摘　　要：赣南—粤北地区鸡笼嶂组是一套以酸性火山岩为主的岩石组合 ,属晚侏罗世莲花寨群。本文在讨论了鸡笼嶂组火山岩的岩石学、岩石化学特征基础上 。The Jilongzhang Formation in the South Jiangxi-North Guangdong area is a suite of volcanic rocks dominated by acid composition,Which can be attributed to the Late Jurassic Lianhuazhai Group.Based on the petrological and petrochemical features of this rock suite,this paper deals preliminarily with the possible tectonic environment and genetic mechanism of the volcanic rocks in question.
