stony-iron meteorite
A meteorite composed of roughly equal
amounts by weight of silicate minerals
and nickel-iron.
Modern meteoritics considers the stony-irons to consist of just two groups,
the mesosiderites and the pallasites;
however, there is a gradual shading into metal-rich stony
meteorites such as the lodranites
(once considered to be stony-irons) and silicate-rich iron meteorites. Stony-iron
meteorites are less abundant than their stony and iron
cousins, comprising a total known mass of some 10 tons – about 1.8%
of the entire mass of all known meteorites.
