Abstract:
The morphology of `spiders' appears to be controlled by bedding and local jointing of the rocks; implying that expelled fluids are derived from within a few hundred metres of the Martian surface. Some spider-ravines modify, some destroy and others create crust in a dynamic near-surface process that mimics subduction zones. Ancient forms of these structures have had a more extensive coverage. Some complex `spiders' may revert to ravines in the summer.
