Syria Planum was previously recognized as a center for the tectonic activity of Tharsis, but not as a major locus for volcanic activity, despite its centrality over the bulge. Using high\u2010resolution images from the high resolution stereo camera on Mars Express combined with Mars Observer Laser Altimeter data, we have characterized a volcanic system that reveals a number of very interesting aspects of Mars volcanism. We identified a swarm of tens of coalesced shallow volcanic edifices, typically 10\u201330 km diameter, 0.1\u20130.2 km high, and with slopes around 0.5\u00b0. These characteristics are similar to those of small shield volcanoes found in Iceland. In addition, an intermediate\u2010sized volcano, which is the source of lava flows that extend over &gt;200 km, is observed west of this shield swarm. Our study characterizes a previously unrecognized volcanic assemblage on Mars which appears to be much more developed than was documented before, in terms of morphology, inferred origin, and periodicity of eruption. The estimated lava flux of the Syria Planum volcanoes is of the same order as the lava flux of Tharsis Montes. These characteristics suggest that Syria Planum experienced a very specific style of volcanism, which we dated to the Hesperian period.<\/jats:p>","DOI":"10.1029\/2007je002945","type":"journal-article","created":{"date-parts":[[2008,9,25]],"date-time":"2008-09-25T20:00:49Z","timestamp":1222372849000},"source":"Crossref","is-referenced-by-count":29,"title":["A swarm of small shield volcanoes on Syria Planum, Mars"],"prefix":"10.1029","volume":"113","author":[{"given":"Ana Rita","family":"Baptista","sequence":"first","affiliation":[{"name":"G\u00e9ophysique Spatiale et Plan\u00e9taire Institut de Physique du Globe de Paris Saint Maur des Foss\u00e9s France"},{"name":"IDES Universit\u00e9 Paris XI Orsay France"}]},{"given":"Nicolas","family":"Mangold","sequence":"additional","affiliation":[{"name":"IDES Universit\u00e9 Paris XI Orsay France"}]},{"given":"V\u00e9ronique","family":"Ansan","sequence":"additional","affiliation":[{"name":"IDES Universit\u00e9 Paris XI Orsay France"}]},{"given":"David","family":"Baratoux","sequence":"additional","affiliation":[{"name":"Laboratoire Dynamique Terrestre et Plan\u00e9taire, UMR5562 Observatoire Midi\u2010Pyr\u00e9n\u00e9es Universit\u00e9 de Toulouse III Toulouse France"}]},{"given":"Philippe","family":"Lognonn\u00e9","sequence":"additional","affiliation":[{"name":"G\u00e9ophysique Spatiale et Plan\u00e9taire Institut de Physique du Globe de Paris Saint Maur des Foss\u00e9s France"}]},{"given":"Eduardo I.","family":"Alves","sequence":"additional","affiliation":[{"name":"Centro de Geof\u00edsica da Universidade de Coimbra Coimbra Portugal"}]},{"given":"David A.","family":"Williams","sequence":"additional","affiliation":[{"name":"School of Earth and Space Exploration Arizona State University Tempe Arizona USA"}]},{"given":"Jacob E.","family":"Bleacher","sequence":"additional","affiliation":[{"name":"Planetary Geodynamics Laboratory NASA Goddard Space Flight Center Greenbelt Maryland USA"}]},{"given":"Philippe","family":"Masson","sequence":"additional","affiliation":[{"name":"IDES Universit\u00e9 Paris XI Orsay France"}]},{"given":"Gerhard","family":"Neukum","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Geologische Wissenschaften Freie Universit\u00e4t Berlin Berlin Germany"}]}],"member":"13","published-online":{"date-parts":[[2008,9,26]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1029\/2000JE001278"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.icarus.2004.04.018"},{"key":"e_1_2_12_4_1","first-page":"3561","article-title":"Shield volcanism and lithospheric structure beneath the Tharsis plateau, Mars","volume":"7","author":"Blasius K.
