- Abstract
- The Lambersart "les Conquerants" trench sequence is made of a Shelly loam topped by coarse alluviums. The whole is covered by several meters thick pleniglacial loess. The palynological and malacological data shows that this Shelly loam deposit occured during Early Glacial, in cold and moist conditions and ended in a more temperate interstadial. It settled at the valley bottom, down the Weppes Country slope. Significant erosion (attributed to the Pleniglacial) occurred on the slope and the valley bottom. It broke Early glacial soils and disturbed their archaeological and palaeontological remains. Sandy and silty beds settled in the lower part. Thereafter, this valley deposit is broken appart from the slope by a transitional aera. The latter shows narrow; deepless and mobile channels infilled by sand, gravels, and a younger Shelly loam. Afterwards, pleniglacial loess accumulations grew up the slope on the previous valley bottom formations, yet protecting them. A overall look at available data indicates the large extend of similar deposits tinder the actual slope of the Weppes Country and in the tributary valley of Seclin.
