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 （ICP- MS） and X-ray fluorescence （XRF）. The results indicate that the No. 7 Coal belongs to a low rank （*** =0.659%） and high-ash coal （40.54%）. Compared to common Chinese and world low-rank coals, the lqe 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.

Generally, sandstone-type uranium deposits can be divided into three zones according to their redox conditions: oxidized zone, ore zone and reduced zone. The Dongsheng uranium deposit belongs to this type. In order to study its geochemical characteristics, 11 samples were taken from the three zones of the Dongsheng uranium deposit. Five samples of them were collected from the oxidized zone, four samples from the ore zone and two samples from the reduced zone. These samples were analyzed using organic and inorganic geochemical methods. The results of GC traces and ICP-MASS indicate that the three zones show different organic and inorganic geochemical characteristics.

The Fankou Pb-Zn deposit is a very important and famous deposit in China. The time of Pb-Zn enrichment has been debated for a long time in this deposit. A total of seventeen samples of three sections were taken from the Fankou mine for the study of mineralization time and the mechanism of ore formation. The samples were analyzed by microscope, Soxhlet-extract, GC, and GC/MS methods. The results indicated that organic bulk parameters vary with the Pb-Zn contents in different samples and clearly were influenced by ore sulfide formation. Organically geochemical parameters (MPI 1, CPI) indicate that the paleotemperatures in the Fankou deposit are lower than 80℃ in all three sections. Sulfides in the wall rocks might occur mainly during synsedimentation or early diagenesis by BSR or partly by PR, rather than by TSR at such low temperatures, this stage may be the first mineralization stage. Sulfides near the faults might be formed by TSR after sedimentation, this stage may be the second mineralization stage.

Ltd.of China Electronics System Engineering The Land and Resources Department of Wu'an

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.

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.

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 report was reprinted by the Geospectrum of the American Geosciences Institute （Geospectrum, 2014）.

【研究目的】野火是陆地生态系统的一个重要组成部分,燃烧产生的温室气体会对气候环境产生影响。对地史时期古野火的研究可以获得野火对生态系统的潜在长期影响。【研究方法】采集了鄂尔多斯盆地侏罗纪延安组5个主采煤层的56个样品,并对其进行了宏观煤岩观察、煤岩显微组分定量、惰质组反射率测定、微观形貌观察。【研究结果】结果显示在煤层的顶底板中存在大量的宏观化石木炭(Charcoal),且细胞间层均为同质化;煤中惰质组含量分布范围为45.23%~56.81%,且大部分惰质组反射率低于2%。【结论】这表明在泥炭沉积时期发生过高频率的野火事件且以中低温的地表火为主。根据现代森林火灾碳排放模型和煤中的惰质组由燃烧成因理论,计算出仅在鄂尔多斯盆地延安组泥炭系统中野火释放的总碳量为443 Gt,其中CO_(2)的量为1377 Gt,CO的量为86.7 Gt,CH_(4)的量为8.2 Gt,CO_(2)的释放量相当于目前大气圈中CO_(2)总量的45.9%。延安组时期陆地生态系统中野火释放的巨量温室气体可能是导致这一时期气候变暖的原因之一。
