... correct, since the formation of jadeite in Novosibirsk and Chelyabinsk meteorites was based on crystallization from melt, whereas previously found jadeites were seen as products of solid-state reaction and formed from plagioclase during pressure-temperature increasing stage ( Miyahara et al., 2013...

...Aaron J. Cavosie; Christian Koeberl Abstract Atmospheric airbursts over Russia at Chelyabinsk in 2013 and Tunguska in 1908 provide dramatic examples of hazards posed by near-Earth objects (NEOs). These two events produced 0.5 and 5 Mt of energy, respectively, which dramatically affected surface...

... vaporize, producing a meteor ( Ceplecha and Revelle, 2005 ). In most instances, the ground shaking is triggered by the atmospheric shock wave of a meteor, not by the impact of the surviving meteorites ( Edwards et al. , 2008 ). A particularly strong shock wave can be generated by explosive...

... fragments of the meteorite several centimeters in diameter have been recovered from the region surrounding Chelyabinsk. The meteorite will probably be named the Chebarkul meteorite due to large fragments having been recovered from near Lake Chebarkul, west of Chelyabinsk and near the apparent termination...

...F igure 6 On 15 February 2013, an Apollo-group near-Earth asteroid entered the Earth's atmosphere and became the Chelyabinsk meteor ( upper panel ), which was captured on cameras over the southern Ural region (Russia). The impact sites of some of the fragments of the Chelyabinsk meteorite have...

... fragments. Both localities (at mines 1-2 and 3) were marked in the history of the Chelyabinsk meteorite fall in 2013 since they were in the zone of meteorite shower. As a result, a large number of “meteorite artifacts” were found in the vicinity of the settlement Baturinsky because some of intensely fused...

... of the Chelyabinsk brown-coal basin. Exsolved fayalite and kirschsteinite rims surround the grains of fayalite and early Mg-Fe olivine. The chemical study of the olivines has shown that during their crystallisation they were becoming enriched in fayalite and larnite and depleted in forsterite. The intergrowths...

The appearance of Fe 2+ -bearing phosphates (galileiite, sarcopside, graftonite etc .) as small globules is characteristic of impact melting of meteorites enriched in metal, for example, the Chelyabinsk LL5 chondrite ( Sharygin et al ., 2015 ). Better understanding of the chemistry and mineralogy...

In the Early Cretaceous, ∼80% of the extraterrestrial spinels originated from ordinary chondrites. The ratios between...

... is associated with the fall of remnant materials in the form of meteorites, but these typically fall at terminal velocities measured in km/h rather than km/s. Fortunately, a person presents a relatively low‐impact cross section, whereas buildings and infrastructure provide larger targets (e.g., Brown et al...

Nickel-rich iron with elevated Co (1–1.8 wt.%), Ge (50–140 ppm), and Ga (20–190 ppm) contents suggests a cosmogenic source. Twelve...
