The Transantarctic Mountains (TAM), which separate the West Antarctic rift system from the stable shield of East Antarctica, are the largest mountains developed adjacent to a rift. The cause of uplift of mountains bordering rifts is poorly understood. One notion based on observations of troughs next to many uplifted blocks is that isostatic rebound produces a coeval uplift and subsidence. The results of an over-snow seismic experiment in Antarctica do not show evidence for a trough next to the TAM but indicate the extension of rifted mantle lithosphere under the TAM. Furthermore, stretching preceded the initiation of uplift, which suggests thermal buoyancy as the cause for uplift.
横贯南极山脉（TAM）将西南极裂谷系统与东南极洲稳定的盾状地分开，是沿裂谷发育的最大山脉。毗邻裂谷的山脉隆升的原因还没有得到很好的理解。一种基于对许多抬升块体旁边的槽观察的观点认为，均衡回弹产生了同时的隆升和沉降。南极雪地地震实验的结果并没有显示出 TAM 旁边有槽的证据，但表明裂谷地幔岩石圈在 TAM 下延伸。此外，伸展发生在抬升开始之前，这表明热浮力是抬升的原因。
