Preliminary Results of 1:3 Million Geological Mapping of the Mercury Quadrangle H-10 (Derain)

MESSENGER heralded a new era in our geological understanding of Mercury as a dynamic planet. Geological mapping of surface features is essential in understanding both local and global geology. To this end, we have started mapping the H-10 (Derain) quadrangle to publish at 1:3 million scale to the same standards as other new MESSENGER mapping. This will allow integration into a global geological map. H-10 quadrangle is in the equatorial band of Mercury, located between 0°–72°E and 22N°–22°S. It was not imaged by Mariner 10; therefore this MESSENGER-based work is the first high resolution geological mapping of the quadrangle. Here we present initial observations from the first stages of mapping
