Newfound crater in Egypt could change estimates of impact risk to Earth

A small impact crater discovered in the Egyptian desert could change estimates for impact hazards to our planet, according to a new study.
The 45-metre-wide, 16-metre-deep hole is believed to have smashed into the desert - nearly intact - at speeds exceeding 3.5 kilometres a second.

Egitto, cratere meteoritico scoperto con Google Earth da una spedizione italiana

Era l'età della pietra, circa 5 mila anni fa, e nell'Egitto meridionale già avanzava il processo di desertificazione, quando un blocco metallico di una decina di tonnellate, poco più di un metro di diametro, piombò dallo spazio sulla Terra e colpì una località che oggi si chiama Kamil, al confine con Libia e Sudan, non lontana da un villaggio neolitico. Gli uomini assistettero atterriti a un'esplosione, al tremore della terra e alla frantumazione del corpo impattante in milioni di pezzi. Sul terreno fumante rimase una buca grande una cinquantina di metri e profonda poco meno di venti: uno dei crateri da impatto che costellano la superficie del nostro pianeta.

"Fresh" Crater Found in Egypt

A small impact crater discovered in the Egyptian desert could change estimates for impact hazards to our planet, according to a new study.
One of the best preserved craters yet found on Earth, the Kamil crater was initially discovered in February during a survey of satellite images on Google Earth. Researchers think the crater formed within the past couple thousand years.

Title: The Kamil Crater in Egypt
Authors: Luigi Folco, Mario Di Martino, Ahmed El Barkooky, Massimo D'Orazio, Ahmed Lethy, Stefano Urbini, Iacopo Nicolosi, Mahfooz Hafez, Carole Cordier, Matthias van Ginneken, Antonio Zeoli, Ali M. Radwan, Sami El Khrepy, Mohamed El Gabry, Mahomoud Gomaa, Aly A. Barakat, Romano Serra, Mohamed El Sharkawi

We report on the detection in southern Egypt of an impact crater 45 meters in diameter with a pristine rayed structure. Such pristine structures are typically observed on atmosphereless rocky or icy planetary bodies in the solar system. This feature and the association with an iron meteorite impactor and shock metamorphism provide a unique picture of small-scale hypervelocity impacts on the Earth's crust. Contrary to current geophysical models, ground data indicate that iron meteorites with masses of the order of tens of tons can penetrate the atmosphere without significant fragmentation.

The author has discovered further crater-fields using Google-Earth, which are located in east of Djebel Uweinat (Djebel Kamil) and southwest of this in northern Sudan. Most of the structures are similarly of them in the large crater - field "GKCF" in the east of Gilf Kebir ("Contour").
Amid the crater-shaped structures are to be recognised basaltic cones. The structures in the Djebel Kamil have great similarity to the Clayton Craters at the Gilf Kebir. The crater-field in the Djebel Kamil has the coordinates between 21° 58' to 22° 03' N and 26° 13' to 26° 20' E. The crater-field in the northern Sudan has the coordinates 21°50' to 21°58' N and 25°51' to 26° 00' E.

The crater field has more than 1300 small crater-like structures distributed over an area of 40,000 km2 in the Western Egyptian Desert, near to the Gilf Kebir plateau

Title: Discovery of the largest impact crater field on Earth in the Gilf Kebir region, Egypt
Authors: Philippe Paillou, Ahmed El Barkooky, Aly Barakat, Jean-Marie Malezieux, Bruno Reynard, Jean Dejax, Essam Heggy

Using orbital imaging radar, we have detected a large number of circular structures in the southwestern Egyptian desert, covering more than 4500 km2 close to the Gilf Kebir plateau in sandstones of Upper Cretaceous. Fieldwork confirmed that it is a new impact crater field: 13 craters from 20 m to 1 km in diameter were studied. The impact origin is confirmed by the observation of shock-related structures, such as shatter cones and planar fractures in quartz grains of breccia. Considering the extension of the crater field, it was possibly created by several meteorites that broke up when entering the atmosphere.

New research on a few of the more than 1,300 enigmatic craters found deep in Egypt's western desert has scientists scratching their heads.
The craters look like they were created by a spectacular ancient rain of meteors, or perhaps from a vast eruption of steam and gas from inside the Earth. Or maybe from something else entirely.

"It is a strange and new thing" - Philippe Paillou of the Observatoire Aquitain des Sciences de l'Univers in Floirac, France. Paillou is the lead author of a report on an expedition to the remote landscape of Egypt's Gilf Kebir region in the October issue of the Journal of African Earth Sciences.
