| 摘 要： | 中国南方早震旦世火山活动强烈,晚世有所减弱,既有大陆喷发又有海底喷发。基性、中性、酸性熔岩和火山碎屑岩均有,以拉斑玄武岩、钙碱性火山岩和碱性火山岩系列为主,极少量过碱性火山岩。根据地理分布和构造部位可划分为四个火山岩带,火山喷发的构造背景为后造山裂谷。

| Abstract: | The early Sinian volcanic processes were active. But they decreased in late Sinian, and appeared as continental and sea-floor eruption. The basic, intermediate, acidic lava-and associated volcaniclastic rock are of widespread occurence, which are dominanted by tholeiite, alkali-lime and alkaline volcanic series, and some ultra-alkaline volcanic rock. The four belts of volcanic rocks are classified according to geographic distribution and tectonic position. The tectonic setting of volcanic eruption is determined as a post-orogenic rift. |
