| 摘 要： | 本文在较大量和详细的煤岩煤质研究之后，进而用电子探针、扫描电镜及显微镜热台等对宁夏汝箕沟无烟煤中矿物的分成、晶形、微量元素、包裹体温等进行了成因研究。结果表明，汝箕沟煤中的次生矿物及原生矿物的次生变化均与中－低温热液作用有关，这将为该区煤变质成因提供直接证据。

| Abstract: | On the basis of coal petrology and chemistry, this paper further deals with the composi-tions, crystal forms, trace elements and inclusion temperatures of minerals from anthracite atRujigou, Ningxia, by using electron microprobe (EPA), SEM and thermometry. The resultsshow that the occurrence of secondary minerals and secondary changes of primary mineralsare all related to moderate-low temperature hydrothermal activities. This will provide directevidence for the metamorphogenesis of coal. |
