1Further Information of the Associated Li Deposits in the No.6 Coal Seam at Jungar Coalfield, Inner Mongolia, Northern China显示文摘Total 138 coal samples and 14 parting samples were taken from the No. 6 Seam of the Jungar Coalfield, Inner Mongolia. These samples were analysed by optical microscopy, sequential chemical extraction procedure (SCEP), inductively coupled plasma mass spectrometry (ICP-MS), X-ray powder diffraction (XRD), and scanning electron microscope in conjunction with an energy-dispersive X-ray spectrometer (SEM-EDX) analysis. The results indicate that the Li contents have reached the industrial grade of the coal associated Li deposit, and the total Li reserves have reached 2406600 tons, that is, 5157000 tons Li2O in the No. 6 seam in the Jungar Coalfield. The sequential chemical extraction procedure results suggest that the Li concentration is mainly related to inorganic matter. The minerals in the coals consist of kaolinite, boehmite, chlorite-group mineral, quartz, calcite, pyrite, siderite and amorphous clay material. Some Li could be absorbed by clay minerals in the Li-bearing coal seam. The chlorite phase?could be?most likely the host for a part of Li. The Yinshan Oldland should be the most possible source of Li of the coal.SUN Yuzhuang ZHAO Cunliang LI Yanheng WANG Jinxi ZHANG Jianya JIN Zhe LIN Mingyue Wolfgang KALKREUTH 2013Acta Geologica Sinica(English Edition)2013,87,4:33
2Pollution of organic compounds and heavy metals in a coal gangue dump of the Gequan Coal Mine, China显示文摘Samples around a coal gangue dump of the Gequan Coal Mine were collected in April 2009. GC (gas chromatography) and GC/MS (gas chromatography/mass spectrometry) were employed to analyze the composition of organic matter in the samples. ICP-MS (inductively coupled plasma mass spectrometry) was used to determine the concentrations of heavy metals. The contents of organic extracts are within the range of 140-750 mg/kg. Alkand aro-ratios are relatively high. Compared to those of the background sample (GQ13 ), the contents of saturated hydrocarbon compounds in all the samples are relatively high. The contents of polycyclic aromatic hydrocarbons (PAHs) are relatively high with the distance getting closer to the coal gangue dump. These indicate that organic matter in the samples is from coal particles of the coal gangue dump. The distributions of heavy metals are very similar: the contents decrease with distance from the dump, which indicates that the harmful heavy metals from the coal gangue dump have polluted as thick as at least 500 m.FAN Jingsen SUN Yuzhuang LI Xinyu ZHAO Cunliang TIAN Duanxin SHAO Longyi WANG Jinxi 2013Chinese Journal Of Geochemistry2013,32,3:18
3Anomalous Concentrations of Rare Metal Elements, Rare-scattered(Dispersed) Elements and Rare Earth Elements in the Coal from Iqe Coalfield, Qinghai Province, China显示文摘Total of 23 bench samples were taken from the No. 7 Coal of Iqe Coalfield, Qinghai Province, China, following Chinese Standard Method GB/T 482-2008(2008). These samples were analyzed by powder X-ray diffraction(XRD), inductively coupled plasma mass spectrometry(ICPMS) and X-ray fluorescence(XRF). The results indicate that the No. 7 Coal belongs to a low rank(Ro,ran =0.659%) and high-ash coal(40.54%). Compared to common Chinese and world low-rank coals, the Iqe coal contains anomalous concentrations of rare metal elements, rare-scattered(dispersed) elements and rare earth elements. The highest contents of Rb, Cs, Ga and REY reach to 180, 26, 37, and 397 ppm, respectively. Their average contents of these elements are 10.9, 15, 4.8 and 3.5 times higher than those of world coals, respectively. Minerals in the coal include kaolinite, quartz, muscovite, siderite, and traces of rutile, and brookite. Kaolinite could be main host minerals of Rb, Cs, Ga and REY. The anomalous rare element Rb and Cs accumulation in the Iqe coal is related to both organic and inorganic matter. The REY concentrations may be related to circulation of thermal solutions, contained or sorbed by clayey particles, and organic matter as well.SUN Yuzhuang ZHAO Cunliang LI Yanheng WANG Jinxi 2015Acta Geologica Sinica(English Edition)2015,89,1:12
4China Geological Survey Proved the Existence of an Extra-large CoalAssociated Lithium Deposit显示文摘The most Li deposits were found in lake waters or igneous rock.In recent years,anomalous concentrations of lithium in coal have been reported by several coal geologists(Sun et al.,2010,2012a,2013a;Dai et al.,2012).Some coal geologists argued that these concentrations have economic significance(Sun et al.,2012b,2013b,2014).This discovery has even been reported by Khanchuk et al.(2013)in'The Newsletter of Society for Organic Petrology',and the reportSUN Yuzhuang 2015Acta Geologica Sinica(English Edition)2015,89,1:6

8Highly Configurable Floating-Point FFT IP Core with Reusing Method显示文摘A highly configurable fast Fourier transform intellectual property core (FFT IP core) that can be mounted on Avalon bus of Nios II processor is designed in this paper, by the means of custombuilt components in SOPC Builder. Not only the data number can be configured to 2n and the data width can be configured as integer or floating-point number of 32 bits, but also the number of inner butterfly units is configurable, which can effectively resolve the contradiction between speed and hardware resource occupancy. The IP core is designed by butterfly computing elements of a mixed radix-4 and radix-2 algorithm and applies the inplace addressing scheme and reusing method to reduce hard-ware resources consumption. Functional simulation by Quartus Ⅱplatform proves that the results calculated by FFT IP core are ac-cordant with the Matlab results. Hardware test on DE2 development board by timestamp timer demonstrates that the FFT IP core costs only 34.8 μs to achieve FFT of 512 sampled data with precision of 32-bit floating point. It is demonstrated that the IP core has the advantages of feasible configuration, easy use, and high precision.LIU Sanjun SUN Linjiao LI Shaowu YI Jinqiao MIAO Yuzhuang 2013Wuhan University Journal of Natural Sciences2013,18,1:2
