                         area are provided for the first time, and its sedimentary 
                         characteristics compared to those from the Cod{\'o} area to allow 
                         aleoenvironmental reconstructions. Deposits in the Graja{\'u} 
                         area include evaporites, limestones and argillites bearing 
                         features indicative of a shallow, low energy, subaqueous, saline 
                         environment exposed to meteoric and/or capillary conditions. 
                         Floodingevaporative concentration-desiccation cycles suggest a 
                         saline pan complex surrounded by extensive evaporitic mudflats. 
                         The location of the system, whether coastal or inland, is a matter 
                         open for debate. However, the later hypothesis is favored 
                         considering: 1. Sr isotopic data, with values higher than those 
                         expected for Late Aptian marine waters; 2. calcitic composition of 
                         limestones (instead of dolomitic and/or magnesitic as expected in 
                         coastal settings); and 3. presence of continental ostracods and 
                         lack of marine fauna. This interpretation is consistent with that 
                         proposed for UpperAptian deposits of the Cod{\'o} area, but the 
                         depositional system there was one dominated by more stable, 
                         well-stratified, anoxic waters and evaporite precipitation in 
                         central lacustrine areas, while in the Graja{\'u} area the salt 
                         pan was more oxygenated and ephemeral, with salt precipitation 
                         mainly in marginal areas or along surrounding mudflats.",
