Abstract
Arabia Terra is classically dominated by heavily cratered terrain, and some peculiar landforms can be found mostly in craters interior. High resolution images acquired by HiRISE and CTX cameras of the Mars Reconnaissance Orbiter mission provided a wide dataset where pitted cones, mounds and knobs can be easily recognized. Those mounds are interpreted to have worked as pathways for subsurface fluid flow and escape.The distribution of cones mounds and orifices could be directly linked to the fracture network connecting their deep fluid source to the surface. In this work we present the fractal analysis of the spatial distribution of mud volcanoes and/or spring deposits source vents in the bottom of Arabia terra craters, aiming to find the depth of their fluid source.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
