Marine evaporites are being deposited in the Ojo de Liebre Lagoon area, Baja California, in shallow diked basins flooded by high tides from an adjacent lagoon. Aragonite is deposited in the brine pans where daytime pH is high because of photosynthesis. Halite is deposited when wind transports brine into inner basins, and most of the gypsum is intermediate in location. Evaporites and brine support a very large standing stock of organisms.
