The results show that:1) Factors of population and affluence had strong influence on karst rocky desertification. In the STIRPAT model analysis, the population and affluence coefficients were positive, indicating that the increase in population and affluence would lead to more serious desertification. 2) Factors of farmer correlated with karst rocky desertification negatively, especially the way of viewing the relationship between people and nature, and the level of knowledge about rocky desertification. Government behavior was not a significant factor in this analysis. 3) The findings provide evidence that STIRPAT model can be used to analyze the relationship between human driving forces and rocky desertification.

Factor Capitalization,Industry Development and Targeted Poverty Alleviation——Based on the Investigation of Danzhai County,Guizhou Province

At present,targeted poverty alleviation is a major development strategy in China.Based on the investigation of Danzhai County in Guizhou Province,this paper argues that industry development is the fundamental measure through which to implement the poverty alleviation program.Industry development includes both the development of local industries in povertystricken areas and the development of industries in other regions of China.Local development is mainly achieved when the invisible superior resources become visible and the notable superior resources are capitalized in povertystricken areas,in which,the capitalization of factors and resources relies on fundamental governmental investments which will create a profit space for the poverty-stricken areas through the down-to-countryside cadres' precise guidance for the use of poverty alleviation funds to help identify a breakthrough for industry development,and particularly the attempts to focus on the development of high-end industries under the lower-end production mode to form a community with common interests aiding poverty alleviation.Development in other regions can be mainly achieved through various modes such as "tax-finance-poverty alleviation," "industry-employment-poverty alleviation" and "industry-enterprise direct investment-poverty alleviation" to offer indirect or direct support for poverty alleviation in poverty-stricken areas.An appropriate handling is required to deal with many problems related to the local industry development in targeted poverty alleviation and the targeted poverty alleviation in industry development.

Emplacement Ages and Geochemical Characteristics of Grabbroic Intrusions and Prospecting Orientation of Related Deposit in Luodian,Guizhou Province

Emplacement ages, geochemical characteristics and analysis of continental dynamics on gabbroic intrusions in Luodian County, Guizhou Province, have been discussed based on studies of isotopic chronology （the whole-rock Sm-Nd and Rb-Sr isochron methods）, major elements, trace elements and PGE. Intrusive activities of the gabbroic intrusions in the study area took place during the Late Yanshanian Orogenic Movement （the Cretaceous Period）, as indicated by the Sm-Nd isochron ages （t）=（99.6±4.5） （2σ） Ma and by the Rb-Sr isochron ages t=（97±1.6） （2σ） Ma. The gabbroic intrusions are attached to mafic rocks in cal-alkaline basaltic series. They occurred as dikes and might be formed under an extensional background of the continent. Differentiation of their magmatic crystallization resulted in obvious zonation of petrography. In the gabbroic intrusions of this study, large ion lithophile elements and LREE are enriched, and the chondrite-normalized REE distribution pattern is leftward inclined without anomalies of JCe or JEu, and there are high concentrations of PGE and ratios of Pd/Ir （averaging 4.21）. All of these imply that their source areas may be basaltic magma in the upper mantle with high-level partial melting, derived from EMl-type enriched mantle. It is different from Emeishan basalt, which may be related to the upper mantle at low-grade partial melting. Emplacement mechanism of the gabbroic intrusions in this study may suppose to be asthenosphere upheaving as an isolated hot wave in the presence of mantle fluid, resulting in basaltic magma intruded into the continental crust as a diapiric intrusion. Therefore, uplifting of faulting-block and extensional deformation could take place in the shallow part of the continental crust while vertical amassing and accretion of magmatic materials in the deep part of the continental crust. These special processes could supposed to be a special background of continental dynamics for this large-scale epithermal metallogenic domain, such as Au, As, Sb and Hg deposits, and vertical uplifting of the Yunnan-Guizhou Plateau in the Cretaceous Period.

