【摘要】 海南省乐东县丘糖岭一带出露一套河流相的粗碎屑岩,通过对其岩石组合特征、沉积环境、古生物面貌等方面进一步深入研究,认为该套地层与海南岛长昌盆地瓦窑组和长坡盆地长坡组差异明显,新建丘糖岭组,时代为渐新世-中新世。丘糖岭组的建立进一步完善了海南岛新生代岩石地层序列,为深入研究该地区晚中生代构造岩浆作用背景及早新生代的盆地演化史提供了新的资料。更多还原

【Abstract】 Based on the study of rock assemblage characteristics,sedimentary environment,palaeophyte features etc.of fluvial facies coarse clastic rocks in Ledong County,Hainan Province,a new lithostratigraphic unit,Qiutangling Formation is founded,which is different from Wayao Formation of Changchang Basin and Changpo Formation of Changpo Basin in Hainan Island.The establishing of Qiutangling Formation of Oligocene-Miocene has improved the Cenozoic lithostratigraphic unit of Hainan Island and supplied new data for tectonic-magmatism evolution in Late Mesozoic and basin development history in Early Cenozoic in Hainan island.更多还原
