In this paper, given a composite integer n, we propose a method of constructing quaternary low correlation zone(LCZ) sequences of period 2n− 1 from binary m-sequences of the same length. The correlation distribution of these new quaternary LCZ sequences is derived.

Although such soils are widespread in central Iran region, adequate investigations of them are yet to be carried out. Micromorphology is one of the most important tools in plaeoclimatological studies. This investigation was carried out to study microscopic features of two paleosols from Isfahan province to recon...

There is significant debate over the rates and types of fluvial activity at the Plio-Pleistocene boundary in the hyperarid Atacama Desert of Chile. To quantify fluvial processes and help resolve this debate, we measure terrestrial cosmogenic nuclide (TCN) (Be and Ne) concentration depth profiles in three settings representing a chronosequence: (1) a late Pliocene alluvial fan representative of ...
