| 摘要: |
| 热液变质煤与其围岩相比,具有高得多的含脉率。古植物生长具"喜基性成分"的特征。随生物地球化学作用增强,大多数微量金属元素含量升高。随煤变质程度升高,|δ13c|、(002)和(10l)X射线衍射峰的半高宽、红外光谱吸收峰和喇曼光谱散射峰的数目降低,活泼元素的含量、煤结构单元的Lc值和La值增大。 |

| Abstract: |
| The vein-bearing content of hydrothermal metamorphic coal is much greater than that of its wall rock. Paleo-plants possess characteristic of "basicphilic" compone during their growth. The contents of most trace metal elements in coals, such as rare-earth element, indium, copper, molybdenum and nickel,will increase with biogeochemical processes. As the rank of metamorphosed coal is high, the absolute value of σ13c, the widths of halfheight of (002) and (10l) X-ray diffraction peaks, the numbers of ultrared spectral absorption peak and Raman spectral scattered peak will decrease, and the content of active elements, La and Lo of coal texture units will increase. |
