中文摘要:
      为探讨煤样品中主量元素和微量元素的差异性及其控制因素,以处于同一构造背景下南疆三地州三个盆地内的煤矿为研究对象。通过反射光显微镜、带能谱的扫描电镜(SEM-EDS)等分析测试方法,对比分析长胜(CS)煤矿、克孜库尔安(KZKEA)煤矿和莫木太来克(MMTLK)煤矿煤样品主量元素和微量元素特征的差异性。利用微量元素,如钒/(钒+镍)(V/(V+Ni))、锶/铜(Sr/Cu)和锶/钡(Sr/Ba)等比值,分别探讨了三个煤矿沉积时期的氧化还原特征、古气候和古盐度特征。研究结果表明,泥炭沼泽形成时的沉积环境和构造运动是引起同一构造背景下三个盆地煤中元素差异的主要因素。
英文摘要:
      In order to explore the di.erences between major and trace elements in coal samples and their controlling factors, the coal mines in the three basins of Sandi Prefecture, southern Xinjiang under the same structural background are taken as the research objects. Through analysis and testing methods such as re.ected light microscope and scanning electron microscope with energy spectrum (SEM-EDS), the coals of Changsheng (CS) Coal Mine, Kezikueran (KZKEA) Coal Mine and Momutaileike (MMTLK) Coal Mine were compared and analyzed. The di.erence in the characteristics of the main elements and trace elements of the sample. Using trace elements, such as the ratio of V/(V+Ni), Sr/Cu and Sr/Ba, the three coal mines Redox characteristics, paleo-climate and paleo-salinity characteristics during deposition. The research results show that the sedimentary environment and tectonic movement when the peat swamp was formed are the main factors that cause the di.erences in the elements in the coals of the three basins under the same tectonic background.
