Scientific paper

It is argued that the local volcanic heat sources inevitably present in the rift zones on the flanks of large Martian volcanoes could have very significantly extended the sizes of regions within which water could persist as a liquid for time periods of at least tens and probably hundreds of millions of years, the latter intervals being long enough, by analogy with what happened on the Earth, for significant biological development. It is possible that the ultimate limitation on the lifetime of such favored regions is not so much the availablity of heat but rather the need to prevent water from leaving the regions too rapidly as a result of the imposed thermal gradient or to resupply water from deeper levels in the hydrothermal system of the volcano to compensate for that lost.
