摘要：
A late Holocene depositional surface has been identified in the lower Narmada basin of western India. This terraced surface occupies the valley formed by the incision of the mid-late Holocene surface. Radiocarbon dating of organic-rich clay horizons indicates that these terrace sediments were deposited between 1900 and 1200 yrs BP, well corresponding with the large-magnitude palaeoflood records of the central Narmada basin. These terraces occur as 2-4 m high uplifted surfaces and point to a latest phase of tectonic uplift in the lower Narmada during the historical times.
