Constraining Martian Sedimentation Via Analysis Of Stratal Packaging, Intracrater Layered Deposits, Arabia Terra, Mars, Sarah Beth Cadieux
Masters Theses
Craters within Arabia Terra, Mars, contain hundreds of meters of layered strata
showing systematic alternation between slope- and cliff-forming units, suggesting either
rhythmic deposition of distinct lithologies or lithologies that experienced differential
cementation. Hypothesized origins of these intercrater layered deposits include
lacustrine, aeolian, volcanic airfall, and impact surge deposition. On Earth, rhythmically
deposited strata can be examined in terms of stratal packaging, wherein the interplay of
tectonics, sediment deposition, and change in base level results in predictable patterns
with respect to changes in the amount of space available for sediment accumulation.
Fundamental differences between tectonic regimes of Earth and Mars …
