So far, however, the marked lack of dated sediments between ~70 and 25 ka in
our data may be interpreted as the result from discrete periods of
erosion along the playa margin (e.g. deflation), changes in the
spatial patterns in sediment delivery between the successive lake
stands, or the laterally active nature of avulsive deltaic systems not
captured by the limited extent of our stratigraphic transects.
Additional sedimentary cores are needed to clarify this issue.
