N2 - This relict estuary exhibits unique lateral zonation of evaporite minerals (calcite, gypsum, halite) along its 20km length. The salinity gradient in the estuary ranges from normal marine at the mouth to approximately 330 000 ppm TDS in the innermost waters. Uses the Harvie-Weare chemical equilibrium model to characterize the saturation horizons of gypsum and halite in the estuary brines. Water composition and sedimentological data support a model of the Bocana as a barred lagoon operating in a flow evaporative mode. Limited diurnal data show significant variation in brine composition as well as thermal and density stratification.-from Authors
