1906 J. G. Andersson in Jrnl. Geol. (Chicago) 14 96 This process, the slow flowing from higher to lower ground of masses of waste saturated with water.., I propose to name solifluction.

1916 G. Taylor With Scott 115 These symmetrical polygons are due to a slow movement of half-frozen soil, which has been noted in polar lands, and is called solifluxion or soil-creep.

1924 J. S. Huxley & N. E. Odell in Geogr. Jrnl. 63 224 It remains to mention the chief modifications of the stone-polygons due to ‘solifluction’ (or soil-flow) and other causes.

1928 Greenland 1 437 The peculiar solifluction within the areas of the less resistant nepheline-syenites.

1936 Geogr. Jrnl. 87 449 Solifluction also is known from the Alps, as for instance in the flysch region of the Segnas Pass.

1938 C. F. S. Sharpe Landslides iii. 35 The definition given by Andersson..does not limit solifluction to cold climates. From the cases he mentions, however, and from subsequent usages by Eakin.., Nichols.., and others, the word solifluction has come to be intimately associated with frost action.

1957 G. E. Hutchinson Treat. Limnol. I. i. 144 The presence of such ponds can lead to striking solifluction if the pressure of the water on the down-slope wall is great enough.

1965 M. Fieldes et al. in G. J. Williams Econ. Geol. N.Z. xx. 364/2 This solifluxion is thought to account for the emplacement of plastic clays occurring at..localities in the Wellington area.

1974 C. Taylor Fieldwork in Medieval Archaeol. iv. 85 Deep hollows on the faces of chalk scarps in Wessex are usually the result of periglacial action and solifluction.

1954 Sci. News 33 70 On the continent, the task of dating soliflucted material is aided by interbedded sheets of loess.

1977 Antiquaries Jrnl. 57 187 Some sarsens..could be derived from chalk or Greensand as could the soliflucted spread in the Vale of Pewsey.

1924 Geogr. Jrnl. 63 225 On well-developed solifluctional slopes of mixed material, the different-sized stones move downwards at different rates.

1956 Antiquity 30 99 Weathered carboniferous sandstones (whose upper solifluxional levels are in several places separated by multi-coloured clays).

1971 J. N. Jennings in Jennings & Mabbutt Landform Studies from Australia & New Guinea xii. 271 Their hummockiness and the way they spread out distally with a bulging lower margin are features in favour of an end-moraine rather than a solifluctional origin.
