• In this research, I explored the geology of igneous intrusive domes in the Moon and Mars. These structures have not been widely investigated outside Earth, mainly due to the difficulty in locating them. I decided to do a detailed analysis of two systems: the Valentine Domes on the Moon, and the Utopia Planitia Dome field on Mars, focusing on their properties at the surface. I followed a cartographic approach in this research, using geostratigraphic units to characterize the locations and define their geological evolution. While analyzing the Valentine Domes, I noticed the lack of an open-source tool to work with the spectral data of the Moon, this led to the creation of the MoonIndex library, a tool to process spectral cubes and generate spectral indexes for the Moon. With the aid of MoonIndex, I performed the geological analysis of the Valentine Domes. The first result was the discovery of a new dome, which was detected by using the aspect parameter. I also found that several smaller structures such as rilles, dykes, and secondary domes are associated with the main domes. The dome field in Utopia Planitia is different from the lunar location, hundreds of domes were emplaced in a large area. The study of the domes showed they originated from an intrusive-to-extrusive system, since their shapes range from cryptodomes to volcanic domes. The lunar and Martian domes show some similarities, they are basaltic, have a small incidence in the surface morphology, and their parental magmas took advantage of structural features to reach the surface. However, the genesis of the system is different. The Valentine Domes formed under a polygenetic style, while the dome field in Utopia Planitia originated in a monogenetic system. This research will open the door to discovering new intrusive systems and to better understand the ones already known.
