✦ Synopsis

Mars concretion systems. Although the analogue is not a perfect match in every geologic parameter, the mere presence of these spherical haematite concretions implies significant pore volumes of moving subsurface fluids through porous rock.Haematite is one of the few minerals found on Mars that can be linked directly to water-related processes. Utah haematite concretions are similar to the Mars concretions with spherical morphology, haematite composition, and loose, weathered accumulations. The abundance of quartz in the Utah example could pose challenges for finding spectral matches to the concretions. However, the similarities and differences of the Utah and Mars haematite concretions should stimulate further investigations. The potential role of biomediation in the precipitation of some terrestrial haematite concretions could also hold important clues in the search for life on Mars. Intriguing factors in the Mars system yet to be explored include: spectral comparisons, the source of the iron, the driving mechanism for fluid flow, and other chemical and physical parameters. This Utah analogue presents a model for a fascinating history of fluid flow in the haematite region of Mars.
