[eng]The state of art on alluvial fan and aeolian sediments interference is presented. Although initially they are two different environments, with different processes and resulting forms, very often their interaction produces deposits that share characteristics and features from both environments, as well as, maintain inherited elements from one to each other. In this sense, the aeolian-alluvial interference is the geomorphological expression of the coincidence, disruption and/or overlapping of aeolian and alluvial environments. Climate appears to be one of the most important controls on the role and magnitude of each environment in terms of sediment supply, precipitation, runoff or aeolian transport. In this paper we discuss many examples from the Balearic Islands and Western Mediterranean where Pleistocene coastal successions show different degrees of eolian-alluvial interferences, as well as the role of eustatic fluctuation and climate changes during the Last interglacial-glacial period as drivers of this deposition system.
