The study looked at how different factors affect the shape of slopes made of a mix of rocks in the Delaware Basin. By analyzing data from thousands of well logs, the researchers found that the slopes changed over time, with some becoming steeper and others spreading out more. This shift was likely due to changes in sea levels and the presence of certain rock formations underneath. Strong currents also played a role in shaping the slopes. These variations in slope shape can impact how sediments move and accumulate in the basin, influencing the overall structure of the area.
