摘　　要：对海南岛乐东盆地白垩系进行了深入研究 ,将原报万组上部一套冲积相划分出来 ,新建长茅组 ;厘订后的报万组限定在长茅组之下 ,为一套河湖相沉积 ,二者为整合接触 ,含孢粉化石 ,时代为早白垩世最晚期到晚白垩世。The Cretaceous of the Ledong Basin on the Hainan Island is intensively studied. The alluvial facies of rocks in the upper part of the original Baowan Formation are separated and named Changmao Formation. The present Baowan Formation is defined below the Changmao Formation and consists of fluviolacustrine deposits. The Changmao Formetion is conformable with the present Ledong Formation and contains fossil spores and pollen grains. Its age ranges from latest Early to Late Cretaceous.
