Abstract
Sandy fluvial deposits of Tertiary age are described from three sand pits in the Addit area with up to 28 metres high outcrops. The deposits form up to 20 metres thick fining-upwards successions of mainly large-scale tabular cross-sets of medium and coarse sand interpreted as fluvial bars. Individual successions are capped by thinly interbedded sands and silts and occasionally completed with a coal bed. Concave-up bounding surfaces separate the fining-upwards successions. Channel switching, breaks in active channel aggradation, rapid scour- and filling events and chute activity created bounding surfaces described as a 4-tier hierarchy. The palaeocurrents derived from trough foresets suggest that the channel course was straight rather than sinuous. The current directions were generally to the south and southwest.
Highlights
Miocene deposits consisting of interfingering marine and non-marine sands and clays are found throughout mid and southern Jylland in Denmark
The deposits described in the present study probably belong to the non-marine Middle Miocene Odderup Formation
The Odderup Formation was deposited in a fluvio-deltaic environment near S0by and Fasterholt, some 40 km west of the present study area (Rasmussen, 1961; Larsen and Friis, 1973; Friis, 1978; Koch, 1989)
Summary
This fades is interpreted as having formed by 2-dimensional dunes (Harms et al, 1982) migrating under low to intermediate flow-stage in the shallower parts of a river channel. Interpreted as formed by 2-dimensional, simple bars migrating under intermediate to high stage, stable flow conditions in deeper parts of a river channel. Interpreted as formed by the migration of 3-dimensional ripples in deeper parts of the river channel under high flow stage.
