The Sedimentary records of the Hapcheon impact crater basin in Korea over the past 1.3 Ma
Frontiers in Earth Science, 2023 The Hapcheon impact crater is the only meteorite impact crater identified on the Korean peninsula. However, the morphology of the impact crater and the nature of the meteorite collision are unknown. In this study, we analyzed the sedimentary facies using

THE NEPSKY-1 IMPACT CRATER AND ITS FILL DEPOSITS ON THE BASEMENT ROOF OF THE SIBERIAN PLATFORM
Геодинамика и тектонофизика, 2020 In the Earth studies, discoveries and investigations of impact craters buried beneath thick sediments are sporadic so far and may still remain inefficient, unless geophysical surveys of the areas of interest are initiated. Such studies can provide useful

Atmospheric effects on high-velocity impact cratering in porous sandstones [PDF]
EPJ Web of ConferencesGranular geomaterials feature varied porosity and may possess pore fluids. The interactions between grains, pores, and pore fluids affect the impact dynamics in the material such as the cratering efficiency, ejecta kinetics and crater morphology. In this

Identification of Multiscale Spatial Structure of Lunar Impact Crater: A Semivariogram Approach
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Identifying the spatial structure of lunar impact craters is necessary to increase our understanding of past geologic processes on the Moon. However, detecting multiscale spatial structures of craters in images in appropriate resolutions using optimum ...

Formation mechanism of the Lidang circular structure in the Guangxi Province
Earth and Planetary Physics, 2019 The Lidang circular structure in the center of the Guangxi Province is about 8 km in diameter. This structure appears as an abnormal shallow depression that has disturbed the rather harmonic regional joint systems.

Morphological Indicators of a Mascon Beneath Ceres's Largest Crater, Kerwan
Geophysical Research Letters, 2018 Gravity data of Ceres returned by the National Aeronautics and Space Administration's Dawn spacecraft is consistent with a lower density crust of variable thickness overlying a higher density mantle. Crustal thickness variations can affect the long‐term,

Molecular parameters of post impact cooling in the Boltysh impact structure [PDF]
, 2010 Impact events have the potential to generate a number of long-term sources of heat that can lead to the initiation of hydrothermal systems when the impact occurs on a water- or ice-rich target.

Impact crater morphology and the structure of Europa's ice shell
, 2017 We performed numerical simulations of impact crater formation on Europa to infer the thickness and structure of its ice shell. The simulations were performed using iSALE to test both the conductive ice shell over ocean and the conductive lid over warm ...
