Meteoritics &Planetary Science, EarlyView.Abstract The majority of planetary impacts occur at oblique angles. Impact structures on Earth are commonly eroded or buried, rendering the identification of the direction and angle of impact—using methods such as asymmetries in ejecta distribution, surface topographic expression, central uplift structure, and geophysical anomalies—challenging. In this

Morphology of Meteorite Surfaces Ablated by High-Power Lasers: Review and Applications
Applied Sciences, 2022 Under controlled laboratory conditions, lasers represent a source of energy with well-defined parameters suitable for mimicking phenomena such as ablation, disintegration, and plasma formation processes that take place during the hypervelocity ...

Meteoritics &Planetary Science, EarlyView.Abstract The Campo del Cielo iron meteorite (IAB‐MG) provides a unique window into early solar system processes, particularly the formation and evolution of carbon phases in non‐magmatic iron meteorites. In this study, we conducted a systematic nanostructural investigation of three distinct graphite occurrences—cliftonite (type I), interstitial ...

Thermal Alteration of Labile Elements in Carbonaceous Chondrites
, 2018 Carbonaceous chondrite meteorites are some of the oldest Solar System planetary materials available for study. The CI group has bulk abundances of elements similar to those of the solar photosphere.

Small but mighty: Impact hazards from iron Near‐Earth Objects
Meteoritics &Planetary Science, EarlyView.Abstract Small asteroids can impact Earth unexpectedly, as demonstrated by the Chelyabinsk event in 2013. The warning times are likely to be short, and the first tools for fast hazard predictions have been developed in the last years for encounters with rocky or cometary objects, which quickly fragment in the atmosphere and cause airbursts. However, in

Quantitative FT-IR Analysis for Chondritic Meteorites: Search for C_60 in Meteorites [PDF]
Journal of Astronomy and Space Sciences, 1998 Infrared absorption spectra of 9 bulk samples and 3 acid residues of meteorites were obtained in the mid-infrared region (4000 ~ 400 cm^(-1)). From the known composition of meteorites studied, the possible absorption modes were investigated.

A Portable Magnetometer for Magnetic Measurements of Meter‐Sized Meteorites
Geochemistry, Geophysics, Geosystems, 2020 Meteorites contain records of past magnetic fields in the form of natural remanent magnetization (NRM). A key property of meteorite magnetization that provides information about its origin is its dependence on spatial scale.

The formation of the solar system
, 2015 The solar system started to form about 4.56 Gyr ago and despite the long intervening time span, there still exist several clues about its formation. The three major sources for this information are meteorites, the present solar system structure and the ...
