摘要
对柳江火山－构造盆地中的火山岩岩相学及岩石化学特征进行了详细研究．指出本区火山岩系的主体部分属于碱性玄武岩－粗安岩－粗面岩岩石组合的碱性玄武岩系列．它与中国东部中生代环太平洋火山岩带的岩石组合及构造环境相似，它是其火山岩带的组成部分，位于兴安岭－燕山火山岩带的东南端．
In this paper the petrographic and petrochemical characteristics of the volcanic rock in Liujiang Volcano-Tectonic Basin are studied in detail. It is shown that the main body of the volcanic rock series in this area belongs to alkali -basaltic series of alkali basalt-trachy andesite-trachyte association. In volcanic rock association and tectonic setting. it is similar to the volcanic zone of Mesozoic Ere in the ease of China around Pacific Ocean, It is part of the zone and located in the southeast end of Xinganling - Yanshan volcanic belt
