“…Channel-fill deposits (F1, F2, F3) alternate with sand-rich unconfined sheet-flood deposits (F4, F5), which is characteristic for medial to distal alluvial fans (Ori 1982;Blair & McPherson 2009;Waters et al 2010). Such fans have been described from the Mediterranean and North America (Ori 1982;Nemec & Postma 1993;Waters et al 2010).

“…Sheet-floods are major components of alluvial fans with low slopes and originate as unconfined sheets of shallow water formed by the rapid but infrequent drainage of a high volume of water from the catchment area (North & Davidson 2012). A lack of vegetation promotes the flooding (Sweeney & Loope 2001;Waters et al 2010). A lack of vegetation promotes the flooding (Sweeney & Loope 2001;Waters et al 2010).…”

J. 2014 (January): Climate control on the evolution of Late Pleistocene alluvial-fan and aeolian sand-sheet systems in NW Germany.The Late Pleistocene was characterized by rapid climate oscillations with alternation of warm and cold periods that lasted up to several thousand years. Although much work has been carried out on the palaeoclimate reconstruction, a direct correlation of ice-core, marine and terrestrial records is still difficult. Here we present new data from late Middle Pleniglacial to Lateglacial alluvial-fan and aeolian sand-sheet deposits in northwestern Germany. Records of Late Pleniglacial alluvial fans in central Europe are very rare, and OSL dating is used to determine the timing of fan aggradation. In contrast to fluvial systems that commonly show a delay between climate change and incision/aggradation, the small alluvial-fan systems of the Senne area responded rapidly to climatic changes and therefore act as important terrestrial climate archives for this time span. The onset of alluvial-fan deposition correlates with the climate change from warm to cold at the end of MIS 3 (29.3Ϯ3.2 ka). Strong fan progradation started at 24.4Ϯ2.8 ka and may be related to a period of higher humidity. The vertical stacking pattern of sedimentary facies and channel styles indicate a subsequrent overall decrease in water and sediment supply, with less sustained discharges and more sporadic runoffs from the catchment area, corresponding to an increasing aridity in central Europe during the Late Pleniglacial. Major phases of channel incision and fan aggradation may have been controlled by millennial-scale Dansgaard-Oeschger cycles. The incision of channel systems is attributed to unstable climate phases at cold-warm (dry-wet) or warm-cold (wet-dry) transitions. The alluvial-fan deposits are bounded by an erosion surface and are overlain by aeolian sand-sheets that were periodically affected by flash-floods. This unconformity might be correlated with the Beuningen Gravel Bed, which is an important marker horizon in deposits of the Late Pleniglacial resulting from deflation under polar desert conditions. The deposition of aeolian sand-sheet systems (19.6Ϯ2.1 to 13.1Ϯ1.5 ka) indicates a rapid increase in aridity at the end of the Late Pleniglacial. Intercalated flash-floods deposits and palaeosols (Finow type) point to temporarily wet conditions during the Lateglacial. The formation of an ephemeral channel network probably marks the warm-cold transition from the Allerød to the Younger Dryas.

“…The dominant controls on Plio-Pleistocene deposition were tectonic uplift, sea-level change and climatic change (Poole & Robertson 1991, 1998, 2000Schirmer 1998Schirmer , 2000Waters et al 2010). These three factors interacted in ways that are still only partially understood, mainly because of limited chronology.…”

“…The downcutting is likely to have been influenced by lowered erosional base levels during glacial periods, combined with the effects of climatic change. Influx of coarse clastic material can be explained by tectonic uplift, mediated by the effects of variable humidity (Waters et al 2010). Erosion possibly intensified during interglacial periods when the climate is likely to have been wetter (Schirmer 1998(Schirmer , 2000Poole & Robertson 2000).…”

Plio-Pleistocene sediments exposed around the ophiolitic Troodos Massif document spectacular uplift from below sea level to a maximum height of c. 2000 m. Sedimentation reflects a dominant control of focused tectonic uplift, modified by the effects of glacio-eustatic sea-level change and climatic change.Understanding the uplift and controls on deposition has been hindered by an inadequate age model. Here, we present a preliminary investigation of the polarity of remanent magnetizations recorded within the upper part of the Pliocene succession in the Pissouri and Mesaoria basins and from the Pleistocene marine terrace deposits that border the Troodos Massif. When integrated with available lithostatigraphic and biostratigraphic data, the main results are as follows. Focused uplift of the Troodos Massif began during the Late Pliocene, either between 2.14 and 1.95 Ma or immediately prior to 1.77 Ma. Shallow-marine, ophiolite-derived clastic and bioclastic sediments accumulated in both the Mesaoria and Pissouri basins, implying that the Troodos Massif was uplifted as a single tectonic entity. Non-marine, deltaic and fluvial facies prograded into both of the basins during the Pleistocene (1.77 Ma-recent). Marine terraces in SW and south Cyprus were cut and covered by littoral sediments from ,0.78 Ma, suggesting that high rates of uplift of the Troodos Massif persisted into mid-and late Pleistocene time.

“…Depositional processes, morphology, morphometry, and the development of alluvial fans are controlled by a number of factors such as tectonic activity (Whipple and Trayler, 1996;Calvache et al, 1997;Li et al, 1999;Viseras et al, 2003;Harvey , 2005Harvey , , 2012Goswami et al, 2009), climate (White et al, 1996;Pope and Wilkinson, 2005;Salcher et al, 2010;Waters et al, 2010), lithology (Lecce, 1991;Blair and McPherson, 1998), base level change (Koss et al, 1994;Harvey, 2002;Storz-Peretz et al, 2011) and the morphometric properties of catchments (Oguchi, and Ohmori, 1994;Sorriso-Valvo et al, 1998;Crosta and Frattini, 2004).…”
