Re-Examination Of Changes In Fluvial Stacking Pattern Across The P-T Boundary In The Central Transantarctic Mountains, Antarctica, Danielle Sieger

Theses and Dissertations

A change in fluvial style and a change in the stacking pattern of fluvial channel sandstone bodies occur across the Buckley‒Fremouw formational contact in the central Transantarctic Mountains in Antarctica. Strata in the Buckley Formation are characterized by thick floodplain deposits in the Middle to Upper Permian Buckley Formation; whereas, stacked interconnected sandstone bodies occur in the Triassic Fremouw Formation (Barrett et al., 1986; Isbell & Macdonald, 1991a, 1991b; Collinson et al., 1994; Isbell et al., 1997; 2005). Such changes in fluvial stacking patterns have been attributed to changes in the creation of accommodation within basins due to changes in …
