| 摘 要： | 东莞-惠东地区白云嶂火山盆地中侏罗-早白垩世火山岩广泛发育,在其上部新发现一套碱性火山岩,岩性主要为碱长流纹质-粗面质火山碎屑岩,根据其岩石学、矿物学、岩石化学、岩石地球化学、同位素年龄及与上下层位的接触关系,将其命名为白云嶂组。其层位位于晚侏罗-早白垩世南山村组之上、早白垩世官草湖组之下,其时代为晚侏罗-早白垩世。

| Abstract: | Middle Jurassic-Early Cretaceous volcanic rock are widely distributed in Baiyunzhang volcanic eruptive basin of Dongguan-Huidong region of eastern Guangdong,where a suite of alkalic volcanic rock in upper part,mainly composed of alkali-feld-spar rhyolitic-trachytic pyroclastic rocks was discovered.In light of petrology,mineralogy,petrochemistry,petrogeochemistry,isotopic age and contact nature,the suite is named Baiyunzhan Formation.It lies between the Late Jurassic-Early Cretaceous Nanshancun Formation and lower part of the Early Cretaceous Guancaohu Formation,belonging to Late Jurassic-Early Cretaceous in age. |

| Keywords: | Baiyunzhang volcanic eruptive basin alkalic volconic Baiyunzhang Formation Late Jurassic-Early Cretaceous |
