从70年代初期开始,苏联等国对南极进行了研究,结果在南极海的陆架上和大陆冰盖之下圈出了许多巨大的(达1百万千米~2或更大)沉积盆地,他们处于不同的构造位置并相当厚(2—10千米或更大)的未错动的盖层。在许多情况下还获得了有关盖层内部构造的资料。
Since the early 1970s, the Soviet Union and other countries conducted a study on the Antarctic. As a result, many giant sedimentary basins (1 million km 2 or more) were circled on the Antarctic Sea shelf and the continental ice sheet. They are in a different tectonic setting and are quite thick (2-10 km or more) with undisturbed cover. In many cases there is also information on the internal structure of the caprock.
