维多利亚陆盆地是南极洲横贯南极山脉罗斯海边缘沿着的一个深裂谷边缘盆地。地震数据表明，这个140公里宽的盆地含有约14公里的沉积物。从盆地侧翼的钻探结果表明，这些沉积物大多是始新世晚期或更年轻的年龄。根据地震资料，通过指示几个裂谷幕的角度不整合面，确定了四个主要层序。盆地形成的约束来自使用弯曲悬臂梁模型。该模型再现了盆地形成的主要特征（形状，大小，时间和广泛的地层）适度以及使用四个裂谷情节的五个主要故障，但不匹配的地震地层学的详细几何形状。
The Victoria Land Basin is a deep rift margin basin that lies along the Ross Sea margin of the Transantarctic Mountains, Antarctica. Seismic data indicates that the 140 km wide basin contains some 14 km of sediments. Drilling results from the flank of the basin suggests that most of these sediments are late Eocene or younger in age. Four major sequences are defined on the seismic data by angular unconformities indicating several rift episodes. Constraints on the basin formation are derived using flexural cantilever models. The model reproduces the main features (shape, size, timing and broad stratigraphy) of the basin formation moderately well using four rift episodes on five main faults, but does not match the detailed geometry of the seismic stratigraphy.
