Scenario for the formation of cryovolcanic features associated with craters: spectrally bluish material originates from subsurface, cryoplutonic sources released or triggered by impact. Upwelling of salt rich hydrated (bluish) material forms subsurface reservoirs. Impacts mobilize such reservoirs, producing lava-like flows ponding in the crater. Ejected salt-rich hydrated material covers the flanks of craters as flows and as fine dispersed ejected or erupted salt deposits.
