Harms (1974) model of density
"overflow" sedimentation of laminated terrigenous sediment
in the Delaware basin. Low-density sand-bearing flows were unable to displace dense, saline,
basin-center brines and thus moved across the upper interface of the brines dropping their
sediment load as they lost velocity. Rarer, denser currents displaced basinal brines
yielding classic traction deposits. Process could have operated during both
relative high- and low-stands of sea level.
