Regelation geography
WebApr 4, 2024 · 1. Regelation. This process involves entrainment of debris at the bed by a combination of pressure melting and refreezing (regelation), to create a basal debris layer (Figure 7.7). It occurs under both temperate and polythermal glaciers. The matrix of this material is commonly fine-grained, comprising clay or silt. Webregelation — /ree jeuh lay sheuhn/, n. Physics. a phenomenon in which the freezing point of water is lowered by the application of pressure; the melting and refreezing of ice, at constant temperature, caused by varying the pressure.

WebAs the pressure melting continues, the the rock slips further inside the ice. Above the rock, where there is no longer pressure being exerted, the melt water begins to refreeze, encompassing the rock entirely in ice. This process of ice melting of ice due to pressure and then refreezing is called regelation.
