<p><strong>Introduction:</strong>&#160;</p>
</div><p>The Neruda Quadrangle (H-13), Mercury, is one of the final uncharted regions on the planet. With ESA-JAXA&#8217;s BepiColombo mission underway, it is imperative that a full set of comprehensive geological maps is produced prior to the spacecraft&#8217;s arrival, to provide context for BepiColombo&#8217;s studies. Geological mapping of H-13 has commenced as part of the PLANMAP project to map the entire planet at a scale of 1:3M [1&#8211;7].</p><p>&#160;</p><p><strong>Data and Methods:</strong>&#160;</p><p>The primary base map to be used is the 166m/pixel high-resolution monochrome global mosaic. Additionally, the 665m/pixel enhanced colour global mosaic as well as narrow-angle camera (NAC) images are used for interpretation and quality control. All data were obtained by MESSENGER&#8217;s Mercury Dual Imaging System (MDIS). ArcGIS software is used for mapping following both USGS and PLANMAP practices. The map is projected as a Lambert Conformable Conic. To enable accurate correlation with neighbouring quadrangles, a 5&#176; overlap is being mapped.</p><p><strong>&#160;</strong></p><p><strong>Mapping Units and Features:</strong>&#160;</p><p>Mercury&#8217;s geological terrains are divided into four overarching units: Crater Materials, Smooth Plains, Intermediate Plains and Intercrater Plains [8]. Crater Materials are further subdivided based on the degree of crater degradation with both three class [2] and five class classifications being mapped [8].</p><p>Structural features such as lobate scarps, wrinkle ridges and high-relief ridges are distinguished using linework.</p><p>&#160;</p><p><strong>Acknowledgements:</strong></p><p>Gratitude is given to STFC and the Open University Space Strategic Research Area that make this research possible (ST/T506321/1).
