SIMULATING SPATIAL AND TEMPORAL PATTERNS OF ARCHITECTURE AND FOSSIL PRESERVATION ACROSS NONMARINE EXTENSIONAL BASINS (Invited Presentation)
Trends in architecture, species diversity, and elevation in relation to accommodation emerge across the basin simulations. Footwall architecture is overall HAST-like, whereas hangingwall architecture is LAST-like updip, becoming increasingly HAST-like downdip. Species diversity and occurrences also decrease downdip (with decreasing accommodation) on the footwall and increase downdip (with increasing accommodation) on the hangingwall. Overall diversity of the footwall is nearly twice as high as hangingwall diversity, and footwall occurrences are four times greater than hangingwall occurrences. Accommodation and sedimentation are linked to elevation trends in basin simulations, which likely contribute to spatial differences in diversity. On the footwall, elevation represented in stratigraphic columns tends to decrease with time, whereas on the hangingwall, elevation increases with time. The total span of elevations preserved in footwall records is greater than the hangingwall and may contribute to higher species diversity on the footwall.
