Mud volcanoes on Mars

A paper was recently published in Nature Geoscience about how water-laden sediment flows from mud volcanoes that might have erupted in frigid conditions on Mars would morphologically resemble basaltic pahoehoe lava flows on Earth. This result (obtained from laboratory studies) helps to explain some features observed on the norther lowlands of Mars. The authors don't cite it, but I had a paper published in 2005 that described how pitted cones in the Acidalia Planitia region were most likely mud volcanoes.
