From: Hainan mantle plume produced late Cenozoic basaltic rocks in Thailand, Southeast Asia
Distribution of late Cenozoic (<16 Ma) intraplate volcanism in the South China Sea region, which includes Beibuwan, Leiqiong peninsula, Pearl River mouth basin, SCS basin and the Indochina block29. Late Cenozoic volcanic rocks are mainly distributed within the red circle (deshed line), and include the Leizhou peninsula, Hainan Island, Pearl River Mouth Basin, Beibu gulf, South China Sea Basin, and Indochina block (reviewed by Yan et al.29), and their approximate ages are also shown. Detailed ages for late Cenozoic basalts are given in Fig. 2.
