Description:
Mars was most active during its first billion years. The core, mantle, and crust formed within approximately 50 million years of solar system formation. A magnetic dynamo in a convecting fluid core magnetized the crust, and the global field shielded a more massive early atmosphere against solar wind stripping. The Tharsis province became a focus for volcanism, deformation, and outgassing of water and carbon dioxide in quantities possibly sufficient to induce episodes of climate warming. Surficial and near-surface water contributed to regionally extensive erosion, sediment transport, and chemical alteration. Deep hydrothermal circulation accelerated crustal cooling, preserved variations in crustal thickness, and modified patterns of crustal magnetization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Solomon, Sean C -- Aharonson, Oded -- Aurnou, Jonathan M -- Banerdt, W Bruce -- Carr, Michael H -- Dombard, Andrew J -- Frey, Herbert V -- Golombek, Matthew P -- Hauck, Steven A 2nd -- Head, James W 3rd -- Jakosky, Bruce M -- Johnson, Catherine L -- McGovern, Patrick J -- Neumann, Gregory A -- Phillips, Roger J -- Smith, David E -- Zuber, Maria T -- New York, N.Y. -- Science. 2005 Feb 25;307(5713):1214-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Terrestrial Magnetism, Carnegie Institution of Washington, Washington, DC 20015, USA. scs@dtm.ciw.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15731435" target="_blank"〉PubMed〈/a〉
