Recent, high quality palaeomagnetic data from the West Burma Terrane (WBT) indicates rapid northwards translation (>2000 km) of the terrane, at about the velocity of the Indian Plate, from a near equatorial position in the Late Eocene until the present. This interpretation has important implications for: 1) the controversy over the configuration of Greater India prior to collision with Eurasia, 2) Cretaceous-Cenozoic plate restorations for the eastern Tethys and India Ocean, 3) when the terrane was rift from northern Gondwana, 4) the configuration of SE Asia at the end of the Indosinian orogeny, 5) understanding the general tectonic development and processes of oblique collision zones on the margins of unequal-size colliding continents. The palaeomagnetic data suggest coupling of the WBT with NE India and subsequent encounter of the WBT with SE Asia along a transform margin during the latest Eocene or Oligocene. Due to the significant implications of the palaeomagnetic model, it is important to test the implied development of the WBT against what is known of the regional geology. This study reviews the possible tectonic reconstructions for the Andaman Sea and proposes a configuration that minimises the problems with the testable geological observations. However, it remains difficult to justify the reconstruction with respect to the following aspects: 1) transform fault zone location in the Andaman Sea, 2) Andaman-Sumatra subduction zone evolution, 3) location of the Cretaceous-Eocene eastern boundary of the WBT, and 4) weak evidence for the loss of oceanic crust between the Burma Terrane and Sibumasu during Palaeocene-Eocene convergence. Consequently, there are considerable incompatibilities between geological data and the palaeomagnetic model. Substantial work is required to determine whether these incompatibilities reflect unidentified issues with the palaeomagnetic data, or deficiencies in our geological understanding.

最近，来自西缅甸地体 (WBT) 的高质量古地磁数据表明，地体从晚始新世的近赤道位置以大约印度板块的速度快速向北平移（>2000 公里），直到现在。这种解释对以下方面具有重要意义：1) 与欧亚大陆碰撞前大印度构造的争议，2) 东特提斯和印度洋的白垩纪-新生代板块修复，3) 地块从冈瓦纳北部裂谷时，4 ) 印支造山运动结束时东南亚的构造， 5) 了解大小不等碰撞大陆边缘倾斜碰撞带的一般构造发展和过程。古地磁数据表明 WBT 与印度东北部的耦合以及随后在最晚始新世或渐新世期间沿转换边缘与东南亚相遇的 WBT。由于古地磁模型的重要意义，重要的是根据已知的区域地质来测试 WBT 的隐含发展。本研究回顾了安达曼海可能的构造重建，并提出了一种可以最大限度地减少可测试地质观测问题的配置。然而，在以下几个方面仍然难以证明重建的合理性：1）转换安达曼海断裂带位置，2）安达曼-苏门答腊俯冲带演化，3）WBT白垩纪-始新世东边界的位置，和 4) 在古新世-始新世辐合期间缅甸地块和锡布马苏之间洋壳损失的弱证据。因此，地质数据与古地磁模型之间存在相当大的不兼容性。需要大量的工作来确定这些不相容性是否反映了古地磁数据中未识别的问题，或者我们对地质认识的缺陷。
