Timing of the faulting on the Wispy Terrain of Dione based on stratigraphic relationships with impact craters [PDF]
JGR Planets, Volume121, Issue11, November 2016, Pages 2325-2334, 2022 The trailing hemisphere of Dione is characterized by the Wispy Terrain, where it exhibits a hemispheric-scale network of extensional tectonic faults superposed on the moon's cratered surface. The faults likely reflect past endogenic activity and Dione's interior thermal history.

Model Age Derivation of Large Martian Impact Craters, Using Automatic Crater Counting Methods
Earth and Space Science, 2021 Determining when an impact crater formed is a complex and tedious task. However, this knowledge is crucial to understanding the geological history of planetary bodies and, more specifically, gives information on erosion rate measurements, meteorite ...

Crater production on Titan and surface chronology [PDF]
A&A 660, A127 (2022), 2022 Impact crater counts on the Saturnian satellites are a key element for estimating their surface ages and placing constraints on their impactor population. The Cassini mission radar observations allowed crater counts to be made on the surface of Titan, revealing an unexpected scarcity of impact craters that show high levels of degradation.

Impact cratering and the Oort Cloud [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 We calculate the expected flux profile of comets into the planetary system from the Oort cloud arising from Galactic tides and encounters with molecular clouds. We find that both periodic and sporadic bombardment episodes, with amplitudes an order of magnitude above background, occur on characteristic timescales ~25-35 Myr.

Evaluation of Geomorphological Evidences for Possible Impact Crater of Zirouki in Sistan and Baluchestan, SE Iran [PDF]
مخاطرات محیط طبیعی, 2014 Despite the extensive studies on geomorphological phenomena in Iran, since investigation of meteorite impact craters h not been considered. Based on both remote sensing technique and field work we have recognized the circular structure of Zirouki crater ...

Complex crater formation by oblique impacts on the Earth and Moon [PDF]
, 2022 Almost all meteorite impacts occur at oblique incidence angles, but the effect of impact angle on crater size is not well understood, especially for large craters. To improve oblique impact crater scaling, we present a suite of simulations of complex crater formation on Earth and the Moon over a range of impact angles, velocities and impactor sizes. We

Degradation of small simple and large complex lunar craters: Not a simple scale dependence [PDF]
, 2020 The crater record of a planetary surface unit is often analyzed by its cumulative size‐frequency distribution (CSFD). Measuring CSFDs involves traditional approaches, such as traditional crater counting (TCC) and buffered crater counting (BCC), as well ...

Experimental Investigation of the Crater Caused by Hypervelocity Rod Projectile Impacting on Rocks
Shock and Vibration, 2020 To investigate the cratering effects of hypervelocity rod projectile impacting on rocks, a two-stage light gas gun was used to carry out 10 groups of small-scale experiments, whose velocity ranges from 1.5 km/s to 4.1 km/s.
