Christopher Chyba and others have proposed a process whereby a stony meteorite could have exhibited the behaviour of the Tunguska impactor.

A farmer might recognize an iron meteorite in his field, says Harvey, but overlook a stony meteorite that looks similar to nearby rocks.

On the morning of 14 July 2006, a bolide exploded above the nearby town of Rygge-moments later, several stony meteorites fell over Moss.

In the 1960s, he discovered that an excess of xenon gas trapped in stony meteorites was a vestige of an extinct iodine isotope.

The traditional way of subdividing meteorites ( see Meteorites classification ) is into irons, stony-irons, and two major groups of stony meteorites, chondrites and achondrites.

When a 250-foot-wide stony meteorite-- about 400 times smaller than Fragment F-- exploded over Siberia in 1908, the shock wave flattened an area 20 miles across.

The impactor is believed to have been a chondrite or stony meteorite some 30 to 50 m in diameter that was vaporized during the impact event.

Stony meteorites which make up the large majority of meteorites that fall may not have a high enough nickel iron content to set off a metal detector.

Stony meteorites however, exhibited very high 207 Pb / 204 Pb versus 206 Pb / 204 Pb ratios, indicating that these samples came from the crust or mantle of the planetesimal.

A few other events of interest took place during this time, including the June 16, 1911 impact of a 772-gram stony meteorite in rural Columbia County near the city, damaging a barn.
