| 摘 要： | 以淮南煤田潘三煤矿4-2煤层中的岩浆岩、天然焦和煤样品为研究对象,利用X射线衍射仪和X射线荧光光谱仪测试其矿物组成和主量元素含量,研究地下岩浆侵入对煤中矿物成分的影响。结果表明:煤变质成天然焦后,其总的矿物含量增多,并伴随着后生矿物如微斜长石和镁绿泥石的出现。天然焦中后生矿物的组成元素可能来源于岩浆或热液中的主量元素如Si、Al、Na、K、Fe和Mg。

| Abstract: | Taking the magmatic rocks, natural coke and coal samples from coal No.4-2, Panji No.3 coalmine, Huainan coalfield as the subject investigated, using X-ray diffractomcter and X-ray fluorescence spectrometer tested mineral composition and major elements content, studied impacts from magmatic intrusion on mineral components in coal. The result has shown： after coal metamorphosed into natural coke, total mineral content is increased, and accompanied by appearance of epigenetic minerals such as microcline and amesire. The constituent elements of epigenetic minerals in natural coke may come from major elements in magma or hydrothermal solution such as Si, Al, Na, K, Fe and Mg. |
