Riedel, Christian; Michael, Gregory. G; Orgel, Csilla; Baum, Carsten; van der Bogert, Carolyn; Hiesinger, Harry, 2021, "Replication Data for: Studying the Global Spatial Randomness of Impact Craters on Mercury, Venus, and the Moon With Geodesic Neighborhood Relationship", https://doi.org/10.35003/J0CULJ, TRR 170-DB, V1
• We improve approaches to quantify the spatial randomness of impact craters by applying geodesic methods • We apply these methods to analyze the global spatial randomness of impact crater populations on Mercury, Venus, and the Moon • We use the results to investigate known crate...

Liu, Tiantian; Michael, Gregory; Haber, Thomas; Wünnemann, Kai, 2021, "Replication Data for: Formation of Small Craters in the Lunar Regolith: How Do They Influence the Preservation of Ancient Melt at the Surface?", https://doi.org/10.35003/H1ZTZD, TRR 170-DB, V1, UNF:6:bvWWrYpnLTeKhRbNyqf9Pg== [fileUNF]
• A numerical model is developed to investigate the effect of small impact gardening on ancient melt in the lunar near-surface • Gardening of craters <100 m in diameter likely lead to the excess of datable impact melt <0.5 Ga in lunar regolith samples • Distribution of radiometri...

Liu, Tiantian; Michael, Gregory; Zhu, Menghua; Wünnemann, Kai, 2021, "Replication Data for: Predicted Sources of Samples Returned from Chang’e-5 Landing Region", https://doi.org/10.35003/IOFFGV, TRR 170-DB, V1, UNF:6:YQPdKeV3MQymDMneqCKSCw== [fileUNF]
• A numerical model is applied to trace the evolving distribution of components over the Chang’e-5 landing region. • The local mare component should account for ~60% in the samples. • The samples could contain abundant Imbrium melt.

Riedel, Christian; Minton, David A.; Michael, Gregory; Orgel, Csilla; van der Bogert, Carolin H.; Hiesinger, Harald, 2021, "Replication Data for: Degradation of Small Simple and Large Complex Lunar Craters: Not a Simple Scale Dependence", https://doi.org/10.35003/C1K4CZ, TRR 170-DB, V1
• We model the surface evolution for a pre-Nectarian lunar surface unit• Relative to their size, large craters are less destructive to the surrounding terrain than small simple craters• A simple scale dependence from small to large craters does not explain the per-crater contribu...

Mari, N.; Riches, A.J.V.; Hallis, L.J.; Marrocchi, Y.; Villeneuve, J.; Gleissner, P.; Becker, H.; Lee, M.R., 2021, "Replication Data for: Syneruptive incorporation of martian surface sulphur in the nakhlite lava flows revealed by S and Os isotopes and highly siderophile elements: implication for mantle sources in Mars.", https://doi.org/10.35003/O8GECT, TRR 170-DB, V1, UNF:6:Dmn5rtyum+xjkzfIq07ebg== [fileUNF]
The data set contains petrographic (BSE and X-ray maps), chemical (highly siderophile elements), and stable isotope (in situ ∆33S and δ34S for sulpide grains) data for five Martian meteorite samples (nakhlites). Samples were obtained from the Natural History Museum of London and...

Kneissl, T.; Michael, G.G.; Schmedemann, N., 2021, "Replication Data for: Treatment of non-sparse cratering in planetary surface dating.", https://doi.org/10.35003/J5PLYW, TRR170-DB, V1
• We present a new technique for the treatment of non-sparsely cratered surfaces. • Technique accounts for loss of small craters due to subsequent crater coverage. • Correction extends the crater diameter range usable for age extractions. • CSFDs on lunar highlands seem consisten...

Wahl, Daniel; Wieczorek, M. A.; Wünnemann, Kai; Oberst, Jürgen, 2021, "Replication Data for: Crustal Porosity of Lunar Impact Basins", https://doi.org/10.35003/NXHBEE, TRR 170-DB, V1
• The bulk density and porosity of the upper highland crust are revisited using a high-resolution GRAIL gravity field model (Park et al., 2015) in combination with LOLA topography (Smith et al., 2017) and independently estimated grain densities • Using the estimated bulk densitie...

Wahl, Daniel; Oberst, Jürgen, 2021, "Replication Data for: Lateral variation in bulk density and porosity of the upper Lunar crust from high-resolution gravity and topography data: comparison of different analysis techniques.", https://doi.org/10.35003/EJQ3E8, TRR 170-DB, V1
We map lateral variations in bulk density of the upper lunar highland crust using the most recent GRAIL gravity field solution of degree and order 1500 in combination with LOLA topography data, both truncated to an upper limit of degree and order 700. Our maps have a spatial reso...

Lui, Tiantian; Michael, Greg; Engelmann, Juliane; Wünnemann, Kai; Oberst, Jürgen, 2021, "Replication Data for: Regolith mixing by impacts: Lateral diffusion of basin melt.", https://doi.org/10.35003/SE84PG, TRR 170-DB, V1
• Cumulative impact gardening on presence of melt laterally and with depth is modeled by means of a Monte Carlo approach. • The quantitative abundance of the melt from three mid- to late-forming basin is estimated. • Burying and transportation play more important roles than re-me...

Orgel, Csilla; Michael, Gregory; Fassett, Caleb I.; van der Bogert, Carolyn H.; Riedel, Christian; Kneissl, Thomas; Hiesinger, Harald, 2021, "Replication Data for: Ancient Bombardment of the Inner Solar System: Reinvestigation of the "Fingerprints" of Different Impactor Populations on the Lunar Surface", https://doi.org/10.35003/8L4TZC, TRR 170-DB, V1
Craterstats (.scc, .plt and .txt) files, GIS-ready .shp files based on Head et al. (2010) and Fassett et al. (2012)" Note: We reloaded all the CSFD measurements (GIS-ready files) into new shapefiles and recalculated the area and crater sizes in an updated CraterTools extension.
