| 1 | 内蒙古自治区胜利煤田锗矿地质及分布规律显示文摘介绍了胜利煤-锗矿床的地质背景,以及锗在矿层的分布情况.胜利煤田处于二连盆地东端乌尼特坳陷中,为一宽缓向斜,地层平缓.胜利煤田煤-锗矿床发育于早白垩世断陷盆地内,位于二连盆地群中胜利煤盆的西南一隅,富锗矿层的分布受两侧F1,F2断层影响,呈现南部埋藏浅厚度薄、北部埋藏深厚度大的倾斜状特点;锗品位变化为南、北部较高(>400×10-6),东、西部较低(200×10-6左右)的'鞍'状分布特点,而向盆地中心急剧降低.沿煤层纵向上可以出现多个聚锗高值,个别钻孔煤层下部夹矸锗含量超过工业品位而具有工业价值,而煤层顶、底板锗含量都很低(<10×10-6),不具有工业价值.锗的分布,与成矿古地质、环境变化有关,受沼泽微环境和水动力影响,锗在煤层中的富集出现波动.采用'地质块段法'估算锗煤的资源量,资源量估算面积1.097 5 km2,估算结果锗资源量1 805 t. | 黄文辉 孙磊 马延英 万欢 唐修义 杜刚 武文 秦胜利 Robert B.Finkelman | 2007 | 煤炭学报2007,32,11: | 25 |
| 2 | Coal petrology and genesis of Jurassic coal in the Ordos Basin,China显示文摘简单结构和浅埋葬深度描绘的厚煤床的多重集合在 Ordos 盆的早、中间的侏罗记阶层被开发,西北的中国。这高质量的煤的巨大的储备有高商业的价值。我们学习了煤岩石学的特征和它的 maceral 分发到决定 macerals 贡献到油和气体的产生。结果证明因为主要是在上面的河的系统的一系列高看台的沼泽地的盆唯一的 depositional 环境,在 Ordos 盆的侏罗记煤有特殊 petrological 特征。这些 petrographic 特征是一些沙身体被移植河形成的典型内陆湖的发展的结果。在埋葬以后,泥炭继续经历氧化条件,产生广泛的更高的 inertinite 在煤满足的这个过程和 vitrinite 部件被改变到 semi-vitrinite。这些侏罗记煤的宏观的 petrographic 类型主要是半迟钝的煤,迟钝的煤, semilustrous 和有光泽的煤。半迟钝的煤和迟钝的煤的比例在盆边缘是更高的,特别在北边缘附近的区域。semilustrous 和有光泽的煤的数字向南并且向中央盆增加。这种状况显示不同形成煤的沼泽地环境让学生在煤部件上控制效果。另一观察是在 Ordos 煤序列,特别在更低的部分,一些沙岩床是厚的,直到有一种粗糙的谷物尺寸的 20 m。在 macerals 的更高的 fusinite 内容与更多的完全、常规的植物房间结构伴随一个更高的 semi-vitrinite 内容。fusinite 结构清楚、很好保存。在埋葬以后,房顶和地板岩石的岩性学能继续影响煤岩石学的进化。在房顶和地板的沙身体展出好物理条件以便毛孔水能维持氧化,循环和连接的一个长期的状态到煤。煤部件因此很长时间留在氧化环境。在盆中心,在埋葬和随后的煤床很快进入了减少的环境以后,相反地,开发的湖的外形和泥炭被 mudstone 很快盖住。作为结果,丰富的胶凝化作用发生了, vitrinite 内容增加了。Exinite 经常在煤床上在一个特定的位置积累了。尽管平均 exinite 内容不总体上高,它显著地确实贡献全部的烃产生。exinite 内容被低估了,特别非结晶的沥青的液体和它的重要性这里被强调。原因是液体容易流进有强壮的刚硬的 fusinite,或流进一些裂缝,在它通常被忽视的地方。 | Weihua Ao Wenhui Huang Chengmin Weng Xiuling Xiao Dameng Liu Xiuyi Tang Ping Chen Zhigen Zhao Huan Wan Robert B.Finkelman | 2012 | Geoscience Frontiers2012,3,1: | 3 |
| 3 | Distribution of rare earth elements in PM10 emitted from burning coals and soil-mixed coal briquettes显示文摘Emission from burning coals is one of the major sources of the airborne particles in China.We carried out a study on the rare earth elements(REEs)in the inhalable particulate matter(PM10)emitted from burning coals and soil-coal honeycomb briquettes with different volatile contents and ash yields in a combustion-dilution system.Gravimetric analysis indicates that the equivalent mass concentration of the PM10 emitted from burning the coals is higher than that emitted from burning the briquettes.The ICP-MS analysis indicates that the contents of total REEs in the coal-burning PM10 are lower than those in the briquetteburning PM10.In addition,the contents of the light rare earth elements(LREEs)are higher than those of the heavy rare earth elements(HREEs)in the PM10 emitted from burning the coals and briquettes,demonstrating that the REEs in both the coal-burning and briquetteburning PM10 are dominated by LREEs.The higher contents of total REEs and LREEs in the coal-burning PM10 are associated with the higher ash yields and lower volatile contents in the raw coals.A comparative analysis indicates that the La/Sm ratios in the PM10 emitted from burning the coals and briquettes,being lower than 2,are lower than those in the particles from gasoline-powered vehicle emission. | Longyi Shao Lingli Chang Robert B.Finkelman Wenhua Wang Junxia Liu Jie Li Jiaoping Xing Cong Hou 无 | 2020 | Journal of Environmental Sciences2020,32,11: | 0 |
| 4 | Guizhou Province, China: the birthplace of modern Medical Geology显示文摘Medical Geology,the emerging discipline that focuses on the health impacts of geologic materials and geologic processes,has its roots in Guizhou Province,China.In the 1980 s Prof.Zheng Baoshan and his students recognized that a large number of people in Guizhou Province had clinical symptoms of arsenic poisoning,fluorine exposure,selenosis,and other diseases caused by exposure to potentially toxic trace elements or due to deficiency of essential elements.Their publications and invitations to scientists to visit the Province ultimately resulted in increased attention to the health impacts of the natural environment and the formation of scientific societies,the publication of at least a dozen books,and thousands of technical articles on what is now called Medical Geology. | Robert B.Finkelman Jose A.Centeno | 2020 | Acta Geochimica2020,39,1: | 0 |
| 5 | The future environmental and health impacts of coal显示文摘In the United States,coal consumption in the last 12 years has declined from 1,045,140 million short tons in 2007 to 539,420 million short tons in 2019,a decrease of almost 50%.During that period the number of electric power coal generators has declined from 1,470 to 738 accounting for 21%of capacity.An even more dramatic decrease in coal use has occurred in Western Europe.This significant reduction in coal use and the concomitant closure of coal mines and coal-burning power plants will result in substantially cleaner air,reductions in respiratory problems such as asthma,less heart disease,fewer hospitalizations,and other health benefits,as well as a reduction in occupational health problems such as silicosis and Coal Workers’Pneumoconiosis(Black Lung Disease).However,in China,India,Russia and in several other Asian countries some projections indicate an increase in coal production and use.In some situations,the coal is burned in old,highly polluting power plants.In these regions the health impacts of coal use could worsen.In addition,millions of people in these regions still burn coal in their homes resulting in maximal exposure to the pollutants such as arsenic,selenium,fluorine,and mercury released from coal combustion. | Robert B.Finkelman Amy Wolfe Michael S.Hendryx | 2021 | Energy Geoscience2021,2,2: | 0 |
