Integrated geochemical and Sr-Nd-Pb isotopic studies of the Early Jurassic Nandaling flood basalts(NFB) in the Yanshan belt, northern margin of the North china Craton(NCC),are presented in this *** sub-alkaline basalts evolved from a more magnesium-rich parental magma through fractional crystallization of olivine and *** primitive magma of the NFB originated from 2-5%partial melting of spinel to garnet transitional peridotite at about 70-80 km depth in the Mesozoic lithosphere *** NFB contain a distinctive lithospheric component,characterized by Nb(Ta),Th,U and Ti depletions,LREE enrichments, moderate Sr,and low Nd and Pb initial isotopic ratios,as a result of an interaction between lower crust(15-25%) and primitive magma evoked by magmatic underplating at crust-mantle *** Early Jurassic NFB extruded in an intraplate extensional setting related to post-orogenic collapse in the northern margin of the NCC,indicating an event of lithospheric modification earlier than that in the southern margin(Early Cretaceous).The temporal similarity of the Jurassic-Cretaceous mantle-derived mafic rocks to lower crust replacement,and the decoupling of surface shortening with lithospheric thinning during the Late Jurassic-Early Cretaceous, suggest the important role of magmatic underplating and subsequent crust-mantle interaction accompanied by asthenosphere upwelling on the evolution of the Mesozoic lithosphere of the *** correlation between lithospheric thinning and magmatic underplating may be an important process in continental rifting.

The soil organic carbon (SOC) pool is the largest component of terrestrial carbon pools. With the construction of a geographically referenced database taken from the second national general soil survey materials and based on 154. typical cropland soil profiles, the paddy field and dryland SOC storage among six regions of china were systematically quantified to characterize the spatial pattern of cropland SOC storage in china and to examine the relationship between mean annual temperature, precipitation, soil texture features and SOC content. In all regions, paddy soils had higher SOC storage than dryland soils, and cropland SOC content was the highest in Southwest china. Climate controlled the spatial distribution of SOC in both paddy and dryland soils, with SOC storage increasing with increasing precipitation and decreasing with increasing temperature.

Acta Oceanologica Sinica 2009年第3期28卷 26-39页

作者： LIU Hailing XIE Guofa LIN Qiujin ZHENG Hongbo LIU Yingchun Key Laboratory of Marginal Sea Geology South China Sea Institute of OceanologyChinese Academy of Sciences Guangzhou 510301 China Brigade 261 Bureau of Nuclear Geology Jiangxi Province Yingtan 335001 China

Layer-block tectonics （LBT） concept, with the core of pluralistic geodynamic outlook and multilayer-sliding tectonic outlook, is one of new keys to study 3-dimensional solid and its 4.dimensional evolution history of global tectonic system controlled by global geodynamics system. The LBT concept is applied to study the lithospheric tectonics of the southern South china Sea （SCS）. Based on the analysis of about 30 000 km of geophysical and geological data, some layer-blocks in the Nansha micro-plate can be divided as Nansha ultra-crustal layer-block, Zengmu crustal layer-block, Nanwei （Rifleman bank）-Andu （Ardasier bank） and Liyue （Reed bank） North Palawan crustal layer-blocks, Andu-Bisheng and Liyue-Banyue basemental layer-blocks. The basic characteristics of the basemental layer-blocks have been dicussed, and three intra-plate basin groups are identified. The intra-plate basins within Nansha micro-plate can be divided into three basin groups of Nanwei- Andu, Feixin-Nanhua, and Liyue-North Palawan based on the different geodynamics. In the light of pluralistic geodynamic concept, the upheaving force induced by the mid-crust plastic layer is proposed as the main dynamical force which causes the formation of the intra-plate basins within the Nansha micro-plate. Finally, models of a face-to-face dip-slip detachment of basemental layerblock and a unilateral dip-slip-detachment of basemental layer-block are put forward for the forming mechanisms of the Nanwei Andu and Liyue-North Palawan intra-plate basin groups, respectively.

Journal of Mountain Science 2011年第5期8卷 694-703页

作者： TAO Zhen GAO Quanzhou GUO Wenping WANG Zhengang ZHANG Yongling XIE Chenji HUANG Xiakun ZHONG Hongwei School of Geography and Planning and Guangdong Key Laboratory for Urbanization and Geo-simulation Sun Yat-sen University Guangzhou 510275 China Wuzhou Branch Guangxi Regional Hydrological and Water Resources Bureau Wuzhou 543002 China Makou Hydrological Gauge Station Guangdong Province Hydrological Bureau Foshan 528100 China

A whole year analysis of riverine dissolved organic carbon (DOC) concentrations in the Xijiang River (XJR), South china, showed that the mean riverine DOC concentration (1.24.mg L-1) in the XJR was notably lower than the averaged value (5.75 mg L-1) of the global riverine DOC concentration in several major rivers. There is an inconspicuous monthly fluctuation of the DOC signal in the XJR, but on a semi-yearly time scale, however, the riverine DOC concentration had significant difference between hydrological seasons. The DOC level during the flood season (1.18 mg L-1) was less than that during the non-flood season (1.4. mg L-1). Owing to the concomitance of the flushing and dilution effects of the runoff during the high-water period, the variation of riverine DOC concentration with discharge in the XJR differed from that reported in many other major rivers. The DOC export flux above the city of Wuzhou was about 0.62× 106 g C km-2 yr-1. The DOC transported during the "056" Massive Flood period comprised 30.35% of the annual total, while the discharge accounted for 36.32% of the total annual flow. The characteristics in riverine DOC concentration in the XJR were attributed to the combined effect of the geomorphologic, monsoon climatic and hydrological processes as well as land-use within the drainage basin.

分析了取自福建沿海农田185件表层土壤样品的重金属含量与分布特征,采用连续提出的方法研究重金属元素的赋存状态。结果表明福建沿海稻田土壤中的Hg、Cd、As、Cr、Ni、Cu、Zn和Pb的平均含量分别为0.4.mgkg-1、0.20mgkg-1、6.62mgkg-1、35.65mgkg-1、12.7mgkg-1、128.39mgkg-1、109.65mgkg-1和63.56mgkg-1。相对于区域土壤背景值与国家土壤环境质量标准,污染较突出的元素是Hg和Cd。有4.%样品中的Hg含量高于土壤质量的Ⅱ标准值,有13%的样品的Cd高于土壤质量的Ⅱ标准值。Hg高含量的样品主要分布福州、漳州等城镇等附近,同时它在土壤中主要以有机结合态的形式存在,土壤中Hg含量的升高可能主要来自于后期污染的叠加。Cd高含量的样品的分布则较分散,并不都集中在工业活动区,同时它在土壤中是以残渣态和铁锰氧化物态的形式存在,说明其高含量可能更多是受到成土母质的地球化学背景影响。农田土壤中的Hg和Cd具有较高的生态风险。该区主要是栽种水稻,而水稻对Cd具有强吸收的特性,土壤酸化还会促进Cd的吸收。本区土壤呈酸性,所以Cd污染可能导致大米的食品安全应引起足够重视。