贵州兴义普克金矿区土壤地球化学异常特征及找矿方向

贵州省普克金矿区位于著名的黔西南泥堡金矿西南方向的外围区域,与泥堡金矿处于相同的大地构造环境,地层特征、构造样式基本相同,成矿地质条件良好,且早期120万水系沉积物地球化学测量成果显示普克金矿区内Au、Sb、As异常区域呈现较好的重叠关系。为进一步缩小找矿工作范围,文章通过在普克金矿区开展11万土壤地球化学测量,在统计分析12个被测元素变化系数、富集离散程度的基础上,结合聚类分析、相关分析、因子分析揭示元素组合规律,结果表明As、Sb、Cu、Hg等元素是区内寻找金矿的重要指示元素。文章采用平均值±3倍标准差的方法确定各元素的异常下限,并据此在普克金矿区内圈定了4处找矿指示元素叠加异常区域(HS-1~HS-4),其中有利找矿靶区2处。研究结果揭示了土壤地球化学在本区找矿的有效性。

贵州关岭地区法郎组瓦窑段菊石类新材料

本文对采自于贵州关岭地区上三叠统卡尼阶法郎组瓦窑段上部的齿菊石目化石进行了研究,共识别出3属3种,其中包含一新种Arctosirenites mingqingensissp.nov.。Arctosirenites mingqingensis sp.nov.以具有细密横肋及粗壮腹缘瘤为特征,属Klipsteinia在华南为首次发现。根据Klipsteinia和Arctosirenites组合特征判断贵州关岭地区上三叠统法郎组瓦窑段底部时代为晚三叠世早卡尼期早期(Julian 1),上部时代归属于晚卡尼期早期(Tuvalian 1),并且认为造成法郎组瓦窑段底部的岩性变化是由于构造因素导致,而并非受到卡尼期湿润幕事件(CPE,Carnian Pluvial Episode)的影响。

织金县苗族射弩的历史源流、价值彰显与纾解路径

文章运用文献研究法、历史研究法、逻辑思辨法等研究方法,以贵州织金县苗族射弩为例,就苗族射弩的历史源流、价值彰显、发展困境进行梳理,并对其未来发展纾解路径进行探索性研究。分析得出织金苗族射弩具有丰富业余生活、强身健体、促进经济增长、拓宽教育、增进民族认同、推动文化交流、保留历史痕迹等价值。现实困境:苗族射弩“边缘化”;现代化进程中缺乏民族文化认同导致传承人流失;西方竞技体育文化的涌入导致苗族射弩被冷落;学校体育教育的现代化价值取向导致传承路径中断。基于此,提出政府监管、文化自觉、体旅结合和教育传承等发展策略。

贵州三穗龙湾大型铀矿床铀的赋存状态和地球化学研究

贵州三穗县龙湾铀矿床是近年勘查发现的大型铀矿床,矿体呈层状、似层状产于震旦-寒武系老堡组黑色岩系中。前人对该矿床开展了矿床地质和地球化学研究,但铀的赋存状态、成矿物质来源和成矿环境尚不明确。本文选取龙湾矿床南部的老棚剖面为研究对象,开展矿物学和全岩元素地球化学研究。研究结果表明铀主要以沥青铀矿和钛铀矿等的独立铀矿物形式存在于磷灰石矿物边缘、裂隙及孔洞处,部分以类质同象形式赋存于磷灰石的晶格中。全岩地球化学分析结果显示样品Y/Ho值为16.3~63.2(均值为40.3),Zr/Hf值为33.6~79.3(均值为42.3),靠近上地壳的值;样品具有相对平坦的稀土元素配分模式,显示无-弱Eu正异常(δEu为0.27~1.19,均值为0.82);硅质岩Ge/Si值为1.23×10^(-6)~0.15×10^(-6)(均值为0.47×10^(-6)),均接近现代海水平均值,表明龙湾铀矿床成岩成矿物质来源主要为陆源风化碎屑物质,受到海底热水作用的影响小。样品V/(V+Ni)值为0.43~0.98(均值为0.80),Ni/Co值为1.80~58.0(均值为12.7),具有明显Ce负异常(δCe值为0.31~0.81,均值为0.60),表明龙湾铀矿床形成于还原沉积环境中。综合研究表明,在新元古代晚期-晚古生代早期,黔东地区大陆风化作用为海洋提供了铀,在还原条件下形成龙湾黑色岩系型铀矿床。
