Theauthors acknowledge the use of MESSENGER data pro-cessed by NASA/Johns Hopkins University Applied PhysicsLaboratory/Carnegie Institution of Washington.Tolstoj quadrangle (H08) is located in the equatorial area of Mercury, between 22.5°N and 22.5°S and 144° and 216°E. Using the NASA/MESSENGER data, we compiled a geological map of thequadrangle at a scale of 1:3.000.000. The main basemap we used was the MDIS 166 m/pixelBDR mosaic. In addition, mosaics with high-incidence illumination from west and east, MDISglobal color mosaics, and the MDIS global DEM have been taken into account. In the map,we considered three feature classes: geological units, lineaments, and surface features.Geological units consist of crater material and plains. Lineaments include crater and pit rims,and structures. Finally, surface features are subdivided into crater chains or clusters, hollows,faculae, bright and dark material. The geological map will be integrated into the global 1:3Mgeological map of Mercury, which is being prepared in support to the ESA/JAXABepiColombo mission.STAMPAenArticlehttps://doi.org/10.1080/17445647.2024.24216002-s2.0-85209593230https://api.elsevier.com/content/abstract/scopus_id/85209593230https://www.tandfonline.com/doi/full/10.1080/17445647.2024.2421600FIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_15 Space sciences
