中文摘要：
由于煤层是软弱岩层，岩浆作用易在煤层及其附近侵入，从而使煤层受热力作用增强，其中一些敏感性微量元素发生迁移、转化等复杂的地球化学过程。本项目以两淮煤田为例题，通过对岩浆岩、岩浆与煤层混合带以及正常煤层等样品中微量元素的含量分布规律、精细化学结构以及部分元素的同位素值测试与研究，分析岩浆岩与煤层中微量元素的相互作用关系，微量元素的影响因素及转化过程，为煤矿开采和煤中微量元素的综合利用提供科学资料。

结论摘要：
煤是中国最重要的能源之一，同时煤中赋存多种微量元素，在特殊的地质条件下可能异常富集，形成共伴生矿床或产生环境危害。本课题主要以两淮煤田为例，选取不同沉积环境及地质构造背景下的煤为研究对象，综合煤岩学、沉积学、矿物学和元素地球化学理论，测试煤中微量元素含量，与煤中相应元素的背景值比较，确定异常富集的元素；根据对典型样品的分析，揭示岩浆侵入、区域地质构造（断层、背向斜和褶皱）与元素异常富集的关系，并结合显微煤岩组成、碳、硫和汞同位素数据，反演煤的沉积环境，进而归纳出煤中微量元素异常富集机理和地球化学成因模式，为煤中潜在的共伴生矿产资源利用和环境保护提供理论依据。
