A Global Tectonic Map of Mercury
Description
This dataset is a shapefile containing tectonic structures compiled from the global shortening structure map by Byrne et al. (2014), the map of shortening structures in Borealis Planitia from Crane and Klimczak (2019), structures within large impact structures reported in Byrne et al. (2018), and troughs in ghost craters from Klimczak et al., 2012. This data was compiled in ArcGIS 10.8 and was first reported in Klimczak et al. (2023). The shapefile contains line features outlining the surface breaks of faults associated with “contractional landforms”, “extensional landforms”, or “troughs”. Traces of anticlinal fold axes, as reported in Crane and Klimczak (2019), are not part of the compilation of line features. Map features may not perfectly align with landforms on the final release of MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) global image mosaics, as some mapping was carried out on earlier mosaic versions. Shortening structures mapped in Borealis Planitia from Byrne et al. (2014) that overlapped with those mapped in Crane and Klimczak 2019 were removed. The details of the mapping and mapping criteria are reported in the individual publications. References: Byrne, P. K., Klimczak, C., Şengör, A. M. C., Solomon, S. C., Watters, T. R., and Hauck II, S.
