摘　　要：煤是我国的主要能源,煤炭大量使用会造成一系列环境问题,特别是煤中伴生的有害微量元素迁移、析出,进而影响人类生存生活环境.关于煤中微量元素的研究已经形成了相对完整的体系,然而,由于腐泥煤的次要经济地位,其微量元素地球化学研究远不如腐植煤.腐泥煤分布广泛、厚度大,具有一定的工业价值,腐泥煤中微量元素含量特征已有部分报道,而对腐泥煤中微量元素的赋存状态、富集机理、地质成因等地球化学机理方面有待系统研究.在综合分析国内外腐泥煤研究基础上,详细阐述了腐泥煤中微量元素地球化学研究的热点问题、重点内容和发展方向.腐泥煤的地球化学研究是对煤地质学和煤地球化学理论的补充和完善,具有重要科学意义,对我国特殊煤种成煤理论体系和资源开发利用亦具重要现实意义.Coal is the main energy source in China whose extensive use will cause a series of environmental problems,especially the migration and precipitation of its harmful trace elements.Although there is already a relatively complete research system of trace elements in coal,its trace element geochemistry research is far less developed than that of humic coal,due to the secondary economic status of sapropel.The extensive and thick distribution of sapropelic coal gives it a certain industrial value,and the content characteristics of trace elements in sapropelic coal have been partially reported.However,the modes of occurrence,enrichment mechanism and geological origin of trace elements in sapropelic coal need to be systematically studied.Therefore,based on the comprehensive analysis of domestic and foreign research on sapropel,this paper elaborates the hot issues,key contents and development direction of trace element geochemistry of sapropel.The geochemical research on sapropel is a supplement and improvement of coal geology and coal geochemistry theory,which has important scientific significance,It is also of great practical significance as its beneficial to the theoretical system of coal formation and resource development of special coal in China.
