Abstract: Abstract The 7-km-diameter Jeokjung–Chogye Basin in Hapcheon, southeastern Korean Peninsula, is well-known for its bowl-shaped geomorphology. Here we report the first direct evidence of impact cratering from this basin based our investigations on a 142-m-deep… read more here.

DOI: 10.1016/j.icarus.2019.113409
Abstract: Abstract Although a large number of astronomical craters are actually produced by the oblique impacts onto inclined surfaces, most of the laboratory experiments mimicking the impact cratering have been performed by the vertical impact onto… read more here.

DOI: 10.1016/j.ijimpeng.2018.09.017
Abstract: Abstract A series of experiments was conducted to investigate the effect of projectile head shape on hypervelocity impact cratering. Aluminum 5052–H112 alloy thick targets were impacted by projectiles which had different heads at velocities of… read more here.

DOI: 10.1016/j.pss.2019.104755
Abstract: Abstract Ages of geological units of planetary bodies are determined from impact crater counts on their surface. These ages are model-dependent, and several models largely used in the community assume a constant production function and… read more here.

DOI: 10.1093/mnras/stx211
Abstract: Rampino & Caldeira (2015) carry out a circular spectral analysis (CSA) of the terrestrial impact cratering record over the past 260 million years (Ma), and suggest a ~26 Ma periodicity of impact events. For some… read more here.
