Techniques for analysing Late Cenozoic river terrace sequences
Stokes, Martin; Cunha, Pedro Proença; Martins, António AntunesThis special edition presents a thematic set of eight papers examining field survey, remote sensing, and dating techniques used to analyse and interpret river terrace sequences. Most river systems from around the world have terrace landforms preserved at different altitudes along their valley sides. These landform sequences commonly span the Late Cenozoic encompassing hundreds of thousands to millions of years,...
K-feldspar IRSL dating of a Pleistocene river terrace staircase sequence of the...
Martins, António; Cunha, Pedro; Buylaert, Jan Pieter; Huot, Sébastien; Murray, Andrew; Dinis, Pedro; Stokes, MartinWe present the results of K-feldspar IRSL dating of the four lower terraces (T3–T6) of the Portuguese Tejo River, in the Arripiado-Chamusca area. Terrace correlation was based upon: a) analysis of aerial photographs, geomorphological mapping and field topographic survey; b) sedimentology of the deposits; and c) luminescence dating. Sediment sampled for luminescence dating gave unusually high dose rates, of betw...
