Abstract


Similar compositional and genetic characteristics for the recently deposited sediments in some lakes and ponds of the north of the Málaga province have been observed. Nevertheless, it seems to exist some differences in their mineralogical and geochemical evolution as well as in the degree of alteration of the original sediment. The mineral alterations produced in these confined lacustrine basins, with pH higher than 8, are controlled by ionic exchange between water and sediment. According to the mineral alteration degree three stadiums of mineral evolution have been detected. In addition the mineralogical and geochemical evolution and the hydrochemical characteristic of the aqueous environment are related. The study has shown that some neoformation processes of Mgrich minerals also occur.
