只有在横贯南极山脉中部的惊奇角(Cape Surprise),才有暴露的地层学证据表明沿着山脉前缘的主要偏移,这标志着南极洲的一个主要边界。在内陆地区的泥盆纪至三叠纪冈瓦纳地层中发现了几个平行于山脉前缘的断层。根据实地观察和美国地质调查局(USGS)航空照片,结合USGS地形图和卫星高程测量,对地层进行分析,发现一系列方向和位移不同的断层。断层偏移范围估计高达850米。没有额外的范围平行断层已被确定,并没有明显的断层模式是在腹地的正面悬崖。断层可能来自白垩纪的缓慢隆起,也可能来自新生代的快速隆起。只有少数断裂在腹地可以与源头断裂系统结盟。新生代的隆升和剥蚀伴随着南极洲的冰川作用,这是由天狼星群地层记录。这些沉积物,早于今天的极地景观,比中新世中期更古老,部分可能来自渐新世早期温暖的冰川作用的最早阶段。
Only at Cape Surprise, central Transantarctic Mountains, is there exposed stratigraphic evidence for major offset along the range front, which marks a major boundary in Antarctica. Several faults parallel to the range front have been identified in the Devonian to Triassic Gondwana strata in the hinterland. Analysis of the stratigraphy based on field observations and the United States Geological Survey (USGS) aerial photographs, in conjunction with USGS topographic sheets and satellite-derived elevation measurements, suggests an array of faults with varying orientations and displacements. Fault offsets range up to an estimated 850 metres. No additional range-parallel faults have been identified and no clear pattern of faulting is evident in the hinterland of the frontal escarpment. Faulting may date from the time of slow uplift during the Cretaceous as well as the more rapid Cenozoic uplift of the range. Only a few faults in the hinterland can be allied with the fontal fault system. Cenozoic uplift and associated denudation was accompanied by glaciation of Antarctica, which is documented by Sirius Group strata. These deposits, which pre-date today’s polar landscape, are older than mid Miocene, and in part may date from the earliest stages of warm-based glaciation in the early Oligocene.
