摘要(Abstract)：

江西南部三百山、蔡坊、版石、岩背等火山盆地由长英质火山岩组成,岩石组合与北武夷地区的武夷群一致,可归入武夷群,并可进一步划分出双峰岭和鹅湖岭两个组。锆石SHRIMPU-Pb测年结果表明,三百山盆地粗面岩的年龄为142.0±1.0Ma,蔡坊盆地流纹岩的年龄为131.4±1.3Ma,版石盆地围东一带流纹质凝灰岩的年龄为142.5±1.3Ma、门山寨一带流纹岩的年龄为130.8±0.7Ma。根据"国际地层表",晚侏罗世与早白垩世的界线划在145.5±4.0Ma,江西南部武夷群的地质时代应归于早白垩世早期。版石盆地门山寨一带的火山岩层、三百山盆地仰天湖破火山口构造北部唐屋—中寨一带的长英质火山岩应归入武夷群。
