Some models assume formation of gullies by liquid water but they cannot explain the absence of the features in the equator regions. Other models assume CO2 as a volatile associated with the formation of gullies. It is shown that a latitude of the boundary between regions with CO2 consolidation on poleward-facing slops and those without CO2 condensation is about a latitude of 30 deg. The result suggests a possibility of some correlation between the existence of CO2 and the formation of gullies., 資料番号: AA0046650018}, pages = {69--72}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Temperature constraint on formation mechanism of recent gullies on Mars}, year = {2003} }
