Introduction: Flank terraces are topographically subtle, laterally extensive structures on the flanks of several large Martian volcanoes [1]. The origin of terraces has been ascribed to several mechanisms, including elastic self-loading [2], lithospheric flexure [3], gravitational spreading [4], magma chamber tumes-cence [5], and shallow slumping [6]. Here we summa-rise the results of our work ...

Knowledge about the rates of pedogenic processes is essential to understand landscape development and history. It can be attained by the quantitative investigation of soil chronosequences. In this work, the development of Chromic Luvisols in the Mediterranean is addressed. The soils investigated are located on fi ve uplifted Pleistocene marine terraces in south-western Sicily, and have develope...

A terrace for Zn (a Zn terrace) is an arrangement (a1, a2, . . . , an) of the n elements of Zn such that the sets of differences ai+1 − ai and ai − ai+1 (i = 1, 2, . . . , n−1) together contain each element of Zn\{0} exactly twice. Various general constructions are given for Zn terraces of two special types: zigzag terraces and foxtrot terraces. Some special cases already appear in the literatu...

Marine terraces are ephemeral planar landforms. While tectonic and climatic forcings responsible for the generation of existing marine terraces have operated for at least 1 Myr, terraces have been completely removed by erosion above a given altitude (and hence above a given age). Above this altitude, the landscape has forgotten that it was once terraced. We ask what controls this characteristic...
