• Resumen

  • The texture of the Es Codolar gravel beach, South of Ibiza, was analyzed from samples in four sections of the beach. In each section two samples have been taken: one from the upper berm and another from the lower one. A total of 400 pebbles and cobbles were measured. The distribution of shingles, their grain size and sorting have been analyzed. Shingle shape has been parameterized trough the Zingg diagram, the Wadell roundness index, the maximum projection of sphericity and the Oblate-Prolate Index. The results show a clear gradient both in grain size, roundness and the shingles sphericity from Southeast to Northwest. This clearly indicates that the source of sediment supply are located at Cap Falcó detachments, Transport is produced by long shore drift towards the Northwest and he result is the formation of a shingle barrier that closes a wetland that nowadays currently occupy by the Salinas of Ibiza.
