Auto-Stratigraphic Evolution Of Experimental Crater-Fill Basins: Implications For Interpreting Mars Sequence Stratigraphy And Paleoclimate, Lexie Stodden
WWU Graduate School Collection
Preserved fluvial and deltaic sedimentary deposits found within martian crater-fill basins are important evidence documenting past warmer, wetter climatic periods on Mars. The morphologic and stratigraphic patterns of these sedimentary deposits are commonly interpreted to record variably complex transgression and regression histories of crater-lake levels, driven by fluctuations in the prevailing hydroclimatic conditions. Yet this tendency for direct inversion of sedimentary characteristics to formative boundary conditions largely neglects large-scale autogenic processes operating in crater-fill basins. The goal of this research is to illustrate an idiosyncratic feature of these basin types, wherein attributes of the sediment source play an outsized role …
