Lava and Ice Interaction on Mars: Application of Terrestrial Observations and Laboratory Simulations;

Observations of terrestrial examples of lava and ice interaction have been combined with laboratory simulations to provide a framework for investigating lava and ice interaction on Mars. Identification of largeand small-scale characteristic features will indicate whether large quantities of meltwater were trapped or whether lava flow confinement occurred. These features should also enable the distinction between interaction with glacial ice or permafrost. Relationships between lava flow morphology and eruption parameters determined by laboratory simulation can be applied to Martian deposits to estimate lava composition and effusion rate, and consequently constrain mantle processes.
