Popis: The preliminary study of the cross-section of the Selle Valley at Conty has allowed a reconstruction of the river's development (morphology and sedimentation) in relation to climatic variation during the Lateglacial and the Early Holocene. This comprises: incision and passage to a transitional system during the Bolling; single meandering channel during the Allerod with organic overbank silt deposition, infilling by calcareous silts during the Younger Dryas; and, finally, a new major incision phase at the beginning of the Holocene followed by the lowering of the fluvial dynamic, and the infilling of the whole valley by peat.
