摘要: |
详细讨论了广西早奥陶世、早石炭世、晚二叠世煤中热液脉体的种类、岩石学特征及其与煤变质程度的关系。无论什么时代的无烟煤,随着其变质程度升高,煤中脉体种类增多,矿物成分变得复杂,较高温热水矿物出现。 |

Abstract: |
It is an important evidence of coal hydrothermal metamorphism that hydrothermal veins with highly vein-bearing content are found in coals. Hydrothermal veins were discussed on their types, petrological characters and the relations to coal ranks in Early Ordovician, Early Carboniferous and upper permian in Guangxi.The types of veins increase, the mineral components get more complicated and higher temperature hydrothermal minerals evolve as the anthracite metamorphic ranks,whenever they are,get higher. |
Key words: coal metamorphism hydrothermal vein petrological characteristics |
