2017 brings us a couple of new geologic planetary maps. This year European groups published the same number of geologic/geomorphic planetary maps as the USGS. We present short descriptions of them and ask you to vote for your favourite map below.
Geologic Map of Meridiani Planum, Mars
by Brian M. Hynek and Gaetano Di Achille (USA)
The Meridiani Planum area is the landing site of the Opportunity rover. Authors of this map indicate that the map is using more recent orbiter data to “place rover’s findings in a broader context”. It can help evaluate the geologic and hydrologic histories of the Meridiani region.
Bedrock and structural geologic maps of eastern Candor Sulci, western Ceti Mensa, and southeastern Ceti Mensa, Candor Chasma, Valles Marineris region of Mars
by Chris H. Okubo and Tenielle A. Gaither (USA)
Another map from Valles Marineris, which is a part of a large-scale project. On two sheets we can find elevation data maps, geologic maps, cross section, stratigraphic units and events, stereonet plots (showing poles to planes of discontinuities) and other visualizations.
Generic identification and classification of morphostructures in the Noachis-Sabaea region, southern highlands of Mars
by Trishit Ruj, Goro Komatsu, James M. Dohm, Hirdy Miyamoto & Francesco Salese (Italy)
This first morphostructural map of the Noachis-Sabaea region displays structures and forms (craters, grabens, faults, ridges) with correlation to geologic units in detail. According to the authors, the work is “the basis for making inferences about Noachian-Hesperian crustal activity, and provides information for further studies regarding the reconstruction of the evolutional history of the region.”
Geologic map of Ceres
by David A. Williams , Debra L. Buczkowski , Scott C. Mest , Jennifer E.C. Scully (USA)
This map is a global summary of the large Ceres mapping project which brought us 15 quadrangle maps. These maps are available in the Geologic Mapping of Ceres Special Issue of Icarus. The global geologic map is at a scale of 1:3 500 000, which shows that impact craters dominate the surface of this dwarf planet.
