The Geological Record of Meteorite Impacts
Meteorite impact structures are found on all planetary bodies in the Solar System with a solid surface. On the Moon, Mercury, and much of Mars, impact craters are the dominant landform. On Earth, 174 impact sites have been recognized, with several more new craters being discovered each year. The terrestrial impact cratering record is critical for our understanding of impacts as it currently provides the only ground-truth data on which to base interpretations of the cratering record of other planets and moons. In this contribution, I summarize the processes and products of impact cratering and provide and an up-to-date assessment of the geological record of meteorite impacts.
Great Balls of Fire? Pyrites, Meteorites and Meteor-wrongs from Ancient Iran - 2008
Iranica Antiqua
Metallic nodules found in the Siyalk II settlement and in Iron Age III tombs in Luristan, Iran, were identified by the excavators as meteorites. However, these identifications must be questioned. The Siyalk nodules could be of telluric origin. The four Luristan specimens are identified as pyrite nodules. It is suggested that such nodules were used for fire-making, although other functions such as a use as sling balls are not to be excluded either.
Evidence for a ∼200–100 ka meteorite impact in the Western Desert of Egypt
Earth and Planetary Science Letters, 2007
In this study, we present evidence, in the form of unusual silicate glasses, for a meteorite impact event ∼ 200-100 ka in the Dakhleh Oasis, Western Desert, Egypt. These glasses, known locally as Dakhleh Glass, were derived from the shock melting of a series of unconsolidated sediments underlain by interbedded carbonates, sandstones and phosphate-rich lithologies. Hypervelocity impact in to a volatile-rich target resulted in the production of impact glasses with CaO and Al 2 O 3 contents of up to ∼ 25 and 18 wt.%, respectively. Other notable properties include the presence of globules of immiscible calcite and pyrrhotite melt phases, shattered quartz grains, and fragments of silicified plant matter. Dating of geoarchaeological artefacts associated with the Dakhleh Glass support preliminary 40 Ar/ 39 Ar data, indicating a ∼ 200-100 ka age for the impact event. Geoarchaeological evidence indicates that archaic Homo sapiens and early modern humans continually inhabited this region of the Western Desert during this period. While it is unclear at present whether the Dakhleh Glass was formed during a cratering event or a large aerial burst, the effect on the environment and inhabitants of Dakhleh would have been catastrophic.

“Chiemgau Impact” is an event which took place in the Bronze Age / Iron Age with the creation of a large meteorite strewn field by the impact of a comet / asteroid in southeast Bavaria. The research is interdisciplinary from the outset. It covers, among other things, geology, geophysics, limnology, archaeology, mineralogy, speleology, astronomy, and historical sciences. The research results show that a major disaster must have taken place in the area between Altötting, the Lake Chiemsee, and the Alps. Finds of exotic material, found only in meteorites, extremely stressed and altered rocks, caused by extreme pressures, high temperatures and the action of acid, strange carbon spherules, glass-like carbon, nanodiamonds, magnetic anomalies, soil compaction, sinkholes, and many other abnormalities can be explained by the hypothesis of a post-ice age impact. All the impact criteria required according to scientific standards were demonstrated. The impact associated with a large air blast may have produced considerable regional and probably transregional effects. People not only from the Chiemgau region were witnesses of the fascinating, shocking and disturbing event. Perhaps quite accurate descriptions of the event and the regional effects were even described in the ancient Greek myth of the young racer Phaeton, driving the solar chariot. The paper presents the current (2017) state of knowledge and briefly also the research history.

We present evidence that in ~ 1650 BCE (~ 3600 years ago), a cosmic airburst destroyed Tall el-Hammam, a Middle-Bronze-Age city in the southern Jordan Valley northeast of the Dead Sea. The proposed airburst was larger than the 1908 explosion over Tunguska, Russia, where a ~ 50-m-wide bolide detonated with ~ 1000× more energy than the Hiroshima atomic bomb. A city-wide ~ 1.5-m-thick carbon-and-ash-rich destruction layer contains peak concentrations of shocked quartz (~ 5–10 GPa); melted pottery and mudbricks; diamond-like carbon; soot; Fe- and Si-rich spherules; CaCO3 spherules from melted plaster; and melted platinum, iridium, nickel, gold, silver, zircon, chromite, and quartz. Heating experiments indicate temperatures exceeded 2000 °C. Amid city-side devastation, the airburst demolished 12+ m of the 4-to-5-story palace complex and the massive 4-m-thick mudbrick rampart, while causing extreme disarticulation and skeletal fragmentation in nearby humans. An airburst-related influx of ...
