Dynamic Compressive Strength and Fragmentation in Felsic Crystalline Rocks
Rae, Auriol S. P.; Kenkmann, Thomas; Padmanabha, Vivek; Poelchau, Michael H.; Schäfer, Frank (Journal of Geophysical Research: Planets, 2020)Brittle deformation in rocks depends upon loading rate; with increasing rates, typically greater than ~102 s−1, rocks become significantly stronger and undergo increasingly severe fragmentation. Dynamic conditions required ... -
Impact Experiment on Gneiss: The Effects of Foliation on Cratering Process
Agarwal, Amar; Poelchau, Michael H.; Kenkmann, Thomas; Rae, Auriol; Ebert, Matthias (Journal of Geophysical Research: Solid Earth, 2019)Two impact experiments were carried out on blocks of Maggia gneiss to assess the influence of mechanical target anisotropies on the cratering process. The experiments were done within the framework of Multidisciplinary ... -
Morphometric Characterization of Longitudinal Striae on Martian Landslides and Impact Ejecta Blankets and Implications for the Formation Mechanism
Pietrek, Alexa; Hergarten, Stefan; Kenkmann, Thomas (Journal of Geophysical Research: Planets, 2020)Longitudinal striae are a shared characteristic of long run-out landslides and layered ejecta crater deposits. They appear to be a fundamental feature of disintegrated mass flows, but their formation and the required ... -
Ramgarh, Rajasthan, India: A 10 km diameter complex impact structure
The Ramgarh structure is a morphological landmark in southeastern Rajasthan, India. Its 200 m high and 3.5–4 km wide annular collar has provoked many hypotheses regarding its origin, including impact. Here, we document ... -
Structural record of an oblique impact: the central uplift of the Upheaval Dome impact structure, Utah, USA
Scherler, Dirk; Kenkmann, Thomas; Jahn, Andreas (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Most asteroids strike their target at an oblique angle (Pierazzo & Melosh 2000). The common criterion for identifying craters formed by an oblique impact is the pattern of the ejecta blanket. On Earth, however, ejecta ... -
The fate of sandstone during impact cratering: shock compaction, cataclastic flow, and granular fluidization
Impact of solid bodies is the most fundamental of all processes that have taken place on the terrestrial planets in our Solar system (Shoemaker 1977). On Earth, impact cratering was the dominant geologic process during the ... -
The terrestrial impact crater record: A statistical analysis of morphologies, structures, ages, lithologies, and more
Abstract The number of newly discovered and confirmed impact structures on earth is growing continuously. In this review paper, the main attributes of 198 confirmed impact structures and 10 further structures, for which ...
