摘要

Mercury’s quadrangle H02 ‘Victoria’ is located in the planet’s northern hemisphere and lies\udbetween latitudes 22.5° N and 65° N, and between longitudes 270° E and 360° E. This\udquadrangle covers 6.5% of the planet’s surface with a total area of almost 5 million km2. Our\ud1:3,000,000-scale geologic map of the quadrangle was produced by photo-interpretation of\udremotely sensed orbital images captured by the MESSENGER spacecraft. Geologic contacts\udwere drawn between 1:300,000 and 1:600,000 mapping scale and constitute the boundaries\udof intercrater, intermediate and smooth plains units; in addition, three morpho-stratigraphic\udclasses of craters larger than 20 km were mapped. The geologic map reveals that this area is\uddominated by Intercrater Plains encompassing some almost-coeval, probably younger,\udIntermediate Plains patches and interrupted to the north-west, north-east and east by the\udCalorian Northern Smooth Plains. This map represents the first complete geologic survey of\udthe Victoria quadrangle at this scale, and an improvement of the existing 1:5,000,000 Mariner\ud10-based map, which covers only 36% of the quadrangle.
