本文评述了横贯南极山脉中部上古生界-下中生界维多利亚群上部的地层学特征。Falla组下部火山岩贫乏部分和上部火山岩富集部分之间存在明显的岩性对比。Falla组的名称仅限于层序中火山贫乏的下部，使其成为维多利亚群中最年轻的组。上部火山岩部分为凝灰质层序，被命名为汉森组。
The stratigraphy of the upper part of the Upper Palaeozoic–Lower Mesozoic Victoria Group in the central Transantarctic Mountains is reviewed. Marked lithologic contrasts exist in the Falla Formation between the lower volcanic-poor part and the upper volcaniclastic part. The name Falla Formation is here restricted to the lower volcanic-poor part of the sequence making it the youngest formation in the Victoria Group. The upper volcaniclastic part, a tuffaceous sequence, is named the Hanson Formation.
