在横贯南极山脉的中部，暴露了大约3000米的水平层状沉积岩，年龄从泥盆纪到侏罗纪不等（Grindley, 1963; Barrett, 1969; Lindsay, 1969）（表1）。序列不整合地建立在早古生代和前寒武纪的基底复合体上。在局部，信标层序中最底端的亚历山德拉组缺失，二叠纪宝塔组的岩石直接位于下伏的基底杂岩上。在伊丽莎白女王山脉的西侧，在count山的下面（图1），宝塔组坐落在中寒武纪的沙克尔顿石灰岩上（表1）。在这个地方，沙克尔顿石灰岩的悬崖上露出了一个充满碎片的洞穴。
Abstract Approximately 3,000 m of horizontally bedded sedimentary rocks ranging in age from Devonian( ?) to Jurassic are exposed in the central Transantarctic Mountains (Grindley, 1963; Barrett, 1969; Lindsay, 1969 (Table 1). The succession rests unconformably on an early Paleozoic and Precambrian basement complex. Locally, the lowermost formation of the Beacon sequence, the Alexandra Formation, is absent and the tillites of the Permian Pagoda Formation rest directly on the underlying basement complex. On the western flank of the Queen Elizabeth Range, beneath Mount Counts (Fig. 1), the Pagoda Formation rests on the Lower to Middle Cambrian Shackleton Limestone (Table 1). At this locality a debris-filled cave is exposed in cliffs of Shackleton Limestone.
