东南亚的重建已被尝试将巽他板块和菲律宾海板块视为50 Ma至15 Ma之间的（相对）刚性块体。罗伯特·霍尔（Robert Hall）出版的重建（1996年版）已被使用，但根据地质感知和偏见从婆罗洲向西修改，收集了36年的研究该地区。巽他和菲律宾海被视为没有经历破坏性内部变形的刚性块体。就巽他而言，这意味着第三纪裂谷盆地已经形成，但除了西部的安达曼海和东部的南中国海之外，没有形成洋壳。在这种解释中，印度支那在35 Ma到15 Ma之间被挤出了大约700公里（地图以5 Ma的间隔显示，在霍尔之后）。沿着苏门答腊断层的右向运动！安达曼/实皆市系统与沿红河断层及其前身西巴拉姆线的左行运动沿着。菲律宾海板块已经移动了很长的距离，相对于巽他岛整体上有一个左行位移。巽他和菲律宾海板块之间较小的块体，控制较少，内部变形强烈，在这种重建中以适应主要块体运动的方式进行了处理。
A reconstruction of Southeast Asia has been attempted which treats the Sunda block and the Philippine Sea Plate as (relatively) rigid blocks between 50 Ma and 15 Ma. The published reconstructions of Robert Hall (1996 version) have been utilised but modified from Borneo westwards in accordance with geological perceptions and prejudices assembled over thirty-six years of studying the region. Sunda and the Philippine Sea are treated as rigid blocks that have not undergone disruptive internal deformation. In the case of Sunda, this means that Tertiary rift basins have formed but that there has been no oceanic crust developed except in the Andaman Sea on the west and the South China Sea on the east. In this interpretation Indochina has been extruded about 700 km between 35 Ma and 15 Ma (maps are shown at five-Ma intervals, following Hall). Right-lateral movement along the Sumatra Fault! Andaman/Sagaing system is paired with left-lateral movement along the Red River Fault and its precursor, the West Baram Line. The Philippine Sea Plate has moved great distances with an overall left-lateral displacement with respect to Sunda. Smaller blocks between Sunda and the Philippine Sea Plate with less control and with strong internal deformation have been treated in this reconstruction in a manner that accommodates the movements of the major blocks.
