A stream-flow controlled "wet" Late Quaternary alluvial fan, NW Peloponnese, Greece
Main Article Content
Abstract
The Selemnos Fan is one of a series of similar Holocene alluvial fans between Panahaikon Mountain and the Gulf of Patras, developed in a wet Mediterranean climate. Three major lithofacies are distinguished: conglomerate, pebbly mudstone and sandy silt to mud. Sheet-like conglomerates may form in a manner analogous to crevasse splays. Channel-filling conglomerates are deposited on longitudinal bars. Pebbly mudstone is deposited from debris flows. The mud and silty sand are an overbank facies. Channel-filling conglomerate is the dominant facies, particularly in proximal parts of the fan. The Selemnos Fan differs from previously described "wet" alluvial fans, particularly in the absence of sandy facies. Similar fans of Pliocene-Quaternary age are common in Greece and may be characteristic of areas of Mediterranean climate.
