Abstract

The Upper Cretaceous Qiupa Formation in Tantou Basin of the western Henan province is a set of terrestrial clastic deposits. The lithology is mainly made up of thick-bedded or massive red brown silty mudstone in which intercalated beds are instability of graded bedding or massive gravel, sandy gravel or sandstone. Abundant ichnofossils were found in the strata, including Palaeophycus tubularis, Beaconites autarcticus, Planolites ichnosp.1, Planolites ichnosp.2, Scoyenia gracilis, Skolithos ichnosp., and Rhizoliths. According to the outcrop characteristics of these ichnofossils and the sedimentary features of their surrounding rocks, the Beaconites-Scoyenia ichnoassemblage and Palaeophycus-Rhizoliths ichnoassemblage were established and their sedimentary environmental models were proposed. The Beaconites-Scoyenia ichnoassemblage which is consisted of Beaconites antarcticus, Scoyenia gracilis, Planolites ichnosp.2 and Skolithos ichnosp represents the shore and shallow lacustrine sedimentary environments. The Palaeophycus-Rhizoliths ichnoassemblage which is consisted of Palaeophycus tubularis, Planolites ichnosp.1, Beaconites antarcticus and Rhizoliths represents the lacustrine fan-delta plain to fan-delta front sedimentary environments. Based on the comprehensive analysis of the lithology, sedimentary structures, sedimentary sequences and ichnofossil assemblages of the strata, 5 types of depositional sequences are differentiated and the Qiupa Formation is explained to have formed sequentially from the alluvial fan to lacustrine fan delta and then to shore and shallow lake environments.. In addition, the evolution of sedimentary environments represented in the formation is discussed. The research results not only may enrich the ichnofossil database of terrestrial basins in China and offer new data to complete further continental ichnofacies mode, but also offer scientific evidence to explain the palaeobios survival and preserved palaeoenvironments in Tantou basins of western Henan.
