An overview of explosive volcanism on Mars

Popis výsledku v původním jazyce

Decades of space exploration reveal that Mars has been reshaped by volcanism throughout its history. The range of observed volcanic landforms shows that effusive and explosive eruptions have occurred, albeit unevenly in time and space. Evidence for explosive volcanism - characterized as eruptions in which magma is disrupted by the expansion of gases dissolved in magma or by an interaction of magma with external volatiles - is less common than evidence for effusive activity. Nonetheless, some indications of explosive volcanism have been identified at various sites. For instance, old, rimless depressions, termed paterae, on the summits of broad topographic rises with very gentle flanks located mainly around the Hellas impact basin. Also various fields of kilometre-sized cones interpreted as scoria cones, tuff rings and tuff cones, and extensive clusters of sub-kilometre-sized pitted cones in the northern lowlands proposed to be rootless cones, are thought to be constructional features caused by accumulation of volcanic fragments. Finally layered deposits widely spread in equatorial areas (e.g., the Medusae Fossae Formation), and layered stacks of ash and a putative volcanic bomb observed by rover, point to a protracted history of explosive volcanism on Mars. Yet some of these interpretations remain the matter of scientific debate. The discovery of explosive volcanism on Mars has triggered an interest in theoretical aspects of such volcanism under gravitational and atmospheric conditions different from those on Earth. These studies indicate that explosive eruptions on Mars would behave differently from those on Earth.
