| 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. |

| Keywords: | coal metamorphism hydrothermal vein petrological characteristics |
