<p>The exploration of Mars and its geologic history has captivated scientists and the public alike. Terrestrial analogues Earth locations with geological features resembling Martian terrains are critical for bridging Earth-based research with planetary exploration. The Kachchh basin in northwestern India, particularly the Matanomadh Formation, is a noteworthy analogue site. This late Paleocene formation exhibits sedimentary structures like cross-stratified sandstone, clay pockets, and weathered lateritic profiles, resembling Martian landscapes such as Mawrth Vallis and Meridiani Planum. Key minerals, including jarosite and hydrous sulfates, identified through XRD and other geochemical techniques such as SEM–EDS, further enhance its relevance due to their association with ancient aqueous activity on Mars. Fieldwork and remote sensing reveal depositional features indicative of dynamic fluvial processes, akin to ancient Martian riverbeds. Jarosite’s presence suggests acidic, oxidizing conditions, mirroring Mars’ Noachian to Hesperian transition. The study also highlights connections to Earth’s Paleocene-Eocene Thermal Maximum, offering insights into both planetary and terrestrial climate history. Recognizing the Matanomadh Formation as a Geoheritage site would ensure its preservation, promote scientific research, and foster sustainable geotourism. Its study not only advances Mars exploration but also deepens our understanding of Earth’s geologic past, emphasizing the interconnectedness of planetary processes.</p>
