A GIS environment was used to integrate the geological map of Mercury, with new reflectance data obtained after the third FlyBy of MESSENGER spacecraft and the Crater Catalog recently published (2). The aim was to enlarge as much as possible the data coverage and integrate the outcropping geology data with crater distribution in order to evaluate relationships between geomorphological features and impact craters. New intriguing features have been observed across the innermost Planet, mainly considering the volcanic activity which in some locations is particularly related with impact craters. An example is given by the area south of Rachmaninoff Basin (RB), encompassed between 1° - 40° N and 55° - 80° E. In this region we mapped a 1500 km long and 550 km wide smooth plain with high reflectance terrains outcropping and low crater density which is interpreted as a very recent massif volcanic flow. This volcanic event is very similar to those which filled the RB (3) and it probably originated from one or more craters filled by the volcanic deposits itself. Another similar deposit is observed NE respect to the RB, in close relationship with a marked bright area interpreted as a volcanic pyroclastic deposits (3). The last deposit with smooth morphology and low crater density in this area is the infill of the crater about 550 km NE of RB. In all these cases, outcropping deposits are interpreted as very recent (< 1 Gy) volcanic products originated after a marked craterization which deeply influenced the crustal behavior across the entire Rachmaninoff region. Another constraint to this hypothesis is given by the fact that all mapped volcanic deposits are regularly affected by several linear features (red lines in figure) suggesting a close relationship between volcanic activity and tectonic deformation which generally postdate the volcanic event.
