Resumo

Beach sediments of the area under study have the following textural characteristics: 59% correspond to fine sands; in lower proportion we can find medium and coarse sands; 40% are gravel and sandy gravel; 1% include the politic fraction. Log-probabilistic curves show a general normal behavior in textural distribution. The predominant sorting is moderate indicating an intermediate maturity degree. Mineralogical characteristics are: minerals present belong to the “pampeano-patagónica” association; high concentrations of glass and garnet have been observed in some areas and this can be attributed to local dynamic conditions; using the grouping statistical analysis three groups were established and their characteristics would indicate a distributive tendency related to energy conditions of each environment; the gulfs dynamical behavior would depends on the coastal topography and on wind influences over littoral drift.
