Trough-mouth fans (TMFs; e.g. Vorren et al. 1989) are seaward-convex sedimentary depocentres composed of alternating prograding and aggrading sequences derived primarily from the accumulation of glacigenic debris-flows. In addition, sedimentation may come from contour currents, settling from subglacial meltwater plumes (Taylor et al. 2002) and repeated events of sediment mass transport (Hjelstuen et al. 2007). Ice streams hosted in the glacial troughs are the main mechanism of glacial sediment erosion and transport to the shelf edge during lowstands of sea level at glacial maxima. Glacigenic debris-flow deposition is focused at the front of glacial troughs (e.g. Laberg & Vorren 1995, 1996).

Abstract
Trough-mouth fans (TMFs; e.g. Vorren et al. 1989) are seaward-convex sedimentary depocentres composed of alternating prograding and aggrading sequences derived primarily from the accumulation of glacigenic debris-flows. In addition, sedimentation may come from contour currents, settling from subglacial meltwater plumes (Taylor et al. 2002) and repeated events of sediment mass transport (Hjelstuen et al. 2007). Ice streams hosted in the glacial troughs are the main mechanism of glacial sediment erosion and transport to the shelf edge during lowstands of sea level at glacial maxima. Glacigenic debris-flow deposition is focused at the front of glacial troughs (e.g. Laberg & Vorren 1995, 1996).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
