Rock glaciers and protalus landforms: Analogous forms and ice sources on Earth and Mars

Whalley, W. Brian, Azizi, Fethi·2003·Journal of Geophysical Research: Planets

Abstract

The basic features and terminology of terrestrial “rock glaciers” are reviewed together with associated forms termed “protalus lobes” and “protalus ramparts.” Two basic models of rock glacier formation and flow invoke either the creep of ice derived from permafrost or glacial/former glacial activity; a third possible mechanism invokes landslide emplacement. Observations on terrestrial rock glaciers and similar forms suggest that the ice component can be produced via ground ice or from a glacier system. Finite element modeling of simple slope systems containing (1) a continuous ice layer buried by debris and (2) a mixture of ice and rigid blocks can both show creep but with very low rates, especially at low temperatures. Possible Martian examples of rock glacier and protalus lobe features are identified from Candor Chasma by wide‐angle Mars Orbiter Camera (MOC) imagery, although the topography does not allow unambiguous interpretation. Some possible ways in which MOC and Mars Orbiter Laser Altimeter (MOLA) and other Mars orbiter data could help future interpretation of rock glaciers, related protalus landforms, and ice presence are discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
