| Sumario: | The interpretation of the vertical evolution of the sedimentary deposit from Gallocanta lake has allowed to differentiate three sedimentary stages in the general sequence evolution. The depositional system consists of alluvial fans systems related laterally to the lacustrine facies. In the first evolutionary stage it is produced a sedimentation of distal alluvial areas under arid climatic conditions. After this period, and in relation with a more humid episode (about 2000 BP) it starts the lacustrine stage. The installation of a shallow carbonated lake takes place and the lake reached its maximum of depth (4 m). Finally, from 1837 cal AD it is produced a decrease of the depth of the water in relation with a more warm and dry clime. The third stage of saline carbonated lake that happens nowadays took place. The alluvial systems reduce its activity throughout the time |
