根据海南岛石炭纪二叠纪的古生物、古气候、古构造、古地磁及岩性岩相资料与华南大陆及冈瓦纳大陆的对比分析,初步认为海南岛在石炭纪二叠纪时既不属于冈瓦纳大陆的残体,也不与华南大陆相连,而是远离冈瓦纳大陆,靠近华南大陆并有宽阔海域与之相隔的古特提斯海中的一个孤岛。该岛在早石炭世大致位于南纬5.1°,早二叠世约位于北纬21.87°。
According to the Carboniferous Permian paleontology, paleoclimate, palaeo-structure, palaeomagnetic and lithological facies data from the Carboniferous in Hainan Island and the comparative analysis of the South China and Gondwanaland, it is preliminarily believed that neither the Hainan Island nor the Permian during the Carboniferous Permian It belongs to the remnants of the mainland of Gondwanaland and is not connected to the mainland of South China. Instead, it is an island away from the mainland of Gondwanaland, near the mainland of South China and separated by a vast sea area. The island is located approximately 5.1 ° s in the Early Carboniferous and about 21.87 ° north latitude in the Early Permian.
