(2013) assess the appar ent contradiction that the near-Earth asteroid population 14 consists of 15% binaries, while the terrestrial (and Martian) impact crater populations have only 2-4% of observable 15 doublet craters. The authors suggest that only a small fraction of sufficiently well separated binary asteroids yield 16 recognizable doublets. We generally agree with the conclusions by Miljković et al. (2013) and acknowledge the high 17 quality and relevance of the study. However, we would like to bring into focus additional geochronologic constraints 18 that are critical when evaluating terrestrial impact crater doublets. Miljković et al. (2013) appraised five potential 19 terrestrial doublets using the Earth Impact Database (EID; as of 2010). We hereby warn against the indiscriminate 20 usage of impact ages compiled in this database without an assessment based on solid isotopic and stratigraphic 21 constraints and comment on the geological, geochronological, and geochemical evidence for doublet impact craters 22 on Earth.

Terrestrial impact structures currently provide the only ground-truth data as to the role of volatiles and an atmosphere on the impact-cratering process. Recent advancements, based on studies of several well-preserved terrestrial craters, have been made regarding the role and effect of volatiles on the impact-cratering process. Combined field and laboratory studies reveal that impact melting is much more common in volatile-rich targets than previously thought, so impact-melt rocks, melt-bearing breccias, and glasses should be common on Mars.

Abstract Geological processes, including impact cratering, are fundamental throughout rocky bodies in the solar system. Studies of terrestrial impact structures, like the Ries impact structure, Germany, have informed on impact cratering processes – e.g., early hot, hydrous degassing, autometamorphism, and recrystallization/devitrification of impact glass – and products – e.g., impact melt rocks and breccias comprised of clay minerals. Yet, clay minerals of authigenic impact origin remain understudied and their formation processes poorly-understood. This thesis details the characterization of impact-generated clay minerals at Ries, showing that compositionally diverse, abundant Al/Fe/Mg smectite clays formed through these processes in thin melt-bearing breccia deposits of the ejecta, as well as at depth.

  • Melt Glasses in Martian Meteorite Elephant Moraine 79001

E-mail: [email protected] (Received 01 December 2014; revision accepted 09 December 2015) Abstract–Martian meteorite Elephant Moraine A79001 (EET 79001) has received considerable attention for the unusual composition of its shock melt glass, particularly its enrichment in sulfur relative to the host shergottite. It has been hypothesized that Martian regolith was incorporated into the melt or, conversely, that the S-enrichment stems from preferential melting of sulfide minerals in the host rock during shock. We present results from an electron microprobe study of EET 79001 including robust measurements of major and trace elements in the shock melt glass (S, Cl, Ni, Co, V, and Sc) and minerals in the host rock (Ni, Co, and V). We find that both S and major element abundances can be reconciled with previous hypotheses of regolith incorporation and/or excess sulfide melt. However, trace element characteristics of the shock melt glass, particularly Ni and Cl abundances relative to S, cannot be explained either by the incorporation of regolith or sulfide minerals. We therefore propose an alternative hypothesis whereby, prior to shock melting, portions of EET 79001 experienced acid-sulfate leaching of the mesostasis, possibly groundmass feldspar, and olivine, producing Al-sulfates that were later incorporated into the shock melt, which then quenched to glass.
